Hi

what is the Sub-Cluster Master UUID and Sub-Cluster Backup UUID

Hello vSohill,

These are the CMMDS UUIDs of the current nodes elected as Master and Backup roles for the cluster.

Thanks Bob, What is the role for the backup role in vSAN cluster?

Hello vSohill​

If the node currently elected as cluster Master becomes unavailable, the node currently elected as Backup becomes Master (and a new node is elected as Backup).
