In Use Space Exceeds the Warning Limit
Several of my volumes on my PS 6100E & X EqualLogic Arrays are reporting the In Use Space Exceeds the Warning Limit. VMWare shows plenty of disk space available on these volumes. I'm aware of some KBs of reclaiming disk space on thin-provisioned arrays but they aren't very intuitive and I'm hesitant to attack the problem without some insight from someone who might have already been through this.
Thanks in advance,
Dave

Thanks Don. We are using ESXi 5.1 and the EQL firmware is 7.0.1. The file system is VMFS 5.54 and we did not upgrade from V3. We are not replicating the Volumes, just individual VMs through VReplication. There are no EQL snapshots.
I'm aware the in-use space has reached the set warning threshold notification but what concerns me is that EqualLogic Group Manager is showing 4.82TB, for instance, in use with 179GB free. VMWare thinks the volume has only 1.68TB provisioned with 3.33TB free which is probably the case given I've done a fair amount of VMotioning and VM deletions.
I just would like to reclaim some of that disk space that really isn't being used. A VMWare KB at kb.vmware.com/.../search.do;cmd=displayKC&externalId=2014849 really isn't very helpful so I thought going to the Dell source might help more.
Thanks,
Dave

Thanks Don. I'm just a little apprehensive running commands on a datastore that houses production data. I do, however, have a test volume that might be worthy of guinea pig status.

I will run the procedure tonight or early in the morning on the Test volume and let you know how it went.

Ran the routine on my Test and Training Volumes. Works great! Thanks Don.

Yep, I ran it several times on each of my volumes and reclaimed almost exactly, not quite like you said, the disk space available reported by ESXi. I was wondering, however, if UNMAP then kills the file it creates when reclaiming free blocks after completion or just what happens with that file.
