STATUS_VOLMGR_VOLUME_CONTAINS_MISSING_DISK
The volume topology includes an absent physical disk or LUN
STATUS_VOLMGR_VOLUME_CONTAINS_MISSING_DISK is volume-scoped: at least one disk required by the volume layout is missing. It does not say that the whole pack has failed or that every plex is unavailable.
The impact depends on the volume type. A spanned or striped volume can lose required extents; a mirrored volume may retain another active plex; a RAID-5 volume can enter degraded operation until redundancy is repaired. The same missing-disk fact therefore leads to different data-availability consequences.
Enumerate the volume’s plexes and extents, map the missing disk to its role, and then follow the physical storage path. Microsoft Disk Management guidance recommends checking power, cabling/controller state, and reactivating the disk when the underlying problem is temporary.
What to inspect
- Identify which volume extents or redundant members reside on the missing disk.
- Check whether the disk is Offline, Missing, or Foreign and whether it can be safely reactivated or imported.
- Determine current redundancy before removing the disk object or starting repair of the volume.
