vaai - Delete status "unsupported"

[piseema]

Hi Friends,

I have an interesting issue where one of the VAAI primitive stays "unsupported"

configuration:

VMware ESXi, 5.1.0, 799733

Storage: Hitachi VSP

               FC

               Two luns, 1) 10GB and 2) 1TB

               Both are in same Host-Groups so same Host-mode options are applied to them.

Here is what I see

Only difference is the size - one lun is 10gb which is showing as everything supported while other one is 1TB and Delete Status says "unsupported"

Your input is greatly appreciated.

Thank you,

PK.

This is unusual. can you confirm if there is a difference in RAID configuration

Thanks for Replying Akash.

I did figured this out. The 10G lun mentioned in my post was actually a Basic lun and not a Thin Provisioned LUN, obviously UNMAP will say "unsupported".
