I have a vm that somehow ended up with 2 snapshots I have the Server.vmdk and then Server-00001.vmdk and Server-0002.vmdk. The server has run out of space. I moved one of the vm's off and was able to start up the server. The problem is Snapshot Manager shows no snapshots. I know the files are in use for 2 reasons. 1 I cant move them they are in use 
and 2 in the Settings area I see Server-00002.vmdk for the Hard Disk.
I saw vmware-cmd in ESX to re-query for snapshots but not for ESXi. I have both console and RCLI available.
I tried vim-cmd snapshot.remove all pathtomy.vmdk and it basically said no snapshot found. Which I presumed but thought i would give it a try.
Thanks!
