Run cluster validation before creating a Hyper-V cluster on PowerStore. All tests related to storage and MPIO should pass before configuring a Hyper-V cluster and deploying a workload.
- Stage each Windows Server and configure the Hyper-V role according to Microsoft best practices.
- Configure two or more data paths to PowerStore for each host (iSCSI or FC).
- Install and configure MPIO on each host.
- Use PowerStore Manager to create a host group on PowerStore.
- Use PowerStore Manager to map at least one cluster volume to the host group using a consistent LUN ID.
- On a host, initialize the new disk, bring it online, and format it.
- Perform a disk rescan on each host in the host group.
- Use Failover Cluster Manager to run cluster validation for the hosts in the host group.
- Verify that all tests related to disk and MPIO pass.
- If any tests fail, the configuration might not support clustering. Troubleshoot and resolve all disk or MPIO failures and run cluster validation again until they pass.

Minor warnings will not prevent hosts from being clustered. For example, cluster validation might detect slight differences in the patch level of fully updated hosts and generate a warning. Even if updates are current on all tested hosts, this test might detect minor differences.

You can also use Windows Admin Center, in addition to Failover Cluster Manager, to create and manage clusters.
