I recently upgraded to VMWare version 5.5 and then migrated my virtual machines from local storage to our new SAN. All migration seemed to work fine except one. I didn't get any errors indicating a problem, but when the migration was finished, I didn't see the VM anymore in the list. So I went to the new location on our SAN and the folder for the VM was there. However, the only file in the folder was the VMDK file and I don't see a way to add it back to inventory. What happened and how do I recover this VM?
