• Difficulty racking Proliant G8's

  - by Systemspoet

  We're an all Proliant shop with around 50 servers, mostly DL360s and DL380, from G5's through G7's. We just got our first two G8's in and went to rack them. We were stunned to find out that the new cable management arms protrude almost 1 inch deeper into the rack then previous iterations of the Proliant line. Unfortunately that causes them to occupy the same space as the PDU's in our APC racks. In a non-densely populated section of rack that's no biggie, but in a densely populated section it's impossible to get the cable arm into place without dislodging another machine's power. Has anyone else run into this? Obviously racking machines without cable management arms is not an option. I supposed we could reconfigure our racks but that's a nightmare.

• "Disk Not Found" Error when trying to install iso image of CentOs on ESXI using VSphere

  - by kamal

  When trying to install CentOs setup as an iso image on datastore, i get an error : "Disk Not Found". I am using ESXi 4.1 as host VM. Is there a way to attach DVD/CD as iso image ? I tried "Connect at Power on" Checked and Connect CD/DVD on the VSphere Console, but i still am unable ot get the iso image recognized as a DVD mounted image: Solved: if i look at the image size, it was 11 MB, so it WAS a boot iso, but nithing else, if we compare it with other boot images with complete iso's therein lies the solution. This boot.iso was from rBUILD/Conary packaging

• Problem accessing MICROSOFT##SSEE database (Error: 18456, Severity: 14, State: 16.)

  - by Philipp Schmid

  After an unexpected server shutdown due to a power failure, I can no longer connect to the internal windows database MICROSOFT##SSEE which is hosting Central Admin for my SBS 2008 server. The log shows: Error: 18456, Severity: 14, State: 16. Login failed for user 'NT AUTHORITY\NETWORK SERVICE'. [CLIENT: <named pipe>] I've tried to connect using the SQL Management studio (connecting to .pipemssql$microsoft##sseesqlquery) but no luck. The SQL Server Configuration Manager doesn't show a entry for 'Protocols for MICROSOFT##SSEE' (but shows it for 2 other database hosted on the same SQL server 2005 Express edition. I have tried to restore the master.ldf and mastlog.log files from a backup, but the issue persists.

• changing filesystem format from jfx to ext4 without losing data

  - by A.Rashad

  I have a fresh Lucid Lynx (Ubuntu 10.04) running on a laptop. where I defined the filesystems as: mount point / on ext4 (46 Gb) mount point /home on jfs (63 GB) swap as 3 Gb I left the machine over night to do some task, without AC power supply. next day in the morning I found it on standby, task completed, but filesystem was not reachable. it gave me I/O error it seems that there is a problem with jfs and standby. anyways, to avoid any hassle, I want to move this mount point from jfs format to ext4. can I do this without losing data and without the need to place the data in a temporary location until transformation is done? sorry to mention that, but I recall back in the windows days, we would change a FAT16 to FAT32 or a FAT32 to NTFS without having to lose the data. I hope this is available on Linux.

• Android tethering via bluetooth keeps disconnecting

  - by Ian

  I'm currently using a Google Nexus tablet tethered via Bluetooth to a Samsung S3 for internet. Two things are annoying me. First, if I take the phone away from the tablet (go out for lunch), the tablet disconnects and has to be manually reconnected. Is there a way to have that happen automatically? Second, Bluetooth tethering, i.e. the internet sharing part needs to be switched on each time the bluetooth is switched on (or perhaps just after power cycling) on the S3. Is there no way to have that default to on? Thanks

• Windows 7 x64 Hard Freezing (again)

  - by Lanissum

  Awhile ago, my computer was randomly freezing a few minutes after booting, and I ended up replacing the CPU and mobo after testing the RAM and hard drive, I also couldn't find anything wrong with the video card. So after replacing the presumably faulty hardware, everything worked fine for about a month and a half. All of a sudden, My computer is randomly freezing a few minutes after loading up any intensive application (games, mostly). Most of the time it just freezes with the current frame until I hard reset, although once it printed a BSOD message stating that dxgmms1.sys was to blame. The only difference between these two episodes I can think of is that I can do word/internet/work without issue now, as opposed to the near uselessness my computer was rendered last time. For those of you who want to know, I tested my memory with memtest86 (for 64 bit machines). I can't figure out what could have started this latest round of issues, the event logger just states that a kernel-power event has occurred (like last time) but I think thats just a generic "this machine has rebooted after a sudden shutdown" message.

