Diagnosing NS_E_REMIRRORED_DISK

NS_E_REMIRRORED_DISK identifies this Windows Media Services boundary: A disk has been remirrored; record the disk identity and current mirror generation.

Why this boundary matters

This HRESULT identifies a Content Server storage transition or I/O boundary. Correlate disk UID, membership/layout generation, requested state and the first lower-level storage result before replacing media or rebuilding unrelated members.

Evidence to collect

FieldWhat to preserve
MemberDisk UID and Content Server identity for the member being changed or accessed.
LayoutCurrent layout/generation and membership visible to the same administrative object.
LifecycleOnline, rebuild, restripe or mirror state immediately before the failed transition.
Storage resultFirst lower-level I/O or management result tied to that same disk generation.

Decision rule

Do not replace or rebuild unrelated members until the failing disk UID and current layout generation identify the exact storage transition that failed.

Focused test

Record the disk UID and mirror generation seen by the failing operation; refresh the server object and verify it uses the current remirrored member.

Verification

Repeat the requested operation against the same disk UID and current layout generation. Confirm the intended state transition or I/O completes and that the lower-level storage result does not reappear.
