• Can I flash a PCI-E device's Firmware in a VM if the VM has exclusive IOMMU access?

  - by RibaldEddie

  I have a PCI-E Dell Perc 6/i RAID card that I'd like to flash with the latest firmware. Apparently I need either a Redhat / Centos OS or Windows in order to flash the firmware, but I have a VMWare 5.0.1 ESX hypervisor installed on the box and a CentOS guest OS. My motherboard support IOMMU and I have successfully used VMWare's PCI Passthrough feature to give VMs exclusive access to a PCI-E device. Is it safe to flash the firmware of a PCI-E device if that device is passed through to a single VM using the passthrough feature of VMware? Or should I boot one of the supported OSes directly on the bare metal?

• Recover a lost IBM DS4300 SAN password?

  - by Daniel

  I have a pair of IBM DS4300 SAN units that I need to perform a firmware upgrade on. Unfortunately the admin passwords on these units have been lost and now need to be reset. I had hoped the default password of 'infiniti' would work but it seems that it must have been changed. I know the method here is to contact IBM but the cost of that phone call is ludicrous if someone out here knows what they're going to tell me to do. These units are out of warranty and the cost of support is beyond what we have the budget for. Is there an interrupt I can enter during the boot process (similar to a cisco password recovery) or is there a hardware/software tool I require? Please, if anyone has ever gone through the process of an IBM password recovery I’m asking for a little help. EDIT: Just to clarify, the password I need to reset is the one used for serial cable access and not for storage manager. Sorry if I have caused more confusion.

• debian lenny xen bridge networking problem

• Unable to resolve FQDN, hostname works

  - by HannesFostie

  We are having an issue where computers who are not part of the domain cannot resolve the FQDN of a server (but regular hostname and ip do resolve). The strange thing is that this does work when the computer is added to the network. Our domain name is rather long, its something along the lines of "team.dept.company.com", could that be it? DHCP server passes along the proper DNS, Name and WINS servers, as well as the domain name. I thought that should've solved the problem, but apparently not really. Our domain is still windows2003 EDIT: I am starting to believe I can narrow this down to a problem either with the vmware tools NIC drivers that are embedded in my winPE boot image, or to the fact that I'm trying to do this from inside a VM. Pinging a FQDN at the same time when using a different task sequence on a physical machine works.

• RHEL 5.x SCSI Driver .img update for initrd.img

  - by zmische

  I have production DB server (RHEL 5.1) with LSI Megaraid driver loaded during setup via DUD (Driver Upd Diskett). Now I'd like to update kernel and other packeges to 5.4 version. I also downloaded new LSI SCSI driver (megasr-13.11.0922.2009-1-rhel50-u4-all.img ). Could you explain the necessary steps to make this driver visible on boot for new kernel (lets assume, that I've already update kernel to 5.4)? I read the article on Redhat - "How do I add a driver to the initrd.img". Does it contain all the steps I need? Thanks in advance!

• Where Debian Lenny stores initial ifconfig values?

  - by Kuroki Kaze

  With upgrade of VMWare Player I suddenly found my Debian Lenny VM not getting IP address. Some DHCP issue maybe, I don't know. So I have to set it manually every boot in Player window, via: ifconfig eth0 down ifconfig eth0 192.168.175.128 netmask 255.255.255.0 up I usually start up VM and then connect to it via SSH, so this procedure bothers me. Sure I can add it to startup script, but is there some special place to enter these values? Like, some config file or so?

• Entering BIOs Setup from Supermicro IPMI KVM

  - by Joshua Lim

  I'm having trouble getting into BIOs Setup from Supermicro IPMI "KVM" - Remote Control Console Redirection. I need to change the boot order to CDROM first. I'm running Windows 2008 server. After some Googling, it says here that the method is to: Press TAB to enter Setup screen. Press Esc twice to take effect. http://www.supermicro.com/support/faqs/faq.cfm?faq=6222 A month ago, I tried that 30-40 times + DEL, over 2 hours, it worked. Now, I've been trying the same key combination for more than an hour, rebooting each time it failed, it still doesn't work. Note: I've only got a notebook computer, no extra monitor.

