  • Sound issues after trying everything

    - by Lerp
    I cannot get my sound working properly, no matter what I do, there's always some problem. It's very annoying as it's the only thing preventing me from making Ubuntu my main OS. At the moment my sound always plays through both my speakers and my headphones regardless except the sound through the headphones is crackly. It is also a bit quiet even though everything is maxed. I've managed to improve the situation to a point where the sound out of my speakers is perfect but I have none at all from my headphones. I do have two connectors listed in the sound settings but regardless of which one is selected it always plays through the speakers. I think this might have something to do with the fact that my speakers are plugging into the front of my computer, typically the headphone jack, and my headphones are plugging into the back but when I try disconnecting the speakers from the front there is still no sound from the headphones. I fixed the speaker sound by going through the sound settings and making sure they were all set to 100% then rebooting. Things I have tried: Maxing everything and unmuting everything in alsamixer Uninstalling pulseaudio Making gstreamer use only alsa via gstreamer-properties. This worked with the sound test button including independent sound between headphones and speakers but when I reset the computer it no longer worked. So I tried setting it manually in gconf-editor which didn't work either. Reinstalling alsa and pulseaudio Setting the model in /etc/modprobe.d/alsa-base.conf to 6stack and 6stack-dig neither worked. Upgrading to 12.10 Here's some command output to help you diagnose my problem. aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: AD198x Digital [AD198x Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 2: AD198x Headphone [AD198x Headphone] Subdevices: 1/1 Subdevice #0: subdevice #0 sudo lshw -C sound *-multimedia description: Audio device product: 82801JI (ICH10 Family) HD Audio Controller vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 00 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=snd_hda_intel latency=0 resources: irq:70 memory:f7ff8000-f7ffbfff cat /proc/asound/card*/codec* | grep "Codec" Codec: Analog Devices AD1989B cat /etc/modprobe.d/alsa-base.conf # autoloader aliases install sound-slot-0 /sbin/modprobe snd-card-0 install sound-slot-1 /sbin/modprobe snd-card-1 install sound-slot-2 /sbin/modprobe snd-card-2 install sound-slot-3 /sbin/modprobe snd-card-3 install sound-slot-4 /sbin/modprobe snd-card-4 install sound-slot-5 /sbin/modprobe snd-card-5 install sound-slot-6 /sbin/modprobe snd-card-6 install sound-slot-7 /sbin/modprobe snd-card-7 # Cause optional modules to be loaded above generic modules install snd /sbin/modprobe --ignore-install snd $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-ioctl32 ; /sbin/modprobe --quiet --use-blacklist snd-seq ; } # # Workaround at bug #499695 (reverted in Ubuntu see LP #319505) install snd-pcm /sbin/modprobe --ignore-install snd-pcm $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-pcm-oss ; : ; } install snd-mixer /sbin/modprobe --ignore-install snd-mixer $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-mixer-oss ; : ; } install snd-seq /sbin/modprobe --ignore-install snd-seq $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-seq-midi ; /sbin/modprobe --quiet --use-blacklist snd-seq-oss ; : ; } # install snd-rawmidi /sbin/modprobe --ignore-install snd-rawmidi $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-seq-midi ; : ; } # Cause optional modules to be loaded above sound card driver modules install snd-emu10k1 /sbin/modprobe --ignore-install snd-emu10k1 $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-emu10k1-synth ; } install snd-via82xx /sbin/modprobe --ignore-install snd-via82xx $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-seq ; } # Load saa7134-alsa instead of saa7134 (which gets dragged in by it anyway) install saa7134 /sbin/modprobe --ignore-install saa7134 $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist saa7134-alsa ; : ; } # Prevent abnormal drivers from grabbing index 0 options bt87x index=-2 options cx88_alsa index=-2 options saa7134-alsa index=-2 options snd-atiixp-modem index=-2 options snd-intel8x0m index=-2 options snd-via82xx-modem index=-2 options snd-usb-audio index=-2 options snd-usb-caiaq index=-2 options snd-usb-ua101 index=-2 options snd-usb-us122l index=-2 options snd-usb-usx2y index=-2 # Ubuntu #62691, enable MPU for snd-cmipci options snd-cmipci mpu_port=0x330 fm_port=0x388 # Keep snd-pcsp from being loaded as first soundcard options snd-pcsp index=-2 # Keep snd-usb-audio from beeing loaded as first soundcard options snd-usb-audio index=-2 options snd-hda-intel model=6stack

  • recommendations for rich scalable internet application

    - by Wouter Roux
    I am planning to develop a web application that must perform the following actions: User authentication allow authenticated user to download data from USB device (roughly 5 meg data) upload the data from the USB device to processing server process the data and display the results to the user further requirements/restrictions: the USB driver supports windows (2000, XP, Vista, 7) the application must support IE, Firefox and Chrome the USB driver must be installed when pointing to the web application the first time the USB driver exposes functionality through exported functions in dll scalability and eye candy is important server details: Windows Server 2008 Enterprise x64, IIS 7.0, SQL server 2008 With the limited details specified: What technology would you recommend? (eg silverlight/asp.net mvc/wcf). What practices/patterns/3rd party controls would you recommend?

