What does HRESULT 0x8004257C (VDS_E_VOLUME_NOT_FOUND_IN_PACK) mean?

VDS_E_VOLUME_NOT_FOUND_IN_PACK

Volumes are created within a pack and IVdsVolume::GetPack exposes the containing pack relationship. Pack-scoped topology operations must use volumes from that disk group. A volume GUID can identify a real VDS object and still be invalid for a method invoked on another pack. This HRESULT marks that ownership mismatch.

Why this state matters

Stale selections are a common source of the problem after disk migration, mirror changes, or reenumeration. Do not match a volume to a pack by drive letter: access paths can change and are not pack identity. Enumerate the pack volumes or resolve the volume's containing pack, then compare VDS object IDs immediately before constructing the request.
