UNBLOCK device states" on page 112 for more information.) Use the UNBLOCK command to gain access to a blocked logical drive. RAID level-0 logical drives become blocked if they are in an array that contains RAID level-1 or level-5 logical drives and the array is being rebuilt. Because the RAID level-0 logical drives cannot be rebuilt, the data stored on the RAID level-0 logical drives is damaged and should not be accessed. After you issue the UNBLOCK command, you must re-create or restore the data previously stored on the RAID level-0 logical drives.