• Any experience with SATA SAS Interposer Cards?

  - by korkman

  Driven by the current price difference between SATA and SAS disks on one side and the potentially bad behaviour of SATA disks in bigger storage arrays on the other side, I have found so-called SATA-to-SAS interposer cards. Advertised as "seamlessly adding SAS capabilities to existing SATA disk drives", I wonder if anyone here has had some experience with these or similar products. The major benefits I can identify are the increased cable voltage (if all drives are SAS connected), the ability to power-cycle the drive and multipath (if desired). Obviously the SATA drive will still have to be RAID edition. The question is: Do these cards indeed increase the overall reliability of a storage system, or will failing SATA disks cause trouble nevertheless? Edit: I'm not asking for hypothetical answers, only actual experience please. I'm well aware that the typical 10k SAS drive is more reliable (and better performing) than 7200 SATA drives. But how does a nearline SAS, which is phyiscally the same disk as its SATA counterpart, compare to the SATA version with interposer?

• Wake up my company computer from a home computer

  - by Darcy

  I would like to learn if it is possible for me to send a packet (a magical one) from another computer to my computer. I am interested in waking up my computer at work from the one I am using at home. That is I would like to power it on at 7:00am by sending it a wake-on packet from the home computer. I have no idea how to carry out this seemingly trivial task, I hope someone could offer some basic ideas for me start. Thank you so much in advance.

• What type of amazon instance should I use and do I need auto scaling and load balancing?

  - by Navetz

  Hi I am looking to release a website that will initially have large amounts of uploads from users. The first will be 65GB and the rest will probably be close to 1TB. They could happen simultaneously. My question is what type of amazon server instance would be best for this? The website is just being released so the traffic wont be very high. I have been using a micro instance for development but it is time to launch and I need more power. Should I use auto scaling and a load balancer to increase the number of instances when I need it or Will a small or medium instance do the trick? If I do use auto scaling and load balancing how do I handle things like sessions and the database/file lookups? Does one instance become the primary instance and the rest become clones?

• Macbook superdrive got calibration problems

  - by Fractal

  I have an intel macbook dual 2Ghz, bought about three years ago. I've had some problems with the superdrive and changed it a year and a half ago. the drive is Matshita DVD-R UJ 857 now I'm into burning cd's again and try to burn a DVD with Toast Titanium from an .iso on my hard drive But it won't work. When I launch the burn, the disc suddenly stops turning, and an error log pops: medium error, sense code = 0x73, 0x03 then I try with the built in cd burner of the macbook as soon as I click burn, the cd stops turning in the drive, and error log says peripheral couldn't calibrate power of the laser required for medium so since I'm not that logical of a geek, I try my first idea: let's see with other brands of DVD! the problem is that it works, now. but I'd like for all of my medium to be usable, and I've already seen my ridata DVD being burn, so here's the question. What the hell is happening with my superdrive? :)

• Looking for a router with multiple WAN ports and load balancing

  - by Cyrcle

  I'm going to be moving in a few months. The location I'm moving to is great except it's on a road with very few people, so the internet access option is limited to DSL at 1.6Mbps down, 384kbps up. This is much slower than I'm used to. One option is to get at least two of the DSL lines. There's also good possibility that I'll be able to get WiMax or similar. I've been looking around a bit and it seems like what I need is a load balancing router with multiple WAN ports. Can anyone recommend some good ones? I could also go with a small power efficient Linux box with multiple NICs. What would be good software for that? It'd need to be able to handle around 10Mbps. Thanks for any help

• How can I determine what is causing SQL Server 2008 Express to hang Windows 7?

