ESXi SCSI 5 to "cannot get disk partition information.

Off I must first say that I have tried to follow the guides as much as I could find to solve this problem, but nothing has worked.

We have a server with a single 130 GB drive that ESXi 4.0 resides on and another disk SCSI 5 to that we wanted to use as a VMFS partitioned drive, with a big VMDK, who accesses our Server VM file.

ESXi installation went well, however, when we arrived to add the second drive as another data store, we got an error message: "error during the configuration of the host: could not get disk partition information. From there on, we tried several solution, manually formatting the drive with the tools of command line vmkfs, Re-partitioning for ext2 with GParted Live, erasing information from partition with dd, deleting all partitions, all without success.

We are posting our problem here as a last resort, I can confirm that vSphere displays the total capacity of the car, but not the partition information. It seems also a gap between the capacity of disk fdisk reports and esxcfg-scsidevs - l capacity.

Here are a few out of order, it was after the partitions have been deleted on 5 TB disk (the one that ends with "67"):

I had heard he had some problems with the help of 2 TB disks in ESXi, however I was not sure if it was directly relevant to this problem. I am open to using Raw Device Mappings, I think I've seen a few guides on the methods not supported for adding THAT RDM on a local drive - all advice on this would be welcome.

Currently, we hold a store of data from 5 to and VMDK join one of our virtual machines. I guess my question is: How can I get the 5 TB drive work in ESXi?

Hello and welcome to the forums.

ESX (i) can be used to the maximum 2 TB - 512 bytes to the size of the LUN.  It is documented in KB 3371739.  You can just cut up this 5 TB drive into partitions smaller than 2 TB - 512 bytes each.

Good luck!

  • trying to create an ESXi data store on the local drive.  Configuring the host error: unable to update the disk partition information

    I'm a newbie on ESXi and don't know what it takes to get ESXi correctly partition my drive SATA 500 correctly.

    I will implement a laboratory unit to carry out tests for ESXi and ESXi is not quite correctly the disk partitioning or do not see a good partition in order to create a data store.

    This system was able to correctly identify and configure a data store on a small 80 GB seagate SATA disk, however, this isn't quite enough storage so I swapped the hard drive and tried to re - install ESXi on the new hd.

    I use a USB boot ESXi since and it is launched and configures the card intel pro1000 pci ethernet correctly.  also correctly the id of the cpu and memory.  everything seems fine and he is even able to see the hard drive.

    Here are some screenshots of the process that I go through to make my data store...

    on this photo-sous the column titled 'available' is 'none', also said, under the title 'san identifier' he said 'not applicable' - I guess that's not quite right?

    and disappointment - failure?

    I tried to go into the bios if there are some settings I need to do to get this hard drive set up... I don't understand enough about ESXi to find out why the drive is not found and configured correctly.  is this a bios problem w / my system or a problem of ESXi?

    pls help!

    You have generally not, but it might be interesting to start with something like a Linux live CD and then using gparted or other to wipe all the top partition information.

  • Failed to get the disk partition information when you add the new data store

    Hello

    Update my ESX to version 4 Update 1 (4.0.0, 256968). Now, I'm trying to add a new data store to a cluster in vCenter and receive the following error message when I will review the current structure of the disc "error when configuring the host: failed to get the disk partition information. When I click back, then next, there's no error message but in the formatting window, I get the error "Object reference" not set to an instance of an object.

    I see this question has been asked before, but I can't seem to find an appropriate response. Anyone? The interface using CLI instead of vCenter isn't an option (alignment VMFS, workload and so on)

    I use Dell R900 with an EMC Symmetrix VMax SAN

    The size of the LUN I want to add is 741 GB

    Concerning

    Marius Aulie

    If you have a virtual machine for Windows test, you could do the following, to ensure that the logic unit number has a clean partition table:

    -set the LUN as a GROSS physical to virtual machine device

    -Run diskpart, select the drive and run the CLEAN command

    -detach the LUN to the virtual machine

    -try to create the data on the LUN VMFS store

    The size of the block of the data store where the VM test can be a problem with the above. Due to the size of the LUN, the size of the block of the data store must be at least 4 MB. Attach the LUN to a physical test system could be an alternative.