  • Unexpected advantage of Engineered Systems

    - by user12244672
    It's not surprising that Engineered Systems accelerate the debugging and resolution of customer issues. But what has surprised me is just how much faster issue resolution is with Engineered Systems such as SPARC SuperCluster. These are powerful, complex, systems used by customers wanting extreme database performance, app performance, and cost saving server consolidation. A SPARC SuperCluster consists or 2 or 4 powerful T4-4 compute nodes, 3 or 6 extreme performance Exadata Storage Cells, a ZFS Storage Appliance 7320 for general purpose storage, and ultra fast Infiniband switches.  Each with its own firmware. It runs Solaris 11, Solaris 10, 11gR2, LDoms virtualization, and Zones virtualization on the T4-4 compute nodes, a modified version of Solaris 11 in the ZFS Storage Appliance, a modified and highly tuned version of Oracle Linux running Exadata software on the Storage Cells, another Linux derivative in the Infiniband switches, etc. It has an Infiniband data network between the components, a 10Gb data network to the outside world, and a 1Gb management network. And customers can run whatever middleware and apps they want on it, clustered in whatever way they want. In one word, powerful.  In another, complex. The system is highly Engineered.  But it's designed to run general purpose applications. That is, the physical components, configuration, cabling, virtualization technologies, switches, firmware, Operating System versions, network protocols, tunables, etc. are all preset for optimum performance and robustness. That improves the customer experience as what the customer runs leverages our technical know-how and best practices and is what we've tested intensely within Oracle. It should also make debugging easier by fixing a large number of variables which would otherwise be in play if a customer or Systems Integrator had assembled such a complex system themselves from the constituent components.  For example, there's myriad network protocols which could be used with Infiniband.  Myriad ways the components could be interconnected, myriad tunable settings, etc. But what has really surprised me - and I've been working in this area for 15 years now - is just how much easier and faster Engineered Systems have made debugging and issue resolution. All those error opportunities for sub-optimal cabling, unusual network protocols, sub-optimal deployment of virtualization technologies, issues with 3rd party storage, issues with 3rd party multi-pathing products, etc., are simply taken out of the equation. All those error opportunities for making an issue unique to a particular set-up, the "why aren't we seeing this on any other system ?" type questions, the doubts, just go away when we or a customer discover an issue on an Engineered System. It enables a really honed response, getting to the root cause much, much faster than would otherwise be the case. Here's a couple of examples from the last month, one found in-house by my team, one found by a customer: Example 1: We found a node eviction issue running 11gR2 with Solaris 11 SRU 12 under extreme load on what we call our ExaLego test system (mimics an Exadata / SuperCluster 11gR2 Exadata Storage Cell set-up).  We quickly established that an enhancement in SRU12 enabled an 11gR2 process to query Infiniband's Subnet Manager, replacing a fallback mechanism it had used previously.  Under abnormally heavy load, the query could return results which were misinterpreted resulting in node eviction.  In several daily joint debugging sessions between the Solaris, Infiniband, and 11gR2 teams, the issue was fully root caused, evaluated, and a fix agreed upon.  That fix went back into all Solaris releases the following Monday.  From initial issue discovery to the fix being put back into all Solaris releases was just 10 days. Example 2: A customer reported sporadic performance degradation.  The reasons were unclear and the information sparse.  The SPARC SuperCluster Engineered Systems support teams which comprises both SPARC/Solaris and Database/Exadata experts worked to root cause the issue.  A number of contributing factors were discovered, including tunable parameters.  An intense collaborative investigation between the engineering teams identified the root cause to a CPU bound networking thread which was being starved of CPU cycles under extreme load.  Workarounds were identified.  Modifications have been put back into 11gR2 to alleviate the issue and a development project already underway within Solaris has been sped up to provide the final resolution on the Solaris side.  The fixed SPARC SuperCluster configuration greatly aided issue reproduction and dramatically sped up root cause analysis, allowing the correct workarounds and fixes to be identified, prioritized, and implemented.  The customer is now extremely happy with performance and robustness.  Since the configuration is common to other customers, the lessons learned are being proactively rolled out to other customers and incorporated into the installation procedures for future customers.  This effectively acts as a turbo-boost to performance and reliability for all SPARC SuperCluster customers.  If this had occurred in a "home grown" system of this complexity, I expect it would have taken at least 6 months to get to the bottom of the issue.  But because it was an Engineered System, known, understood, and qualified by both the Solaris and Database teams, we were able to collaborate closely to identify cause and effect and expedite a solution for the customer.  That is a key advantage of Engineered Systems which should not be underestimated.  Indeed, the initial issue mitigation on the Database side followed by final fix on the Solaris side, highlights the high degree of collaboration and excellent teamwork between the Oracle engineering teams.  It's a compelling advantage of the integrated Oracle Red Stack in general and Engineered Systems in particular.

  • use hg to synchronize my project between my two computer

    - by hguser
    Hi: I have two computer : the desktop in my company and the portable computer in my home. Now I want to use the hg to synchronize the project between them using a "USB removable disk". So I wonder how to implement it? THe pro in my desktop is : D:\work\mypro. I use the following command to init it: hg init Then I connect to the USB disk whose volume label is "H",and get a clone using: cd H: hg init hg clone D:\work\mypro mypro-usb ANd in my portable computer I use: cd D: hg clone H:\mypro-usb mypro-home However I do not know how to do if I modify some files(remove or add and modify) in the mypro-home,how to make the mypro-usb changed synchronizely,also I want the mypro in my desktop synchronizely. How to do it?

  • Multiple Audio Issues

    - by Lerp
    I am having issues with my audio on Ubuntu 12.04, I will try and give as much detail as possible so sorry if there's too much detail. The Problem Audio plays from both speakers and headphone regardless of what connector I choose and regardless of the profile I use. The microphone is constantly being played through headphones & speakers. The headphone audio is extremely quiet but plays from both ears when I select "Headphones" for the connector in Sound Settings. The headphone audio only plays from one ear and is quiet (but not as quiet as above) when I select "Analogue Output" for the connector in Sound Settings. I can only select "Headphones" as the connector in Sound Settings if I set the profile to either "Analogue Stereo Output/Duplex", all others only allow me to choose "Analogue Output" for the connector. Despite the headphone sound issues, the speaker sound is fine apart from the fact that I am not able to select which output is used, they just both play. My headphone and microphone are plugged into the front and my speakers are plugged into the back. What I have tried I have put everything in alsamixer to 100 apart from "Front Mic Boost" which I have set to 0.

  • Intel I217LM ethernet controller not detected by Ubuntu 12.04LTS

    - by Alexandr Kurilin
    My last installation of Ubuntu 12.04 on a machine using an ASUS Q87M-E motherboard with an Intel I217LM Ethernet controller has failed to detect the ethernet card. The only thing displayed by ifconfig -a is the loopback.

