Error: VDS disk object not found.

Hi Everyone,

I have an issue where when creating LUNs from Windows hosts in SQL Cluster using Snapdrive we get the following error in Snapdrive console.

"Disk Create operation on server - xxxxxxxxxx failed for reason - VDS disk object for the LUN s/n 'W-XKBZbvf7eK' has not been found"

I have a workaround for this but i would not expect this to be the acceptable behaviour of Snapdrive. Can anyone advise me on how i can fix this. I want to hand over the creation of LUNs to the Windows Server team as they do not ordinarilly allow non Windows Sys-Admins to have administrator accounts on their servers (they have given my account local admin access on servers). However, until i can get this issue sorted I cannot honestly pass this onto to the Windows admins to do. Thanks in advance.

Details of our environment:

~ Windows Server 2008 R2

~ MS SQL 2008 cluster (x3 nodes)

~ SnapManager for SQL 5.0

~ Snapdrive 6.3

~ ONtapDSM 3.4.5 (MPIO)

~ Data ONtap 7.3.5 run on filers

~ FC protocol

I have attached the screenshot of error but the text format is below.

Re: Error: VDS disk object not found.

I have this issue too.

What was your workaround?

Re: Error: VDS disk object not found.

check if

http://support.microsoft.com/kb/931300

is installed

Check MPIO config and If there are Virus scanners interfering.

this is in general a Microsoft issue
