Use a consistent LUN number when you map a shared volume to a Hyper-V cluster: quorum disks, cluster disks, and cluster shared volumes. Configure host groups in PowerStore Manager as a best practice. When you map a shared volume to a host group in PowerStore Manager, the wizard assigns the next available LUN number that is common on each Hyper-V node automatically.
Note: PowerStore host groups do not support Hyper-V hosts that use boot-from-SAN.
If you do not use PowerStore host groups, use PowerStore Manager to change LUN IDs if necessary. Ensure that LUN IDs are consistent after a shared volume is mapped to multiple Hyper-V nodes.