Time to become a meteorologist. To be honest I don’t know how to start. Is cloud better or worse than on campus resources … hmm … it is just different. I think for successful adoption in cloud world IT Dinosaurs need to forget some “Private Cloud” virtualization bad habits, and learn new way of thinking. Take a look: - I don’t need any  tapes or  CDs  (Physical Kingdom of Windows XP and 2000) - I don’t need any locally stored MP3s (CD virtualization :-) - I can just stream music to your computer no matter whether my on-site infrastructure is powered on. Why not to do exactly the same with WebServer, SQL, or just rented for a while Windows server ? Let’s go, to the other side of the mirror. 1st  - register yourself for free one month trial, as happy MSDN subscriber you’ve got monthly budget to spent. In addition in default setting your limit protects you against loosing real money, if your toys will consume too much traffic and space. http://azure.microsoft.com/en-us/pricing/free-trial/ Once your account is ready forget WebPortal, we are PowerShell knights. http://go.microsoft.com/?linkid=9811175&clcid=0x409 #Authenticate yourself in Azure Add-AzureAccount #download once your settings file Get-AzurePublishSettingsFile #Import it to your PowerShell Module Import-AzurePublishSettingsFile "C:\Azure\[filename].publishsettings" #validation Get-AzureAccount Get-AzureSubscription #where are Azure datacenters Get-AzureLocation #You will need it Update-Help #storage account is related to physical location, there are two datacenters on each continent, try nearest to you # all your VMs will store VHD files on your storage account #your storage account must be unique globally, so I assume that words account or server are already used New-AzureStorageAccount -StorageAccountName "[YOUR_STORAGE_ACCOUNT]" -Label "AzureTwo" -Location "West Europe" Get-AzureStorageAccount #it looks like you are ready to deploy first VM, what templates we can use Get-AzureVMImage | Select ImageName #what a mess, let’s choose Server 2012 $ImageName = (Get-AzureVMImage)[74].ImageName $cloudSvcName = '[YOUR_STORAGE_ACCOUNT]' $AdminUsername = "[YOUR-ADMIN]" $adminPassword = '[YOUR_PA$$W0RD]' $MediaLocation = "West Europe" $vmnameDC = 'DC01' #burn baby burn !!! $vmDC01 = New-AzureVMConfig -Name $vmnameDC -InstanceSize "Small" -ImageName $ImageName   `     | Add-AzureProvisioningConfig -Windows -Password $adminPassword -AdminUsername $AdminUsername   `     | New-AzureVM -ServiceName $cloudSvcName #ice, ice baby … Get-AzureVM Get-AzureRemoteDesktopFile -ServiceName "[YOUR_STORAGE_ACCOUNT]" -Name "DC01" -LocalPath "c:\AZURE\DC01.rdp" As you can see it is not just a new-VM, you need to associate your VM with AzureVMConfig (it sets your template), AzureProvisioningConfig (it sets your customizations), and Storage account. In next releases you’ll need to put this machine in specific subnet, attach a HDD and many more. After second reading I found that I am using the same name for STORAGE and SERVICE account, please be aware of it if you need to split these values. Conclusions: - pipe rules ! - at the beginning it is hard to change your mind and agree with fact that it is easier to remove and recreate a VM than move it to different subnet - by default everything is firewalled, limited access to DNS, but NATed outside on custom ports. It is good to check these translations sometimes on the webportal. - if you remove your VMs your harddrives remains on storage and MS will charge you . Remove-AzureVM -DeleteVHD For me AZURE it is a lot of fun, once again I can be newbie and learn every page. For me Azure offers real freedom in deployment of VMs without arguing with NetAdmins, WinAdmins, DBAs, PMs and other Change Managers.

  • Blueprints for Oracle NoSQL Database

    - by dan.mcclary
    I think that some of the most interesting analytic problems are graph problems.  I'm always interested in new ways to store and access graphs.  As such, I really like the work being done by Tinkerpop to create Open Source Software to make property graphs more accessible over a wide variety of datastores.  Since key-value stores like Oracle NoSQL Database are well-suited to storing property graphs, I decided to extend the Blueprints API to work with it.  Below I'll discuss some of the implementation details, but you can check out the finished product here: http://github.com/dwmclary/blueprints-oracle-nosqldb.  What's in a Property Graph?  In the most general sense, a graph is just a collection of vertices and edges.  Vertices and edges can have properties: weights, names, or any number of other traits.  In an undirected graph, edges connect vertices without direction.  A directed graph specifies that all edges have a head and a tail --- a direction.  A multi-graph allows multiple edges to connect two vertices.  A "property graph" encompasses all of these traits. Key-Value Stores for Property Graphs Key-Value stores like Oracle NoSQL Database tend to be ideal for implementing property graphs.  First, if any vertex or edge can have any number of traits, we can treat it as a hash map.  For example: Vertex["name"] = "Mary" Vertex["age"] = 28 Vertex["ID"] = 12345  and so on.  This is a natural key-value relationship: the key "name" maps to the value "Mary."  Moreover if we maintain two hash maps, one for vertex objects and one for edge objects, we've essentially captured the graph.  As such, any scalable key-value store is fertile ground for planting graphs. Oracle NoSQL Database as a Scalable Graph Database While Oracle NoSQL Database offers useful features like tunable consistency, what lends it to storing property graphs is the storage guarantees around its key structure.  Keys in Oracle NoSQL Database are divided into two parts: a major key and a minor key.  The storage guarantee is simple.  Major keys will be distributed across storage nodes, which could encompass a large number of servers.  However, all minor keys which are children of a given major key are guaranteed to be stored on the same storage node.  For example, the vertices: /Personnel/Vertex/1  and /Personnel/Vertex/2 May be stored on different servers, but /Personnel/Vertex/1-/name and  /Personnel/Vertex/1-/age will always be on the same server.  This means that we can structure our graph database such that retrieving all the properties for a vertex or edge requires I/O from only a single storage node.  Moreover, Oracle NoSQL Database provides a storeIterator which allows us to store a huge number of vertices and edges in a scalable fashion.  By storing the vertices and edges as major keys, we guarantee that they are distributed evenly across all storage nodes.  At the same time we can use a partial major key to iterate over all the vertices or edges (e.g. we search over /Personnel/Vertex to iterate over all vertices). Fork It! The Blueprints API and Oracle NoSQL Database present a great way to get started using a scalable key-value database to store and access graph data.  However, a graph store isn't useful without a good graph to work on.  I encourage you to fork or pull the repository, store some data, and try using Gremlin or any other language to explore.