• SATA 300 mobo and drives but only connected at SATA 150

  - by Shevek

  I have an Abit AB9 QuadGT motherboard which supports SATA 300 drives Connected to it I have a Kingston SSDNow V Series 64GB as boot drive and a Seagate Barracuda 7200.10 as a data drive. I also have 2 x Optiarc AD-7170S DVD burners attached by SATA Both SSD and HDD are SATA 300 and the optical drives are SATA 150 I have just run CrystalDiskInfo and this is reporting that both SSD and HDD are connected at SATA 150, not SATA 300. I have the BIOS set up to use SATA drives in IDE mode. So a few questions: Is CrystalDiskInfo reporting correctly? Are the optical drives causing the SSD & HDD to connect at the slower rate? Is there any setting to force the SSD & HDD to use SATA 300? I'm running Windows 7 Ultimate

• Windows 7 64 Bit Can't Get Past Format

  - by Soren

  favorite Just assembled a new machine: MSI 880GM-E41 motherboard 500GB Samsung hard drive AMD Athlon II X4 640 processor 4GB RAM Windows 7 64 Bit LITE-ON Black 4X Blu-ray reader I boot up, start the install. When it gets to the screen to select what partition, the motherboard loses power. It doesnt make sense, I can leave it in the bios settings for a very long time and it doesnt lose power. When it does lose power, the monitor shuts down and the mouse loses power, but the power light stays on. I cannot tell if it is a harware or software problem.

• How to roll-your-own live CD for safe home browsing

  - by user36533

  Hi, I'm interested in booting-off-flash (i.e. like livecd) for more secure online banking at home. -I like system rescue CD, but AFAIK it doesn't have the wifi drivers. (These are convenient) -ubuntu live cd has the wi-fi drivers, but also has a lot of stuff I don't need -I'd like a way to save some basic config settings (e.g. wifi SSID and passphrase), so that wifi works upon startup, i.e. without having to re-enter the settings. What's the best way to 'roll my own slightly-customized boot-from-flash live cd? thanks, bill

• Free space not reclaimed after online resizing ext4 in Ubuntu 9.10

  - by TiansHUo

  My root partition was filling up, with only 500 mbs left, I wanted to resize my root partition from 20 Gb to 40Gb So I resized my partition by using these steps: Using Gparted to resize another partition to give space for the EXT4 Using fdisk, deleting the root partition (on /dev/sda2), and creating it again using the new size resize2fs /dev/sda2 Updating grub2 But now the problem is that although I can boot in my new partition and the new partition shows it is 40Gb, but the free size was still 500mb. So I booted from a LiveCD and checked with e2fsck -p /dev/sda2, it reported clean. So I added the -f flag (force check), still, the drive is full.

• Windows Explorer is blank

  - by Scott Mitchell

  I am using Windows 7 Utlimate x64. Once a week, or so, when I boot up n the morning and launch Windows Explorer it shows up blank, as the following screen shot show. Clicking on my Computer doesn't load anything. Interestingly, I can go the the Address bar at the top and type in a folder name. This brings up that folder's files and subfolders, but as I drill around the tree of folders on the left only shows the immediate folder and not its siblings. There's no plus icon to expand the folder, etc. My usual "solution" is to reboot, which typically brings everything back to normal, but this is a frustrating remedy. Any idea what's going on and how to fix it? Some Googling turned up this discussion, but the remedy was to uninstall a particular piece of software that I don't have installed (Virtual Clone Drive). Thanks

• Dell R610 memory configuration for all 12 slots

  - by Neal

  I purchased 12 sticks of RAM on eBay to go into a Dell R610 server. The RAM is ECC REG PC3-12800 DDR3-1600 yet when I occupy all 12 slots with this ram I get the following error on boot: MEMORY Initialization Warning: Memory Size May be Reduced MEMBIST failure – The following DIMM has been disabled by Bios: DIMM B2 MEMBIST failure – The following DIMM has been disabled by Bios: DIMM B5 I am using all of the latest versions, BIOS, etc. I am using 2 x x5660 processors. What is causing this issue and is it correctable? If this RAM is incorrect what is correct to maximize the RAM on this server? Thank you.

• Changing Windows Media Center StartRecording Task Scheduler options

  - by T Reddy

  Hi, I'm experiencing some occasional crashes waking from sleep and I believe it may be related to the Corsair SSD F40GB2 as my boot disk...or the new Ceton tuner I recently installed... I dunno what the real problem is as I can't reproduce the problem manually. I read somewhere that I should not allow the hard disks to sleep...so I'm trying that in the meantime... At any rate, I don't really care that the computer crashes so long as WMC will start recording the task as soon as possible...the task is scheduled to wake the computer 5 minutes before the recording starts. I noticed that there is a StartRecording param in the Media Center folder in Task Scheduler. There is an option (currently unchecked) that will retry a failed task. I would like to know if there is a way to enable that checkbox. My hope is that if my PC crashes when waking up for this task, that after it reboots the task will trigger again and start recording. Thanks!

