I am using VMware 6.5 with a 600 GB non thin provisioned volume.  I have deleted all virtual machines on this volume.  VMware sees the full 600 GB free space but the san only sees 38 GB free.  I ran the space reclamation command from VMware host but the san still only sees 38 GB free.  How do I get the san to see the full 600 GB free space?
