Mounting a LeftHand VSA snapshot at DR location. Cannot change Host Configuration

Hey Experts,
I have a fairly large setup but i will try to explain it as simple as i can.

"Main Location"
2 HP VMware 5.0 servers.  Setup with HA.
HP P4000 LeftHand SAN.  (Mirrored SANs with 3TB storage)

"DR Location"
1 HP Vmware 5.0 server.
VSA "HP Virtual Lefthand software"...

The main location Lefthand is doing a remote snapshot a few times a week.
We recently tried at the remote location....Assigning the snapshot to the ESXI 5.0 server.  Going into the storage and trying to mount the datastore from the snapshot.  When we try this we get a message saying Call "HostStorageSystem.ResolveMultipleUnresolvedVmfsVolumes" for object "storageSystem-2100" on vCenter Server "vCenter" failed.

We cannot seem to figure out what this error means.  I have this same setup in a lab environment and have been able to mount snapshots as if it was at the DR location just fine.

Any help with be greatly appreciated on this.
Thank you!

Are you managing your DR and source ESX hosts via the same vCenter?  This is the most likely cause of the issue in most cases

Yes i am have the Main and DR location being managed from the same Vcenter/Datacenter.

Should i try making a new Datacenter withing Vcenter and move that ESXI to there?

This may work, this describes Option C in the KB

By relocating the ESX hosts within the vCenter.

Alternatively, you can move each ESX host to its own datacenter before starting the Add Storage operation.

Warning: This option may be disruptive in a production environment, especially if there are more than two hosts in the same datacenter.

That is exactly what the issue was.  Once i made a new DataCenter in Vcenter.  Moved that ESXI host over to there i was able to mount it just fine.
