I need to reclaimed spaces in HP P4500 storage cluster. The iscsi targets are two vSphere 4 servers.

Here is the picture
It is manifested as a single file on a filesystem, right?

Different volumes containing vmdks of a set of VMs. We need to re-claimed unused spaces in order to create an empty volume for a new VM.
You back up, blow away the .vmdk files, build a new one of the proper size and restore. But the O/S for the VMs using the iSCSI targets and the filesystem used by the iSCSI targets have different methodolories for backup/restore, so ..
1. For whatever O/S your VMs are using, just google 'resize iSCSI target linux' or whatever O/S. It will give commands on what needs to be done to backup/restore. Then back up using that technique, and TEST restoring if there is any doubt.
2. Then blow away the .vmdk files from vSphere mgmt utility.
3. Build right size.
4. Restore using technique in #1.

So, there is no way to claim the unused spaces in HP SAN IQ cluster?
There is a section in this manual on how to shrink volumes on LeftHand systems http://h20195.www2.hp.com/V2/GetPDF.aspx/4AA2-5502ENW.pdf