  • Tecra M10 - 11U - DVD + cannot read & disk partitions

    Hi all

    I just got my new Tecra M10 - 11U and noticed 2 things troubling
    (1) my DVD cannot read DVD + R - Vista recognized the DVD and its type, but cannot open it. Ideas?
    (2) my drive letters are C and E, where is my D drive, is the hidden recovery drive?
    Is it safe to change the E to D drive

    Nirko

    Hello

    1. it is not easy to provide a response to this. The question is rather general and who knows what kind of things is on this DVD + R media.
    2 D drive probably doesn t exist. You can check if the D drive letter is available for free. If so this means that this player is not available. You can check in computer management > disk management. Choose the second partition and click with the right mouse button > choose the option change the drive letter or path. You will see that D is available here.

    Recovery disk doesn t exist and it is not hidden. Toshiba recovery image is saved in the folder called HDDRecovery on the second partition.
    * You can change the drive letters, but before you do anything whatsoever, please create recovery DVD.*

  • computer windows XP won't load does not and cannot get disk recoevery to run

    After turning on my computer comes up with the Dell logo and then turns off. I tried to start in safe mode and thus to an earlier point, but nothing happens, and the processor is very quiet, so maybe it's that. My main problem is how to get all my files and folders from the hard drive...

    Hi carelesstalk,

    1. don't you make changes before the show?

    Try these steps and check the result.
    Step 1: Start the computer using the 'Enable VGA '.
    a. see the Description of the Mode of course in Windows XP startup options
    b. in the safe mode options, select "Activate the VGA Mode" and check if the computer starts.

    Step 2: If you are able to run the computer to activate the VGA Mode, then turn off the graphics card and check if the computer starts in normal mode. To do this, try the following steps:
    a. Click Start, click Run, type devmgmt.msc, and then click ok.
    b. expand display adapters, right-click on the sub element and click on disable.
    c. start the computer and check if the computer starts.

    Note: If the computer starts in normal mode, and then uninstall the video card.

    Step 3: If nothing works, then perform the repair facility using XP disk and check the result. To do this, try the following steps:
    a. start the computer using the XP CD. You may need to change the boot order in the BIOS OF THE system for the CD starts before the hard drive.
    b. on the "Welcome" screen, press ENTER to start the installation of Windows.
    c. accept the license agreement and Windows will search for existing installations of Windows.
    d. Select the XP installation you want to repair in the list, press R to start the repair.
    e. the installation program copies the necessary files to the hard disk and restart.  Do not press any key to boot from CD when the message appears. Setup will continue as if it were a clean install, but your applications and settings are preserved.
    f. when the installation is complete, check if Windows starts correctly.

    If the problem persists and you are using a desktop computer, we you recommend removing the hard drive and connect it to another computer and then back up your data.

    For further assistance, please contact Dell support.

  • Help, please! A master hard disk partition information lost and cannot start the Vista system

    I have Vista with my dell desktop computer.  I guess I got a virus that has deleted/messed my main hard drive.  All of sudden my computer was dead and when I try to restart, I found I can't boot the system.  I loaded the DVD for the resettlement of Dell to come with the computer and try to install it.  But it shows "Disk 0 unallocated space" with 222 GB and 'Disk 0 Partition 2 Recovery' with 10 GB.  I could not install Vista on the first, as it says "Windows must be installed on a partition formatted in NTFS.

    How could I solve this problem?  I could not allow me to format the drive because there a lot of data, that I just can't lose.

    Problem with the recovery process, contact Dell at the link above.

    It's recovery process from Dell, NOT Microsoft.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Try this to save your data:

    Data recovery:

    1. slave of your hard drive in another computer and read/save your data out there.

    2. put your Hard drive in a USB hard drive case, plug it into another computer and read/save from there.

    3 Alternatively, use Knoppix Live CD to recover data:

    http://www.Knopper.NET/Knoppix/index-en.html

    Download/save the file Knoppix Live CD ISO above.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    http://isorecorder.alexfeinman.com/isorecorder.htm

    Download the Vista software from the link above.

    After installing above ISO burning software, right click on the Knoppix ISO file > copy the Image to a CD.

    Knoppix is not installed on your PC; use only the resources of your PC, RAM, graphics etc.

    Change the boot order in YOUR computer/laptop to the CD/DVD Drive 1st in the boot order.