  - by thelaughingdm

  I have SQL Server Express 2008 installed on a Windows 7 (32-bit) developer workstation. Whenever I run an application that accesses SQL Server the Windows 7 shell hangs when the application closes. Applications like Windows Explorer and Task Manager become completely unresponsive. The task bar will not allow any interaction. The only way to recover the system is to power cycle. Two of the applications in use when this happens are NUnit and SQL Server Management Studio. NUnit always runs the unit tests that interact with the database fine. SQL Server Management Studio will sometimes cause the problem while trying to explore the database. The Windows event log does not show any events that are obviously connected to the problem. I have reverted and reinstalled SQL Server Express 2008 several times. What can be done to identify what is causing SQL Server Express 2008 to hang the Windows 7 shell?

• Ubuntu 11.04 hangs at "checking battery state" while booting

  - by MisterSir

  When I try to boot Ubuntu 11.04, it just hangs when it gets to checking battery state. I know this issue is usually related to graphic drivers, but it worked like a charm for months now. Last time I was on Ubuntu I updated my system with the update manager, so maybe an update caused it. Anyway, I really need Ubuntu. I'm in the middle of work on a website and I have a deadline, so I need some help over here. Thanks. p.s. I tried reinstalling gnome-power-manager. Didn't work. And I'm not on a laptop.

• Sharepoint insists it knows the link to my UNC and won't let me remove hyperlink formatting

  - by ray023

  We have a file share at work (one I do not have the power to rename) and it contains a space in it: \\WorkFileShare\Visual Studio\SP1 I'm creating a Wiki Entry that informs users they can locate the VS2010 SP1 download on this Share. For some reason, SharePoint will highlight and hyperlink the UNC up to the space. (I've been dealing with this behavior for years in Outlook and I fix by putting focus on the character before the space and then hitting backspace to remove the formatting). Simple enough and SharePoint also removes the formatting when you backspace on the character before the space. However, as soon as I move away from the link, SharePoint goes right back to highlighting and hyperlinking what it thinks is the UNC. Naughty Sharepoint!! So does anyone have any idea how to clear the formatting? NOTE: Highlighting the text and clicking on the "Clear Format" icon does not work.

• spurious hardware memory 'errors' on hp dl380 g5's being generated

  - by friedchicken

  Hi All, i've got 2 new HP dl380g5 servers running HP's esxi4 patched to 219382. they have both been patched up to the latest hp firmware levels (firmware cd 8.7) both are running 32gb (4 x 8gb sticks) both servers are showing the same symptoms - the memory lights come on for two (random) dimms on the front of the server and the health led turns red. sometimes the server stays up and running with no problems. othertimes the server locks dead and only a power reset can bring it back. there is nothing showing in the ilo logs and nothing within the vmware hardware monitoring. the memory has been replaced i've got other customers that have been running dl380g5's with out any issues on esx3.5 - this is our first vsphere deployment with them. these are meant to go live soon so any advice would be great. thanks in advance.

• How do I pick a motherboard?

  - by EpsilonVector

  When building your own computer one part was always a mystery to me: the motherboard. Picking a CPU/GPU/memory is easy- you just figure out where the various chips are in the low end to high end scale, do a little market research on what current games demand, and pick the parts from their respective continuums of low-to-high-end models. A mother board is more complicated though. Its features are not as obvious as "this motherboard is faster than that motherboard". Now you need to deal with part compatibilities, bus speeds, maybe power management stuff, etc. I'm interested in a short guide for selecting a motherboard, especially- what pitfalls to avoid (for example, can bus speed become a bottleneck?). To clarify: I'm not looking for motherboard recommendations. I'm looking for guidance regarding how to evaluate the fitness of a motherboard given the rest of the computer parts.

• What does an ACPI BIOS configure during boot?

  - by RJSmith92

  When a PC boots with an ACPI BIOS, what does it exactly do? I understand that the point of ACPI is to allow the OS to control hardware resources and power management but before the OS is loaded does ACPI configure just the devices needed to boot and then let the OS configure the rest? If the OS wants to re-asign hardware resources does it store this information in the ACPI tables so that the next time the system is booted it assigns them how the OS wants? The ACPI driver asks the PCI bus driver (Pci.sys) to enumerate devices on it's bus once the OS is loaded, how are these devices configured whilst the PC is booting when it doesn't have other bus drivers? Any help with any of the above questions would be greatly appreciated. Thanks.