  • The Power to Control Power

    - by speakjava
    I'm currently working on a number of projects using embedded Java on the Raspberry Pi and Beagle Board.  These are nice and small, so don't take up much room on my desk as you can see in this picture. As you can also see I have power and network connections emerging from under my desk.  One of the (admittedly very minor) drawbacks of these systems is that they have no on/off switch.  Instead you insert or remove the power connector (USB for the RasPi, a barrel connector for the Beagle).  For the Beagle Board this can potentially be an issue; with the micro-SD card located right next to the connector it has been known for people to eject the card when trying to power off the board, which can be quite serious for the hardware. The alternative is obviously to leave the boards plugged in and then disconnect the power from the outlet.  Simple enough, but a picture of underneath my desk shows that this is not the ideal situation either. This made me think that it would be great if I could have some way of controlling a mains voltage outlet using a remote switch or, even better, from software via a USB connector.  A search revealed not much that fit my requirements, and anything that was close seemed very expensive.  Obviously the only way to solve this was to build my own.Here's my solution.  I decided my system would support both control mechanisms (remote physical switch and USB computer control) and be modular in its design for optimum flexibility.  I did a bit of searching and found a company in Hong Kong that were offering solid state relays for 99p plus shipping (£2.99, but still made the total price very reasonable).  These would handle up to 380V AC on the output side so more than capable of coping with the UK 240V supply.  The other great thing was that being solid state, the input would work with a range of 3-32V and required a very low current of 7.5mA at 12V.  For the USB control an Arduino board seemed the obvious low-cost and simple choice.  Given the current requirments of the relay, the Arduino would not require the additional power supply and could be powered just from the USB.Having secured the relays I popped down to Homebase for a couple of 13A sockets, RS for a box and an Arduino and Maplin for a toggle switch.  The circuit is pretty straightforward, as shown in the diagram (only one output is shown to make it as simple as possible).  Originally I used a 2 pole toggle switch to select the remote switch or USB control by switching the negative connections of the low voltage side.  Unfortunately, the resistance between the digital pins of the Arduino board was not high enough, so when using one of the remote switches it would turn on both of the outlets.  I changed to a 4 pole switch and isolated both positive and negative connections. IMPORTANT NOTE: If you want to follow my design, please be aware that it requires working with mains voltages.  If you are at all concerned with your ability to do this please consult a qualified electrician to help you.It was a tight fit, especially getting the Arduino in, but in the end it all worked.  The completed box is shown in the photos. The remote switch was pretty simple just requiring the squeezing of two rocker switches and a 9V battery into the small RS supplied box.  I repurposed a standard stereo cable with phono plugs to connect the switch box to the mains outlets.  I chopped off one set of plugs and wired it to the rocker switches.  The photo shows the RasPi and the Beagle board now controllable from the switch box on the desk. I've tested the Arduino side of things and this works fine.  Next I need to write some software to provide an interface for control of the outlets.  I'm thinking a JavaFX GUI would be in keeping with the total overkill style of this project.

  • Dell 3721 Wifi problem Ubuntu 13.04

    - by Sebastian
    I have a Dell 3721 which comes original with windows 8. I managed it to install ubuntu 12.10 on this laptop, even there was no out of the box drivers. With 12.10 I was forces to install this .deb package couple of times. After installing it, it was ok for some weeks before I have to install it again. Maybe some security updates destroy something which made in necessary to install it again... http://jas.gemnetworks.com/debian/pool/main/w/wireless-bcm43142/wireless-bcm43142-dkms_6.20.55.19-1_amd64.deb My problem is, that this package isnt working with ubuntu 13.04 anymore. So I cant use Wifi now. Also my display is almost dark, I cant change the brightness level with ubuntu 13.04. Hope you can give me some advice.

  • 12.04 making BCM4313 card work with aircrack-ng?

