Source facts

\n

Microsoft says a pool warning means the pool remains accessible but has missing or failed drives and may have reduced resilience. An unknown or unhealthy pool is read-only until it returns to an acceptable health state. A virtual-disk warning has a different meaning: some data copies are unavailable, but at least one copy can still be read. Microsoft Learn.

\n

Applicability

\n

Identify whether the reported state belongs to a physical drive, storage pool, virtual disk, or volume. Record health and operational status together. Do not translate the word warning into a single action without identifying the object and its documented meaning.

\n

DSE recommendation

\n

Create an incident record that traces the affected volume to its virtual disk, pool, and underlying drives. Preserve the initial state and any missing-device identifiers before attempting repair. Ask the storage owner to assess remaining resilience and the workload impact. Avoid deleting or recreating an object to clear an unexplained read-only condition. Establish which documented recovery action fits the actual object state.

\n

Verification

\n

Requery the same object identifiers after the approved corrective action and compare health, operational status, and application access with the initial record. Confirm restored resilience separately from basic readability. If the layer-level states disagree or a device remains missing, leave the finding open and escalate with the complete object relationship.