    Plug a Flash Drive/Memory Stick, BOOT with the Live CD, and you should be able to read the hard drive.

    When the desktop loads, you will see at least two drive hard icons on the desktop (one for your hard drive) and one for the USB key.

    Click on the icons of hard drive to open and to understand which drive is which.

    Click the icon for the USB drive and click on "Actions > Change the read/write mode" so you can write to disk (it is read-only by default for security reasons).

    Now to find the files you want to back up, just drag and drop them on the USB. When you're done, shut down the system and remove the USB key.

    See you soon...

  • Disk partedUtil utility command-line on ESXi disk partitioning

    Hi all

    I created the partition by using the utiliy of command-line partedUtil on ESXI in the face of error below:


    • error: "Invalid guid (0xfb). Contains non hexadecimal numbers
    • Is not a valid guid (fb). Length should be 32
    • Is not a valid guid (251). Length should be 32

    Can you advise me how to solve the problem of the partition.

    Hi Prashant.

    VMFS data warehouses can be created and deleted using the vSphere client connected to an ESXi/ESX host or vCenter Server. It is not necessary to manually create partitions by using the command line utility. For more information, see the Configuration Guide for your version of ESXi/ESX storage management.

    Resolution

    You can use the partedUtil command line utility to directly manipulate local and remote tables of partitions on the disks of SAN on ESX and ESXi.

    The partedUtil command-line is only supported for ESXi 5.x disk partitioning. The command-line utility fdisk does not work with LUN formatted with VMFS5.

    Note: This article is from the principle that a console session is available to the host ESX or ESXi, you're familiar with console management concepts and the disk, and you did backups appropriate before proceeding. For more information, see:

    Unable to connect to a host ESX using Secure Shell (SSH) (1003807) or

    Using the Mode of Support Tech in ESXi 4.1 and 5.x ESXi (1017910).

    If you are not sure of any step, contact the VMware Support.

    For more information on the re-creation of a missing VMFS partition table using PartedUtil see: re-creating a VMFS datastore partition missing in vSphere 5 (2046610)

  • disk partition utility grey buttons

    The new disk in el capitan utility is driving me crazy.

    To begin with why I can't partition during erasure.  Where is this option.

    I was able to partition a USB once but I can just manage to do it again.

    In the partition screen the + and - buttons are dimmed and I can't fill anything in the size field.  When I go to different Formats al of a sudden field size is editable, but you enter a value doesn't change anything.

    The thing is I managed to do it before (just before the 10.11.2 update), but he was also extremely heavy.

    in any case really start silike Mac OS more, things that when easy are getting harder with all versions.  Good example of all leave well enough alone or better get tested.

    They have changed the functioning of a disk utility and not necessarily for the better.
    Firstly, you must first clear a new drive to format before you can partition then it.

    In addition, you cannot select the partition button unless you select the entire disk, not an individual partition (even if that covers the entire disk) ve

    But more annoyingly, as far as I found (I could be wrong I guess) you can leave the part of the disk not FORMATTED. I tried to leave the space for a my Samsung 850 Evo SSD oversupply, but it automatically reformatted the remaining as a partition space if you do the first partition smaller than the size of the full disc.

  • Windows 7 Home Basic disk partition.

    Yesterday I created a disk partition in my laptop of friends using Windows 7 home basic. Now, I am unable to send it back. When I try to format it by using the default settings the error I get is. "The dynamic disk is not supported by this server." Later, I got to know that dynamic disk is not supported by Home Basic. Now what to do? I am unable to use the 150 GB partition I've done unless I format it. Is it possible that I can use this space?

    Create a separate partion to "ease the burden on partition win" is not actually going to achieve something IE doesn't go to lighten everything, leave them are part of this disk.

    I guess that if you view disk 0 to disk management shows a system reserved about 100 MB, and C the boot partition, and you already have 4 partitions on basic and if you add another partition, it must be configured as dynamic.

    You cannot convert dynamic to basic use in victory built tools.

    When you create the recovery discs, and I hope that you have done this now, if you ever have to recover your system, you will lose all you have created the partitions and all data.

    Bottom line, your goal/plan to create a separate partition is incorrect. Go back and expand C to consume all the free space.