    - by Charles Forest
    I'm a real Linux Noob, just started using it (this month) and until now i had no issues. now i'm trying to set-up aircrack-ng on my laptop, but it seems like it's using the worst card possible (or almost) there is a TON of tutorial on this card (seems to be hell to set-up) i have tryed some, but i ended up uninstalling my drivers, messing with my desktops, and ended by having no more "X" to close my windows (i have no clue how i ended there) i just re-installed my linux (took me 2 hours to setup everything again), but now i'm a bit "Scared" to try tutorials randomly again. Right now it says the driver is wl, wich is not the one i want (AFAIK it's not supported) i'm not sure what kind of informations are needed, but here's what i think could be usefull. lspci -knn 00:00.0 Host bridge [0600]: Intel Corporation 2nd Generation Core Processor Family DRAM Controller [8086:0104] (rev 09) Subsystem: Samsung Electronics Co Ltd Device [144d:c0a5] Kernel driver in use: agpgart-intel 00:01.0 PCI bridge [0604]: Intel Corporation Xeon E3-1200/2nd Generation Core Processor Family PCI Express Root Port [8086:0101] (rev 09) Kernel driver in use: pcieport Kernel modules: shpchp 00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09) Subsystem: Samsung Electronics Co Ltd Device [144d:c0a5] Kernel driver in use: i915 Kernel modules: i915 00:16.0 Communication controller [0780]: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 [8086:1c3a] (rev 04) Subsystem: Samsung Electronics Co Ltd Device [144d:c0a5] Kernel driver in use: mei Kernel modules: mei 00:1a.0 USB controller [0c03]: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 [8086:1c2d] (rev 04) Subsystem: Samsung Electronics Co Ltd Device [144d:c0a5] Kernel driver in use: ehci_hcd 00:1b.0 Audio device [0403]: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller [8086:1c20] (rev 04) Subsystem: Samsung Electronics Co Ltd Device [144d:c0a5] Kernel driver in use: snd_hda_intel Kernel modules: snd-hda-intel 00:1c.0 PCI bridge [0604]: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 [8086:1c10] (rev b4) Kernel driver in use: pcieport Kernel modules: shpchp 00:1c.3 PCI bridge [0604]: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 [8086:1c16] (rev b4) Kernel driver in use: pcieport Kernel modules: shpchp 00:1c.4 PCI bridge [0604]: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 5 [8086:1c18] (rev b4) Kernel driver in use: pcieport Kernel modules: shpchp 00:1d.0 USB controller [0c03]: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 [8086:1c26] (rev 04) Subsystem: Samsung Electronics Co Ltd Device [144d:c0a5] Kernel driver in use: ehci_hcd 00:1f.0 ISA bridge [0601]: Intel Corporation HM65 Express Chipset Family LPC Controller [8086:1c49] (rev 04) Subsystem: Samsung Electronics Co Ltd Device [144d:c0a5] Kernel modules: iTCO_wdt 00:1f.2 SATA controller [0106]: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller [8086:1c03] (rev 04) Subsystem: Samsung Electronics Co Ltd Device [144d:c0a5] Kernel driver in use: ahci 00:1f.3 SMBus [0c05]: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller [8086:1c22] (rev 04) Subsystem: Samsung Electronics Co Ltd Device [144d:c0a5] Kernel modules: i2c-i801 01:00.0 3D controller [0302]: NVIDIA Corporation GF108 [GeForce GT 540M] [10de:0df4] (rev a1) Subsystem: Samsung Electronics Co Ltd Device [144d:c0a5] Kernel driver in use: nouveau Kernel modules: nouveau, nvidiafb WIRELESS CARD 02:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01) Subsystem: Wistron NeWeb Corp.

  • Upgraded to 12.04 now wifi doesn't work

  • Inode to device information

    - by Methos
    I have 3 questions: I want to figure out if a file belongs to a USB device given the file inode. By looking in the latest kernel sources (2.6.33) on LXR, I think one can find that information by following pointers as follows: inode-super_block-block_device-backing_dev_info-device-device_driver(or device_type). However, the kernel that I am working with - 2.6.22.14 - does not have struct device pointer in the backing_dev_info object. So how can I figure out to which device does a file belong to from just the inode? I see that each of the inode, super_block and block_device contain an object of type 'dev_t'. But even after searching a lot, I could not find out how to convert 'dev_t' into struct device *. Is there any way to get that infomation? I tried to print device major and minor numbers using imajor(inode) and iminor(inode). However, for every file - belonging to hdd or usb - it always prints major and minor number as zero. Why would that be happening? I searched online for USB major numbers and I found out that major number for a USB is 180. However, on multiple machines, it showed me the major number associated with the USB dev as 253. $ ls -ltr /dev/usb* crw-rw---- 1 root root 253, 4 2010-04-13 17:20 /dev/usbmon4 crw-rw---- 1 root root 253, 3 2010-04-13 17:20 /dev/usbmon3 crw-rw---- 1 root root 253, 8 2010-04-13 17:20 /dev/usbmon8 crw-rw---- 1 root root 253, 5 2010-04-13 17:20 /dev/usbmon5 crw-rw---- 1 root root 253, 1 2010-04-13 17:20 /dev/usbmon1 crw-rw---- 1 root root 253, 7 2010-04-13 17:20 /dev/usbmon7 Why is that so?

  • [C#] Linq doesn't insert associated entity on insert.

    - by Tomek
    Hello! I have simple mapping: [Table(Name="Person")] public class Person { private int id; private int state_id; private EntityRef<PersonState> state = new EntityRef<PersonState>(); [Column(IsPrimaryKey = true, Storage = "id", Name="id", IsDbGenerated = true, CanBeNull = false)] public int ID { get { return id; } set { id = value; } } [Column(Storage="state_id", Name="state_id")] public int StateID { get{ return state_id;} set{ state_id = value;} } [Association( Storage = "state", ThisKey = "StateID", IsForeignKey=true)] public PersonState State { get { return state.Entity; } set { state.Entity = value; } } } [Table(Name = "PersonState")] public class PersonState { private int id; private State state; [Column(Name="id", Storage="id", IsDbGenerated=true, IsPrimaryKey=true)] public int ID { get { return id; } set { id = value; } } [Column(Name = "date", Storage = "date")] public DateTime Date { get { return date; } set { date = value; } } [Column(Name = "type", Storage = "state")] public State State { get { return state; } set { state = value; } } } I use this code to insert new person with default state: private static Person NewPerson() { Person p = new Person(); p.State = DefaultState(p); return p; } private static PersonState DefaultState() { PersonState state = new PersonState(); state.Date = DateTime.Now; state.State = State.NotNotified; state.Comment = "Default State!"; return state; } Leater in code: db.Persons.InsertOnSubmit(NewPerson()); db.SubmitChanges(); In database(sqlite) I have all new persons, but state_id of all persons is set to 0, and PersonState table is empty. Why Linq did not insert any State object to database?

  • How do I serialize/deserialize a NHibernate entity that has references to other objects?

    - by Daniel T.
    I have two NHibernate-managed entities that have a bi-directional one-to-many relationship: public class Storage { public virtual string Name { get; set; } public virtual IList<Box> Boxes { get; set; } } public class Box { public virtual string Box { get; set; } [DoNotSerialize] public virtual Storage ParentStorage { get; set; } } A Storage can contain many Boxes, and a Box always belongs in a Storage. I want to edit a Box's name, so I send it to the client using JSON. Note that I don't serialize ParentStorage because I'm not changing which storage it's in. The client edits the name and sends the Box back as JSON. The server deserializes it back into a Box entity. Problem is, the ParentStorage property is null. When I try to save the Box to the database, it updates the name, but also removes the relationship to the Storage. How do I properly serialize and deserialize an entity like a Box, while keeping the JSON data size to a minimum?

