Betreff: MSA1050 - Perform manual VMFS unmap on vSphere 6.5 with VMFS 6

[Caeru]

Hello, I have a question.
I use MSA1050 storage but Automatic space reclamation doesn't work on VMFS6.
Can I Perform manual VMFS unmap on vSphere 6.5 with VMFS 6 with next command:

 esxcli storage vmfs unmap -l MyDatastore

Thanks in Advance

Yes, that's the correct command.

The CLI Cursor will disappear until it is done, which can be 10-45min, depending on the Volume Size.

Do not cancel!

There is also no progress Information.

It is complete if the Cursor comes back and gives you no feedback.

I do this regularly on many VMFS 6 Volumes.

Тhanks,

I ran the command, it took about 15 minutes for an 8TB Volume Size.
