VMWare Datastore Recovery

I have a VMWare host.  It was an older server and it had 1TB of local storage as DataStore_01.  When it came time to upgrade the server I removed the local hard drives and installed them in the new server in the exact same order as the older server.

My intention was to reformat these drives because the only data on the local store was a couple of old decommissioned vm's that we were not going to ever need again.

So, 6 months later and before I had the opportunity to format the drive, I am told that there was a development project on one of the old servers that they had decided to work on again.

So now I have the new host with unconfigured local storage that I need to retrieve a VM from.  Is there any way to accomplisht this.

I have tired using the web client to add the datastore on the new server, but get an error that says "A VMFS volume with the same UUID '500e9b3e-0acc2cce-4c8e-001b78bca1d4' is already mounted in the datacenter."

So if I look at storage, I do see that datastore, but it says inactive.  Is there a way to dismount the old datastore and then mount it on the new server?

All options to delete, mount, unmount etc... are unavailable.  See screenshot.

So you removed these disks from a server, and added them back to a different server ?

no changes have occured to the logical disk or array configuration ?

Andrew that is correct.  All drives removed from old server and placed into new server in the same order.  No changes have occurred to the logical disk or array configuration.

Can you check if the old datastore, has any references to it, e.g. VMs, disks, ISOS, floppy images ?

How could I accomplish that.  Where should I look.  

I have attached a screen shot of the datastore summary.

It has a single VM and no hosts.  This VM is the one I need to retrieve files off of.

if you look at the Datastore Inventory.

Probably easier less complicated view in the old vSphere Client (thick!)

It does have a VM in inventory, but it is the vm that I can't lose.  How do I remove it from the inactive Datastore without losing it.

I know that the data is really on the hard drive, not on the VCenter DS.  But how do I remove it from the old Datastore?
