Source facts

\n

Cluster Shared Volumes allow multiple cluster nodes to access the same NTFS or ReFS volume concurrently. Microsoft requires a disk to enter the cluster’s Available Storage group before adding it as a CSV. Available Storage holds recognized disks not yet assigned to a specific cluster role. The documented PowerShell verification uses Get-ClusterSharedVolume to list the resulting CSV resources. Microsoft documentation.

\n

Applicability

\n

Use this review for an existing disk that should be added to CSV storage. Identify the cluster, disk resource, current assignment, and intended workload. Keep creation of a new storage volume as a separate operation.

\n

DSE recommendation

\n

Have a second administrator verify the exact disk resource and its present use before adding it. Record the approved target and avoid selecting every available disk merely because the tool offers that operation. Coordinate the change with the storage and workload owners. Preserve the starting inventory and the intended resource name in the change record.

\n

Verification

\n

After the authorized addition, inspect the CSV inventory and confirm that only the intended disk was added. Verify its resulting access path and perform the agreed workload-access test. Compare the final resource assignment with the initial record. Investigate an unexpected disk, name, or path before assigning production data or repeating the operation.
