One DHS Drive, One or More DDD Drives, and One RBL Drive

•  One DHS Drive, No RBL
•  One DDD Drive, One DHS Drive, No RBL
•  More Than One DDD Drive, One DHS, No RBL

Important: The ServeRAID adapter must be using firmware level 2.87 or later for the following procedure to have a chance at success.

Usually when you have a RBL drive after bringing up a system, it is because the data on the drive was being rebuilt when the system went down. If there are DDD drives as well, those drives are more than likely the cause of the system crash.
The following steps allow you to attempt to recover the logical drive:

1.  Boot to the ServeRAID DOS Configuration Diskette for the ServeRAID adapter.
2.  Choose View Configuration.
3.  Write down the current status of each drive.
4.  Physically replace the DHS drive.
5.  Return to the utility's Main Menu and choose Device Management.
6.  Choose Set Device State.

    If you see any DDD drives, highlight them and change their status to ONL.

    If you do not see any DDD drives, highlight the DHS drive and change its state  to HSP, or SHS, as appropriate. Repeat this step until there are no more drives marked DDD or DHS.

7.  Choose Rebuild and highlight the RBL drive.
    The rebuild process begins, and all data will be rebuilt to the drive.
