### Logical drive [number] is blocked on controller [number].

Explanation: When the ServeRAID controller performs a rebuild operation on an array, it reconstructs the data that was stored in RAID level-1 and RAID level-5 logical drives. However, the ServeRAID controller cannot reconstruct the data that was stored in any RAID level-0 logical drives in that array. The data in the RAID level-0 logical drives is blocked when the ServeRAID controller detects that the array is valid, but the data might be damaged.

Action: Unblock the logical drive once the rebuild is complete.