  • Dell Vostro 3560 bluetooth doesn't work

    - by Shein
    I installed the wireless driver using this instruction How do I install BCM43142 wireless drivers for Dell Vostro 3460/3560 and I have WiFi working. No problems here. But unfortunately the bluetooth doesn't work. The ubuntu bar shows the bluetooth sign and I can turn the bluetooth on/off but I can't discover any devices. And I can't find my laptop when I turn visibility On. So, obviously bluetooth doesn't work. I couldn't find the reports that blutooth can actually work with this adapter in Ubuntu. So, my question is: Is there anyone with BCM43142 adapter that have bluetooth working? Thank You in advance. PS. Ubuntu 12.10 x64 Update: After some fiddling around with different drivers from different sources I managed to get bluetooth working. Not flawlessly but at least I can pair a device. Bluetooth started working after installation of this package bt-bcm43142-onereic_0.0+20111116somerville2_amd64.deb Originally I found this package on the disk with Ubuntu which came with the Laptop. What this package does, it installs a firmware loader and a firmware itself. This firmware needs to get bluetooth working. Still bluetooth sometimes doesn't work even with this package. But manual loading the firmware helps. brcm_patchram_plus_usb --patchram /lib/firmware/BCM43142A0_001.001.011.0028.0036.hcd hci0 Also I found it strange that this package writes all different ids into /sys/bus/usb/drivers/btusb/new_id because only one from the list matches my device ID bcm43142.conf: install btusb /sbin/modprobe --ignore-install btusb && echo '0a5c 21d3' > /sys/bus/usb/drivers/btusb/new_id && echo '0a5c 21d7' > /sys/bus/usb/drivers/btusb/new_id && echo '0a5c 21e1' > /sys/bus/usb/drivers/btusb/new_id && echo '0a5c 21e3' > /sys/bus/usb/drivers/btusb/new_id && hciconfig hci0 up && /usr/bin/brcm_patchram_plus_usb --patchram /lib/firmware/BCM43142A0_001.001.011.0028.0036.hcd hci0 & My lsusb: ... Bus 002 Device 003: ID 0a5c:21d7 Broadcom Corp. In conclusion: bluetooth works not nearly as good as in windows :( once I even got a complete crash of the system because of the btusb module. Luckily WiFi works perfectly :)

  • Windows and SQL Azure Best Practices: Affinity Groups

    - by BuckWoody
    When you create a Windows Azure application, you’ll pick a subscription to put it under. This is a billing container - underneath that, you’ll deploy a Hosted Service. That holds the Web and Worker Roles that you’ll deploy for your applications. along side that, you use the Storage Account to create storage for the application. (In some cases, you might choose to use only storage or Roles - the info here applies anyway) As you are setting up your environment, you’re asked to pick a “region” where your application will run. If you choose a Region, you’ll be asked where to put the Roles. You’re given choices like Asia, North America and so on. This is where the hardware that physically runs your code lives. We have lots of fault domains, power considerations and so on to keep that set of datacenters running, but keep in mind that this is where the application lives. You also get this selection for Storage Accounts. When you make new storage, it’s a best practice to put it where your computing is. This makes the shortest path from the code to the data, and then back out to the user. One of the selections for the location is “Anywhere U.S.”. This selection might be interpreted to mean that we will bias towards keeping the data and the code together, but that may not be the case. There is a specific abstraction we created for just that purpose: Affinity Groups. An Affinity Group is simply a name you can use to tie together resources. You can do this in two places - when you’re creating the Hosted Service (shown above) and on it’s own tree item on the left, called “Affinity Groups”. When you select either of those actions, You’re presented with a dialog box that allows you to specify a name, and then the Region that  names ties the resources to. Now you can select that Affinity Group just as if it were a Region, and your code and data will stay together. That helps with keeping the performance high.

  • NoSQL is not about object databases

    - by Bertrand Le Roy
    NoSQL as a movement is an interesting beast. I kinda like that it’s negatively defined (I happen to belong myself to at least one other such a-community). It’s not in its roots about proposing one specific new silver bullet to kill an old problem. it’s about challenging the consensus. Actually, blindly and systematically replacing relational databases with object databases would just replace one set of issues with another. No, the point is to recognize that relational databases are not a universal answer -although they have been used as one for so long- and recognize instead that there’s a whole spectrum of data storage solutions out there. Why is it so hard to recognize, by the way? You are already using some of those other data storage solutions every day. Let me cite a few: The file system Active Directory XML / JSON documents The Web e-mail Logs Excel files EXIF blobs in your photos Relational databases And yes, object databases It’s just a fact of modern life. Notice by the way that most of the data that you use every day is unstructured and thus mostly unsuitable for relational storage. It really is more a matter of recognizing it: you are already doing NoSQL. So what happens when for any reason you need to simultaneously query two or more of these heterogeneous data stores? Well, you build an index of sorts combining them, and that’s what you query instead. Of course, there’s not much distance to travel from that to realizing that querying is better done when completely separated from storage. So why am I writing about this today? Well, that’s something I’ve been giving lots of thought, on and off, over the last ten years. When I built my first CMS all that time ago, one of the main problems my customers were facing was to manage and make sense of the mountain of unstructured data that was constituting most of their business. The central entity of that system was the file system because we were dealing with lots of Word documents, PDFs, OCR’d articles, photos and static web pages. We could have stored all that in SQL Server. It would have worked. Ew. I’m so glad we didn’t. Today, I’m working on Orchard (another CMS ;). It’s a pretty young project but already one of the questions we get the most is how to integrate existing data. One of the ideas I’ll be trying hard to sell to the rest of the team in the next few months is to completely split the querying from the storage. Not only does this provide great opportunities for performance optimizations, it gives you homogeneous access to heterogeneous and existing data sources. For free.

  • How can I fix broken i915 drivers for Intel GPUs?

