Unblocking Logical Drives

Unblocking Logical Drives

Unblocking Logical Drives: Whenever the ServeRAID controller performs a rebuild operation on an array, the data stored in any RAID level 1 and RAID level 5 logical drives in the array is reconstructed. However, the data stored in RAID level 0 logical drives in that array cannot be reconstructed. 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.

After the rebuild process completes, you can unblock the RAID level 0 logical drives, this redefines their state as OKY and allows access to them once again. But remember, the RAID level 0 logical drive might contain damaged data. You must re-create, install, or restore the data for the RAID level 0 logical drive from the most recent backup disk or tape.

To unblock a blocked drive:

1.  Select the logical drive that is blocked from the Main Menu of the Administration and Monitoring utility program.

    A screen similar to the following appears.
   

    
   
2.  Click on Unblock to unblock the drive.
3.  You initialize all new logical drives before storing data in them. See Initializing Logical Drives
4.  Restore the data to the drive from the most recent backup disk or tape.
