Virtual disk MD3000i not on the path preferred because of the AVT/RDAC failover

Hello

I am having some problems with my MD3000i failover to a non-prefere path.

The MD3000i up the old mistake "Not on virtual disk preferred path due the AVT/RDAC failover" several times a day.

It happened from time to time with ESX 3.5, but not much more happenging with version 4.

In the var, I get the following:

I spoke with people from Dell and Vmware support.

Support for VMWare counterpart said that it is a matter of Dell... that VMware is a path problem and do what it is supposed to do.

The Dell guy says there is nothing wrong with the MD3000i and the problem is with VMWare.

None of them seem interested in helping me out more.

I tried using MRU (default) & political pathing Round-Robin and set up iscsi on the host esx, in accordance with the following document:

http://www.delltechcenter.com/page/VMware ESX4.0andPowerVault MD3000i

I can vmkping for all the guests of all the peoples on the MD3000i without any problem.

If someone saw, I would be very grateful.

Thank you

Jason

Hmmm...  Well, if they are flipping back has nothing to do with VMWare, it is certainly a matter of Dell.  Have you tried their repatriation to the correct drives and then just reboot the stupid thing?

  • Virtual disk MD3000i not on the preferred path

    Our MD3000i rpet table is not optimal and that a virtual disk is not on the preferred path.

    Using MD storage manager, I can change VD2 owned by controller 1.   But in the current for the next several hours, it passes backward, and the MD3000i starts orange flashing again.

    If I restart the server that is attached to it, the question usually begins without having to wait a few hours.

    I changed out Ethernet cables, and it did not help.  Either way, it all started when we changed the MD3000i attached to hosts.  It was attached to two Dell servers, now it is only attached to one.

    After looking through everything, it seems that the iSCSI initiator is configured incorrectly. It seems that you only have one configuration of IP and the MD has two available. Here is a link that has a step by step on setting up the MD3000i and the MPIO.

    I am running vmware player 5.0.1 for windows 7 x 64.

    The "EVANS - WHS 2011-0.vmdk" file is a virtual hard disk of metadata, which is a pointer to a physical hard disk and you are not supposed to suspend, snapshot, a Virtual Machine that uses a raw disk such as this and the physical drive could trash making!

  • Extended virtual disk - Windows 7 has the right size - a former size VMWare

    I extended a 100-150 GB virtual drive using the slider under VMWare disk/SCSI settings.  I then started Windows 7 and the size of the disk is correct, 150 GB with 49 GB free.

    Under VMWare Fusion settings, 'Get info', it still shows it as 100 GB with free to talk about anything.

    Tried to remove and replace the drive, but he returned as 100 GB.

    Also tried, as suggested in the forum the following.

    DiskPart > list volume

    DiskPart > select volume 3 (select the number according to your requirement)

    DiskPart > extend filesystem

    I see now what they say, it must not contain the volume of pages, but Windows 7 is fine after that, so I don't know that's the problem.

    Hi Fishing2Day,

    Thank you for using the merger.

    If you do not check "Pre-allocate disk space", the size of the disk will not occupy the ability at the same time, so as you describe it "under VMWare Fusion settings, 'Get info', it still shows it as 100 GB with free to talk about anything."

    But if you check "pre-allocate disk space", Fusion will be the ability at the same time, no matter when you write the data.

    Hope this is a help to you.

  • Resumption of the Suspended virtual machine does not work, "the specified file is not a virtual disk.

    Resume a Suspended computer virtual fails with the message "the specified file is not a virtual disk. Tried to go back to the last snapshot fails with the same message "error restoring snapshot: the specified file is not a virtual disk '. '"

    The virtual machine has worked without delivers up to 21/12/2015 while she was snecessary. I often suspend > resume this machine virtual, but for some reason, I am now getting this error. Please help!

    The file unfortunately doesn't look very promising. It seems that the contents were crushed,

    Unless you have a backup, you can try to replace this file with a file 'empty' hard (e.g. copy Windows 7 x 64-000002-s100. ) ( vmdk) that contains only metadata (size = 327 680), to see if this allows you to use the virtual machine again. Note that you will lose all the data stored in the (corrupt) original hard file, and that the virtual machine will probably suffer file system errors. So make sure that you run chkdsk for all partitions in the guest OS.

    In any case, before doing so, I strongly recommend that you back up the existing files of the virtual machine! Once done, it could also be a good idea to run chkdsk for physical training.

    BTW. do you need all the snapshots? With all these clichés and the size of the virtual disk of the virtual machine, the virtual disk consists of files hard ~ 400.

  • Expanded the bad virtual disk but not Guest OS - Shrink?

    Not quite another question generic "shrink the VMDK.

