SnapDrive 6.2 disk arrival timeout on ESX 4.0 W2k3 guest

moncsko — Thu, 05 Jun 2025 07:20:43 GMT

Hi All,

I’ve run into an issue where when I try to create and mount a LUN in a w2k3 VM running on an ESX 4 cluster I get a disk arrival timeout error. The LUN gets created and mapped to an initiator group, but then fails to mount on the guest. The ESX server sees it when I do a storage rescan but the guest OS won’t mount it.

Anyone seen this behavior before?

Thanks.

Please set the following timeout value in windows registry of the VM:

My Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Disk\TimeOutValue (DWORD) = 190

Thanks for the reply. I had already made this registry change, so that wasn't the problem.

Hi,

Why did you install "mpio 3.3.1". this is not needed when installing snapdrive 6.2 in a vmware guest OS.

Are you using FCP of iSCSI ?

Did you replaced the LSI scsi drivers with the storport driver ? See http://now.netapp.com/NOW/download/software/snapdrive_win/6.2/ for more information.

Also try using the latest version of snapdrive (6.2P1). You can find it here http://now.netapp.com/NOW/download/software/snapdrive_win/6.2P1/

The ESX box is FC attached

The LSI driver has been upgraded. It now reads LSI Adapter, Ultra320 SCSI 2000 series, (w/1020/1030)(StorPort)

Okay I uninstalled all the Netapp software and rebooted the vm server

Re-installed Host Utilities - it asks a question if I am running multiple paths to the filer heads? Do I answer Yes or No ?

I have the ESX box with two fiber channel ports to the SAN. Both initiators are shown in the igroup.

Hi,

Just install snapdrive.

Don't install Host utilis or MPIO in you vmware guest os. Those functionality is handled by your vmware host (You should install host utilities on your vmware ESX, vmware is mpio ready)

Read through http://media.netapp.com/documents/tr-3428.pdf for the full explenation how to install your vmware & netapp enviroment

Read through http://now.netapp.com/NOW/knowledge/docs/snapdrive/relsnap62/pdfs/admin.pdf and search for vmware.

Confirmed. I installed just SnapDrive on the client VM and was able to create a disk. Thanks for letting me know that HUK and MPIO are not required on a VM guess OS.