• HP ML350G6 running hyper-V 2008 r2 resets itself every 2 hours

  - by GT

  The system started resetting itself exactly every 2 hours. These are the messages in the iLO2 log: Informational iLO 2 03/07/2010 20:40 03/07/2010 20:40 1 Server power restored. Caution iLO 2 03/07/2010 20:40 03/07/2010 20:40 1 Server reset. It's not an ASR reset (that would show in the log) Redundant power supplies, swapped but no change. Turned off all virtual machines (i.e. now only running hypervisor) but not OK Boot HP smartstart diagnostics disk, ALL OK Diagnostic disk reports no errors Went back to booting Hypervisor and the problem is back. Seems the hyper-V system disk has got a time based program (virus) causing the reset. I thought the hypervisor had a small attack surface and should be OK. All virtual machines (SBS2008, Win7 and Win XP) and network computers are protected with TrendMicro WFBS. I am about to rebuild the disk (I have backups) but wondered if there were any suggestions to try first???

• Windows explorer locks files

  - by John Prince

  I'm using Office 2010 & Windows 7 Home Premium 64-bit. My problem starts when I attempt to save e-mail messages to my PC that I have received via Outlook (my ISP is Comcast). I'm using the default .msg file extension option when I attempt to save these e-mails. The resultant files are locked and do not show the normal "envelope" icon. Instead, it’s a “blank page” icon with the right upper corner folded in. These files refuse to open either by double clicking on them or right clicking and trying to open them with Outlook. And when I return to Outlook, I discover that Outlook is now hung up and I have to close it via the Task Manager. To make matters worse, I’ve also discovered that every e-mail message that I've saved on my PC over the years has also somehow become locked and their original "envelope" icon has been replaced with the "blank page" icon. I found and installed an application called LockHunter. As a result, when I right click on a saved and locked e-mail message, I’ve given an option to find out what's locking it. Each time I'm told that the culprit is Windows explorer.exe. When I unlock the file the normal envelope icon is sometimes displayed (but not always) but at least the file can then be opened. But the file is still “squirrely” as it can’t be moved or saved to a folder until it’s unlocked again. On this second attempt, LockHunter says it’s now locked by Outlook.exe. By the way, I don't have this issue when I save Word, Excel & PowerPoint files; only with Outlook. I've exhausted every remedy that I can think of including: making sure that the file and folder options are checked to always show icons and not thumbnails; running the Windows 7 & Office 2010 repair options which find nothing amiss; running a complete system scan with Windows Malicious Software Removal Tool with negative results; verifying that Outlook is the default for opening e-mails; updating all of my applications via Secunia Personal Software Inspector; uninstalling every application that I felt was unnecessary; doing a registry cleanup via CC Cleaner; having Windows Security Essentials always on (it did find one Java Trojan recently which was quarantined and then deleted); uninstalling a bunch of non-Microsoft shell extensions; and deactivating all of the Outlook Add-ins and then re-activating each one. None of this solves the problem. I’d welcome any advice on how to resolve this.

• Error codes 80070490 and 8024200D in Windows Update

  - by Sammy

  How do get past these stupid errors? The way I have set things up is that Windows Update tells me when there are new updates available and then I review them before installing them. Yesterday it told me that there were 11 new updates. So I reviewed them and I saw that about half of them were security updates for Vista x64 and .NET Framework 2.0 SP2, and half of them were just regular updates for Vista x64. I checked them all and hit the Install button. It seemed to work at first, updates were being downloaded and installed, but then at update 11 of 11 total it got stuck and gave me the two error codes you see in the title. Here are some screenshots to give you an idea of what it looks like. This is what it looks like when it presents the updates to me. This is how it looks like when the installation fails. I'm not sure if you're gonna see this very well but these are the updates it's trying to install. Update: This is on Windows Vista Ultimate 64-bit with integrated SP2, installed only two weeks ago on 2012-10-02. Aside from this, the install is working flawlessly. I have not done any major changes to the system like installing new devices or drivers. What I have tried so far: - I tried installing the System Update Readiness Tool (the correct one for Vista x64) from Microsoft. This did not solve the issue. Microsoft resource links: Solutions to 80070490 Windows Update error 80070490 System Update Readiness Tool fixes Windows Update errors in Windows 7, Windows Vista, Windows Server 2008 R2, and Windows Server 2008 Solutions to 8024200D: Windows Update error 8024200d Essentially both solutions tell you to install the System Update Readiness Tool for your system. As I have done so and it didn't solve the problem the next step would be to try to repair Windows. Before I do that, is there anything else I can try? Microsoft automatic troubleshooter If I click the automatic troubleshooter link available on the solution web page above it directs me to download a file called windowsupdate.diagcab. But after download this file is not associated to any Windows program. Is this the so called Microsoft Fix It program? It doesn't have its icon, it's just blank file. Does it need to be associated? And to what Windows program?

