Managing Duplicate VMFS Datastores with vicfg-volume Each VMFS datastore created in a LUN has a unique UUID that is stored in the file system superblock. ESXi can detect the VMFS datastore copy and display it in the vSphere Web Client. The best practice is to maintain a register of the cluster IDs used across the data center to avoid use of duplicate IDs. It’s the world’s fastest, most complete and easiest-to-use backup solution on the market today. bios is not a duplicate.

The new UUID would be unknown to the vShield Manager/NSX, Deep Security Virtual Appliance, or DSM, but would be recognized as protected via vCenter connection. ESX can determine whether a LUN contains the VMFS datastore copy, and either mount the datastore copy with its original UUID or change the UUID, thus When you use vSphere Storage vMotion on vSphere Virtual Volumes storage, the UUID of a virtual disk might change. I also had this issue however it was not with an empty sysinfo_uuid value, it was trying to insert '4c4c4544-004e-4610-8033-c8c04f465131' as the value of sysinfo_uuid. Alternatively, you may create a new UUID (this is known as a resignature) for the datastore and this way both disks may be brought online at the same time.