• Ubuntu 9.10 freezes when HDMI port is connected

  - by Felipe Hummel

  Hi, I have a Sony Vaio FW350 with a HDMI output. I'm trying to use it under Ubuntu 9.10 with a LG LCD monitor 21,5'. I've tried two approaches: Boot the laptop with the HDMI cable connected and monitor turned on. Result: LCD Monitor keeps turned on but the whole screen is black and Ubuntu do not seem to be initializing. Boot Ubuntu until the end. I then connect the HDMI cable into the Laptop. The mouse and the whole system freezes. In both cases the only way to turn off the laptop is holding the power button. I've looked around the internet for similar problems, but only found workarounds for the same problem with VGA input, not HDMI. I also tried to use metacity before connecting the cable, but still got the same result. Any hints?

• automated printouts from a wireless printer

  - by Piotr

  I have a wireless printer which is always on, and an always on fanless linux server. Looking at the mprinter project on Kickstarter I started to wonder if there is an app somewhere in the internet already that will allow to prepare an automated daily printout based on some settings. things to be printed could include - weather forecast for my locations, todo`s scheduled for that day, a "quote of a day" or "word of the day", stats from google analytics for my site, and many more ... I would set a printout at 6:15 every work day so its on my printer when I am already up, having a coffee. anyone knows something that can be used for such purpose? While I know this can be done by combining the power of TeX, cron and a script language to manage the dynamic part of the PDF I believe this is a use case someone has already addressed.

• Server goes offline. What to look for?

  - by Jonathan Sampson

  I'm using a new virtual server through GoDaddy, and this morning I received a call from the powers that be informing me our website was offline. After confirming this, I requested a power cycle through our GoDaddy control panel, and within a minute or two the server was back online. I made the call, and reported the news that we're back up. Of course, a couple minutes later we're down again. I tried connecting through PuTTy, and it takes forever to prompt me for a username, and each successive prompt takes a long time to come up. I'm using CentOS. So my questions are: How can I determine the cause? What types of things can I do to prevent this in the future? One interesting, and perhaps relevant, observation is that yesterday our bandwidth consumption was about 20% greater than our top figures from the past month.

• How to set Laptop Brightness in Gnome and /proc on Thinkpad W510?

  - by hakre

  I can set the brightness of my laptop screen already via /proc. I can read and change the value. Now I've set the value to 33 and then I went into gnome power management and enabled the option that it should reduce the backlight brightness being on battery. That works, the screen gets darker. If I now read out the current setting from /proc it still says it's 33. So I assume that there is another node in /proc to be used to control the brightness. The node I use so far is: /proc/acpi/video/VID/LCD0/brightness I'm using the nouveau driver. With the nvida driver the brightness can not be controlled.

• PC powers up but there is no display

  - by Matthew

  I built a computer with standard components I bought from Newegg about three years ago. It ran great for 2 years and has sat powered down for the last year. I tried to power it up today and the display was blank. It powers up, lights come on, drives start spinning but there is nothing on the display. I verified that the monitor and video adapter work. I also tried the video adapter in a different slot on the mother board with no luck. What's the next thing I should try? Is the mother board shot? Thanks.

• Auto-connect Bluetooth headphones in Windows 7 64bit

  - by CptSkippy

  I have a pair of bluetooth headphones that I've successfully paired with my Windows 7 64bit machine and audio plays through them without a hitch. On the Device Stage under the properties of the headphones in troubleshooting it shows "last connected" as "currently connected" even if I power cycle the headphones or after a reboot of my computer. So the Windows bluetooth stack has no trouble finding them. The problem I have is that whenever the headphones reconnect to my pc they show up as disconnected in the Sound Settings and no sound is routed to them until I manually connect them. I have to go into Sound Settings, then from the Playback tab right click on the headphones and choose the Connect option. Is there a way to make the Sound Settings connect automatically whenever the headphones are available to Windows?
