Hello,
We tested VVol for a few weeks with VMware, and created a few VMs, and decided to completely remove it from the 3PAR. Now, a few months later, I still have a bunch of stale VVs linked to VMs that used to be on the VVol storage container, and I couldn't find a way to remove them.

showcpg:

It shows 38 VVs for CPG FC_r5, although I really only have 1 VV on that CPG!

showvv -cpg FC_r5

Code: Select all

                                                             ----Rsvd(MB)----- -(MB)-

 1 total                                                     1280 82944 243328 409600

Now the "showvvolsc" command shows I have no storage container because I deleted it when removing VVol from the system:

Code: Select all

                       -------(MB)-------

total       0         0      0           0

What do you think?

what about "showvvcpg" and "showvvolvm -sc sys:all" ?

If there are any ghost volumes they should also be in a vvset so showvvset should also display them.

"showvvolvm -sc sys:all" shows all the ghost VMs, but there are no more Storage Container on this system, and the vvol vvset has also been deleted.

All the ghost VMs are in the state "unbound".

There is absolutely no signs of the previous vvol vvset or storage container, only the vvol VMs are there. Also, the CPG in which the vvol vvset used to be still contains the ghost vvol VMs, because it counted towards the number of volumes in the CPG.

What would be the next step?

If there is no storage container and no vvset, there should be no vluns (exports). So you can just delete the VVs. Not sure if you have any options in SSMC but you can do it from CLI.

help removevv
Would be your place to start.

That solved it! Thank you so much for saving my day.

I had to set this environment variable first to see the vvol VMs:

Code: Select all

setclienv matchbulkobjs 1

Then I've been able to do "removevv" for each vvol VM volumes.

Wasn't that simple for me, as my orphaned vvols were part of a storage container vvset:

Code: Select all

cli% removevv -f cfg-VVolTest-a927508d dat-VVolTest-0d195835
Removing vv cfg-VVolTest-a927508d
Removing vv dat-VVolTest-0d195835
Could not remove any VV from the VV list.

Attempt to delete vv cfg-VVolTest-a927508d which is a member of vv set Backend
Attempt to delete vv dat-VVolTest-0d195835 which is a member of vv set Backend

What did the extra job was:

Code: Select all

removevvset vvsetname volume_name