    - by Alen Mujezinovic
    I've got troubles getting the i915 drivers to work correctly on my laptop (HP Pavilion DM4 2101ea). Specifically, the laptop screen goes black and stays black after the splash graphic when booting both from USB key and from harddrive. To get anything on to the display after the splash screen I have to boot either with acpi=off nomodeset i915.modeset=0 I'd rather not turn ACPI off because I like my fans spinning and nomodeset is a bit overkill, so for now I'm booting with i915.modeset=0. Unfortunately, this turns off KMS and my current maximum resolution on the laptop screen is fixed to 1024x768 instead of its real capability. When not setting any of the above boot flags and I plug in an external monitor, the external monitor works fine. When booting with the flags, the external monitor works fine too, but can only do 1024x768 and can't do anything else than mirroring the laptop display. I did upgrade the i915 drivers from 2.17 that ship with Precise to 2.19 which are the most recent ones but without luck of getting anything to display. Here's my lspci output: 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) 00:1c.2 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 3 (rev b5) 00:1c.4 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 5 (rev b5) 00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation HM65 Express Chipset Family LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) 01:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) 02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

If you could provide a method to make i915 work, suggest alternative drivers a way to boot with i915.modeset=0 but higher resolutions and KMS on or explain what is happening and how to fix it I'll give you an answer badge. :) Thanks

  • Link instead of Attaching

    - by Daniel Moth
    With email storage not being an issue in many companies (I think I currently have 25GB of storage on my email account, I don’t even think about storage), this encourages bad behaviors such as liberally attaching office documents to emails instead of sharing a link to the document in SharePoint or SkyDrive or some file share etc. Attaching a file admittedly has its usage scenarios too, but it should not be the default. I thought I'd list the reasons why sharing a link can be better than attaching files directly. In no particular order: Better Review. It allows multiple recipients to review the file and their comments are aggregated into a single document. The alternative is everyone having to detach the document, add their comments, then send back to you, and then you have to collate. Wirth the alternative, you also potentially miss out on recipients reading comments from other recipients. Always up to date. The attachment becomes a fork instead of an always up to date document. For example, you send the email on Thursday, I only open it on Tuesday: between those days you could have made updates that now I am missing because you decided to share a link instead of an attachment. Better bookmarking. When I need to find that document you shared, you are forcing me to search through my email (I may not even be running outlook), instead of opening the link which I have bookmarked in my browser or my collection of links in my OneNote or from the recent/pinned links of the office app on my task bar, etc. Can control access. If someone accidentally or naively forwards your link to someone outside your group/org who you’d prefer not to have access to it, the location of the document can be protected with specific access control. Can add more recipients. If someone adds people to the email thread in outlook, your attachment doesn't get re-attached - instead, the person added is left without the attachment unless someone remembers to re-attach it. If it was a link, they are immediately caught up without further actions. Enable Discovery. If you put it on a share, I may be able to discover other cool stuff that lives alongside that document. Save on storage. So this doesn't apply to me given my opening statement, but if in your company you do have such limitations, attaching files eats up storage on all recipients accounts and will also get "lost" when those people archive email (and lose completely at some point if they follow the company retention policy). Like I said, attachments do have their place, but they should be an explicit choice for explicit reasons rather than the default. Comments about this post by Daniel Moth welcome at the original blog.

  • Unable to boot into 11.10 in normal (get a black screen) OR recovery (get just a flashing cursor, no cli)

    - by user1092284
    Okay, so I had a dual boot of Tango Studio (based on Ubuntu 10.04) and Windows XP. Yesterday I downloaded the .iso for Ubuntu 11.10 and attempted to install from a USB (my BIOS won't normally boot from USB but I had PLOP boot manager on a CD). I booted up Ubuntu from the USB and then from there formatted the partition with Tango on and installed Ubuntu 11.10. On booting up I came into Grub rescue mode. So I booted up from the USB again and used boot-repair to reinstall Grub. After this I would see the normal Grub menu, but on choosing Ubuntu I would come to a black screen. On choosing recovery mode it would begin starting normally with no obvious errors but instead of coming to a cli I would just get a blank screen with a flashing cursor on the top left, not accepting any input. I have since reformatted and reinstalled from a CD rather than USB and had the exact same problem. I used boot-repair again and the result is the same. Output of the most recent boot-repair is at http://paste.ubuntu.com/869805/ I have also tried editing the ubuntu grub entry and replacing quiet with text nomodeset as I saw in an answer to another question. This got me a bit further - I saw the purple ubuntu loading screen but still came to a blank screen after that. Anyway, in most of the other questions in which that is brought up the user is still able to boot into recovery, while I am not. Can anyone help? Thanks in advance, let me know if there's any more info I need to provide! EDIT FOR MORE INFO: I read something saying it's quiet splash that should be replaced with nomodeset. Earlier I had left splash in the line. So i tried it this way and it froze after displaying the following text: fsck from util-linux 2.19.1 mountall: Plymouth command failed mountall: Disconnected from Plymouth /dev/sda5:clean, 139359/1741488 files, 745830/6961125 blocks From a bit of googling it doesn't look like plymouth is essential, but I've checked and I do have the most current versions of mountall and plymouth installed so I don't know why there's a problem EDIT FOR MORE INFO AGAIN: I used dkpg --reconfigure plymouth cause I saw it mentioned in another forum and it still says plymouth command failed on boot

  • Boot error aftter clean Ubuntu 13.04 install: [Reboot and select proper boot device]