• Late 2008 Unibody MacBook Pro, Snow Leopard EFI 1.8 downgrade

  - by SiLo

  Question: Does anyone know of an EFI downgrade for user on 1.8? I have found a 1.7 to 1.6 downgrade, but once on 1.8 this downgrade no longer works. Background: After upgrading to Snow Leopard, and installing the EFI 1.8 update (as recommended by Software Update), I have lost the ability to burn discs. This also includes when using external burners and when booting into Vista using Bootcamp. Other seemingly related problems to the EFI I have are, chronic overheating, random temporary beachball lockups, longer boot times. These 'other' problems have been solved for other users who experienced these problems on EFI 1.7, but were able to rollback to 1.6. I am looking for a solution that does not require sending my computer back to Apple.

• sudo: must be setuid root

  - by Phuong Nguyen

  Recently, due to some messy stuff with master boot record, I have to re-install my Ubuntu. Before doing that, I back up all folder (exclude root, bin, sbin, tmp, media, mnt) to a NTFS partition. After installation of Ubuntu, I copied back all the folder using a nautilus (running by sudo nautilus). After that, I reboot my computer. And boom, now I cannot run sudo any more, my network services cannot run. When I run sudo from a terminal, I ge "must be setuid root" error. In ubuntu, root account is disabled by default, I don't know why all these files is no longer under ownership of my account. How would I recover back?

• Samsung 530U3C clean system installation

  - by user1292810

  I have bought Samsung 530U3C notebook with i5-3317/12GB RAM/500GB HDD/24GB ExpressCache/Windows 8 preinstalled. I would like to install my own clean version of Win8. But I would like to preserve recovery partition. I will sell this laptop in probably 1-1.5 year and I would like to be able to restore settings to factory ones. What is more, in the future I would like to install Ubuntu as well, but Windows goes first. At the moment discs and partitions looks like below (sorry for non English screen): http://i.stack.imgur.com/p4W6t.jpg DISC 0: 500MB - recovery partition 300MB - system partition 442.22GB - Drive C: - Boot, Page File, Crash Dump, Primary partition 21.64GB - recovery partition 1.00GB - recovery partition DISC 1: 9.00GB - primary partition 13.24GB - primary partition Which partitions can I format and which of them should I preserve? Can I format and merge partitions from that 24GB ExpressCache and install Windows on it?

• Symmetrix gatekeepers on Solaris 10

  - by Milner

  I have some Solaris machines that are connected to EMC Symmetrix for SAN storage. Apparently the Symm has a gatekeeper device that is used with the symmetrix CLI. We don't need the CLI, but I have these gatekeeper devices that constantly fill /var/adm/messages and the like with corrupt label errors. Is there anything I can do (short of deleting the devices on machine start) to get rid of them? Or should I just try to get our SAN guy to get the installer for the CLI? These things are getting annoying, and the devfsadmd daemon keeps rediscovering them on boot.

• How should i setup my PC partition?

  - by acidzombie24

  I want to clear out my PC and setup the partitions. Right now i have it as XP, Win-7, Vista, XP/Test/Spare I notice my PC is pretty good at virtualization, at least virtualizing linux. I also rarely boot out of my primary XP although i do find myself deving on windows 7 once in a while. So i figure i can have it as XP, Windows 7, data partition then... what? i still have one more slot. There may be a more useful way to do this so what do you guys think? My bro has 2gb partition that is used to restore the OS which can be ran during the bootup process. However i dont think i can do that with mine. So, what are you thoughts?

• Locate rogue DHCP server

  I know this is a serious long shot, but here we go. In the past week or so, for users connected to a particular switch in our network (there are four dumb switches all connected, and it only affects SOME, not all, users on the one switch) are getting DHCP addresses from a rogue DHCP server.

I know the IP of the DHCP server, but I cannot ping it, and it does not have a web interface. Does anyone have any suggestions on what I can do to locate it or shut it down? Unfortuantely all the switches are unmanaged, and as mentioned, there's no physical device (that I can find) plugged in to anything. It's getting critical, because it's screwing up the PXE boot of a whole bunch of thin clients.
