VDS_E_LUN_FAILED
VDS_E_LUN_FAILED is the array-side counterpart to the disk-state errors. VDS_LUN_PROP reports the LUN status and health maintained by the hardware provider; a failed LUN cannot be used as a safe shrink target even if a stale local disk object still appears online.
Recover the LUN through the provider first
- Query LUN status, health, flags, size and subsystem identity.
- Inspect plex, drive and controller health in the storage array.
- Use the provider recovery workflow and wait for notifications before resizing.
Refreshing Windows disk state cannot repair failed array storage. Conversely, deleting the local disk object does not fix LUN health. Keep provider-side and host-side evidence together, because both layers must agree before a capacity-reducing operation is safe.