    - by IcarusNM
    I am having the same problem as this guy where a fresh Ubuntu install completes beautifully but will not boot. I get the ASUS (?) "Reboot and select proper boot device" error, first with Xubuntu 13.10 and after finally giving up there, and Xubuntu 13.4, I am back to regular Ubuntu 13.4. ASUS motherboard Z77, Intel chipset. Standard internal SATA 500GB HD. 64-bit. All-new hardware less than 3 months old. It was running Ubuntu 12.04LTC great until I tried this upgrade. I have re-installed from scratch every which way: with LVM, without LVM; with the default partitions, with my own partitions. With ext3 or ext4. Alongside; replace; upgrade. No difference. On the last two tries, I have booted afterward from the same USB stick, downloaded and run boot-repair, and now I guess I am off to the boot-repair support email with my URLs from that. It did all kinds of cool stuff but ultimately made no difference. I never got anything like this with Ubuntu 12.04. I've now probably re-installed Ubuntu 13.04 ten times slightly different ways. I finally found how to skip the language packs, so at least that sped things up! :) This starts from the ubuntu-13.04-desktop-amd64.iso and UNetbootin as suggested on the official instructions for USB thumb drive creation from OSX. That part all works fine (booting the USB on the PC and trying Ubuntu and/or installing from there on the PC HD.) I have no CD drive on this PC, but I suppose I could get one. I would rather find some Linux install that works from USB like I've always done. After running boot-repair twice, in the ASUS BIOS I now see three different UEFI boot options in the priority list, and they are all labeled exactly the same: ubuntu (P6: WDC WD5000AAKX-00U6AA0) Then there's a non-UEFI option: P6: WDC WD5000AAKX-00U6AA0 (476940MB) And a fifth option appeared after the first boot-repair: Windows Boot Manager (P6: WDC WD5000AAKX-00U6AA0) I have tried all 5 of these, and I get exactly the same error. I have never had Windows installed on this HD. ASUS is calling it Windows Boot Manaer but I presume that's a mistaken label for whatever boot-repair did. I can boot on USB and run GParted and it looks great. The partitions all look normal. I found another case of this online with no solution posted. I can't find much about it online. Needs a Master Boot Record wipe/redo?? I'm not sure how.

  • Multiple Problems Installing 12.04, now can't use Windows

    - by user87997
    First I tried using the 32-bit wubi.exe installer from the main Ubuntu website. It worked fine, dual booted with Windows 7 and all. I tried installing several applications and got errors. After searching for a little while for a fix, I found that someone else had solved the problem by uninstalling the 32-bit version and installing 64-bit Ubuntu. Apparently there is no wubi.exe installer for the 64-bit version, so I used LinuxLive to put the iso file onto a USB drive. I changed my the boot order in BIOS to check the USB first. It did, and I got into the Ubuntu installer just fine. Everything was working fine, but then I got an error that GRUB could not be installed. I chose "install manually later" or something like that. Immediately, the installer said it was done and ready for a reboot. At this point, my USB is still in the computer. The computer reboots...and it's back at the installer for the USB. I look up what's going on here, and someone says in a thread they solved it by selecting "Try Ubuntu" then installing it via a shortcut on the desktop. I assumed that Ubuntu simply hadn't installed and it would be safe to try again, so I did. It finished installing, this time I chose a different partition that wasn't being used. The thread also said to reinstall grub to the mounted drive, so I did that. Next I took out my USB and rebooted. I get stuck on the GRUB GNU loader, v.1.99 or something I believe it says at the top. I can't do anything, and it doesn't detect Windows 7 OR Ubuntu. When I check partitions, I have two 43 GB partitions that both have the same files in them (I'm assuming those are the two Ubuntu installations), and can only run Ubuntu off of my USB-- and can't run Windows 7 at all, however from within Ubuntu the windows 7 filesystem and files can still be seen. I have no idea what to do now. I used Ubuntu in the past (9.xx) and never had these sorts of problems! Please help. And sorry for the wall of text.

  • Adding Parsekit To An Xcode Project

    - by Garry
    I am trying to add the Parsekit framework to my OSX Xcode project. I've never added a 3rd party framework before and I can't get it to work right. I dragged the included Xcode project into my 'Groups & Files' pane and chose to Add it to my project. I then dragged Parsekit.framework underneath the Link Binary With Libraries heading. Then I double-clicked my target app and added Parsekit as a Direct Dependency. I also added libicucore.dylib as a Linked Library (as it says to do this on their site). Finally, in the Build settings tab of my target info I set the Header Search Paths to /Users/path/to/include/directory and the Other Linker Flags to -ObjC -all_load. Running this as a debug build work fine with no errors. However, when I build my app to release and then try to run the executable created, the app fails to load with the following error message: MyApp cannot be opened because of a problem. Check with the developer to make sure myApp works with this version of Mac OS X. Here is the dump from the crash reporter: Process: MyApp [11658] Path: /Users/Garry/Programming/Xcode/Mac/MyApp/build/Release/MyApp.app/Contents/MacOS/MyApp Identifier: com.yourcompany.MyApp Version: ???

  • Smart Array P400 - Accelerator Replacement Battery Failure

    - by inflammable
    TL;DR - Is the immediate failure of a replacement battery, for a failed battery, on a battery backed accelerator for a Smart Array P400 controller a common occurrence? Or are we likely to have an storage controller with an impending and critical fault? We have a slightly confusing situation with a Smart Array P400 storage controller with the 512mb battery backed accelerator addon on an HP DL380 server. The storage controller is (afaik) running the latest firmware and driver: Model: Smart Array P400 Controller Status: OK Firmware Version: 7.24 Serial Number: *snip* Rebuild Priority: Medium Expand Priority: Medium Number Of Ports: 2 The storage diagnostic (both on the both boot-up screen for the controller and within the 'Management Homepage' and the 'HP Array Diagnostic Utility') recently starting showing the following status a fault for the battery for the accelerator: Accelerator Status: Temporarily Disabled Error Code: Cache Disabled Low Batteries Serial Number: *snip* Total Memory: 524288 KB Read Cache: 25% Write Cache: 75% Battery Status: Failed Read Errors: 0 Write Errors: 0 We replaced the battery with a new unit (a visual inspection of the P400 card showing nothing unusual) and saw the same fault - but expected this to disappear over the course of a few hours/days as it charged. This didn't happy, and the fault status remains the same as above. Given the battery is a genuine part from HP, I wouldn't have expected a replacement battery to fail straight away, or to be dead-on-arrival (is that naivety on my part?). Is the immediate failure of a replacement battery, for a failed battery, on a battery backed accelerator a common occurrence? Or are we likely to have an storage controller with an impending and critical fault? Is there any diagnostic that could tell me more about the failed battery, without cracking the server open again? Many thanks!
