Source facts

\n

Microsoft permits enabling BitLocker on a clustered volume either before or after the volume joins the cluster. Its instructions call for putting the resource in maintenance mode first. Microsoft prefers PowerShell or Manage-BDE for CSV administration because volumes without drive letters are absent from the BitLocker Control Panel interface. Microsoft’s CSV guidance also requires installing the BitLocker feature on every cluster node.

\n

Applicability

\n

Identify the operating-system release, volume type, cluster membership, and current protector before adapting the procedure. Review the source’s protector discussion for that configuration. Do not infer that one node’s successful unlock establishes the recovery behavior of the entire cluster.

\n

DSE recommendation

\n

Prepare a volume-by-volume maintenance record. Include the node owners, protected workload, authorized recovery personnel, approved recovery-key location, and the intended management tool. Have the workload owner approve the interruption and document the command scope before execution. Keep recovery material out of ordinary tickets and article comments.

\n

Verification

\n

In an approved test, record encryption and protector state, the maintenance transition, and unlock behavior from each intended node. Include a planned workload move and a recovery exercise appropriate to the configuration. Record failures separately from successful tests, and leave unresolved recovery questions open before expanding deployment.
