Hi all,

Here is my issue: we've a VMware VM with Win 2012r2 running on it with 4 disks connected as RDM in physical compatibility mode. The LUNs belong to a DELL compellent SCv2020. I have deleted a lot of data from this 4 disks a freed up several terabytes in each drive, but I don't see it reflecting in the storage.

Is there any command I should run on windows to mark blocks as free so the storage can recognize them? I mean, something similar to ESXi command "vmfs unmap ".

Thanks
