When mapping a PowerStore volume (quorum disk, cluster disk, or CSV) to multiple Hyper-V nodes, map the volume to nodes in the cluster using a consistent LUN number.
Use host groups in PowerStore to simplify the task of mapping a new volume to many nodes simultaneously. This practice can save significant time in larger environments and can help reduce the risk of user error. It also helps ensure that a consistent LUN ID is used for each Hyper-V node a volume is mapped to.
Use the Add Host Group wizard in PowerStore to create a host group. Only hosts that do not have any PowerStore volumes mapped can be added to a new or existing PowerStore host group.
Note: Hosts that are configured to use a PowerStore volume to boot-from-SAN are not eligible for membership in a PowerStore host group.
