All VMFS Volumes have a UUID number. Those are then linked to a Datastore name, like : Datastore001. When you do a ‘ls’ from the service console in /vmfs/volumes you should see the names of your datastores linked to the UUID number. But more on the UUID number.

The number is as follow : 123abc98-12abc456-bd12-000569ab56bf

This is what what it means :

• 123abc98 : This is the console time at VMFS creation or when it was resignatured
• 12abc456 : TSC time (This is the CPU time stamp counter)
• bd12 : A Random number
• 000569ab56bf : The Service Console MAC address that created or last updated the UUID

Note that I have just used random hex numbers for the UUID number above.