    I accidentally spread the bad virtual disk in vCenter 725 GB to 1 TB. Fortunately, I realized that until I expanded the partition to use the new space in Windows. Is it possible to reclaim that space? In the virtual machine settings, I have the options of arrow to "reduce" the size down, but I'm not sure on the impact at the prompt to do. Certainly if the guest has not been extended to consume this space then it should be recoverable?

    as you're talking about: the option arrow in the virtual machine settings

    This does not leave you reduce (Shrink) the size of the virtual disk, which has already been strengthened. This option is useful in the case when we say you went into settings of the virtual machine, the disk size increased from 10 to 20 GB, but not yet committed that change and you want to return to 15 you can then use this arrow to do.

  • Virtual MACHINE disk, but not in the inventory

    I have a virtual machine that has disappeared from the inventory, but is still in the (non-local) data store. In my view, that it was off. I tried to add to the inventory, but received a message that a virtual machine is already registered with that name. I believe that these are the steps that led to this State:

    I had a consultant in an ESXi host to replace it with a new one and a few weeks ago. All virtual machines have been moved out of the old host. The virtual machine in question was arrested that we did not use it. I just noticed today that it was not in the inventory because now I'm ready to use it.

    Another change that happened a few weeks ago was replacement unit vCenter vCenter. I don't know if who had nothing to do with him or not.

    Any suggestions how I could see the virtual machine in the inventory again?

    Hello

    As you can see this message, "received a message that a virtual machine is already registered with that name", while adding another virtual machine name use inventory. However, be sure that this virtual machine is not already.

  • The initialization of the swap file to virtual disk periodically (40% of the time +/-) fails to start Windows

    Greetings-

    For the past year or so I put my Windows 7 32-bit, 8 GB RAM system to initialize the page automatically on a virtual disk file (in order to reduce the physical disk reads/writes and to speed up the access to the page files).

    Here's how I set up: I installed Dataram Ramdisk and configured to use memory beyond 4 GB (which, as everyone here knows, 32-bit Windows can not otherwise use) as the ramdisk.  In setting up manually formatted the 4 GB unallocated space virtual drive as an NTFS volume and it gave the letter a: (what else!). Then I got the software save an image file of the ramdisk formatted my hard drive F:. Additional configuration of the software wants to initialize the virtual disk to start and immediately copy the image file to the virtual disk, thus creating a 4 GB NTFS formatted volume a:. (Incidentally, I also use the virtual disk to the cache of the browser and the print spooler). The theory here is flawless. But to make it work in practice, the virtual disk must be initialized and the image file copied into ramdisk (making it a formatted disk R :) front Windows initializes the pagefile.

    It runs about 60% of the time, but for the remaining 40 percent Windows gives an error message indicating that Windows has created the page file in a temporary location (it's always the C: drive, the pagefile in general where default.). The only reasonable explanation I see why it fails is that, for nearly 40% of my computer boots window wants to initialize the page file before the ramdisk is ready to receive. What I don't understand is why that happens.

    This happen to my main question: is it possible to control the Windows boot sequence so that the ramdisk is initialized and the filename of the image copied to him on a basis consistent before Windows wants to initialize the page file? Operationally, I guess it boils down to whether it is possible, during each startup sequence, to delay initialization of the page files or to move the virtual boot record earlier in the sequence. If so, how to do that? If not, can someone explain why the order of the respective boots usually works, but does not reach a good amount as well?

    Ideas on this would be appreciated.

    RAS43

    Create a small paging file to 20 MB on the boot volume (the partition where the Windows files are installed) this way the session manager will be able to start the Windows session and create additional paging files without complaining.  You can have more than one paging on several disks, Windows will favour the less busy the disk paging file.

  • Virtual disk is not expanding

    I have increased my virtual disk of 60 GB to 100 GB and I read that when doing so in my Windows 7 virtual disk would automatically increase. However, this was not the case. If I go to computer management and watch my drive under storage, I see that the drive is in larger size, but I can't develop so that it uses all the space. The alternative to "Develop" menu drop-down is disabled. Any input on what to do? I do not know if it is a problem related to merging or Windows...

    Not all disks in Windows are extensible, it's for sure a Windows problem.

    You might have better luck using a few tools like gparted.

  • Additional virtual disk space not usable in Windows

    I resized a virtual disk of virtual machines by changing properties and then used a live CD partitioning tool to resize the partition.  Inside windows disk manager, it shows that the additional disk space as if the size of the Windows partition has been increased with success.  However, when I look at the properties of the hard drive in Windows, the extra size does NOT appear and it is not usable or accessible to the file system.  Any ideas what went wrong and how to fix it?

    Thank you

    I had exactly this before strange point of view and could not explain it. Seemed rather strange that the operating system will appear to display the disk space as allocted but the extra space was not available (even when checking the query WMI etc.)

    Ultimately, however, EXTPart has remedied the problem for me. (and quickly)

    If you do not use EXTPart, you can use the converter to recreate the disk.
