Recovering from a Hard Disk Drive Failure

Recovering from a Hard Disk Drive Failure

•  Recovering from a Failed ServeRAID II Adapter
•  Recovering from a Failed Server
•  Troubleshooting ServeRAID II Subsystems in a Cluster Environment

1.  Remove the failed hard disk drive from your server.

    For information on how to remove the hard disk drive from your server, see the documentation that is  included with your server and the 'IBM ServeRAID II Installation and User's Guide.

2.  Install a new hard disk drive.

    For information on how to install the new hard disk drive, see the documentation that is included with  your server and the 'IBM ServeRAID II Installation and User's Guide'.

3.  Restore logical drives.

    If the failed hard disk drive is part of a critical RAID level-1 or RAID level-5 logical drive, you must  perform a rebuild operation to restore the logical drive to the OKY state.
    If the failed hard disk drive is part of a RAID level-0, -1, or -5 logical drive in the OFFLINE state, the data may have been lost.
    You must set each DDD (defunct) drive to the ONL state, except the last DDD drive in RAID level 1 and  level 5 must be set to the RBL state. Then, restore the logical drive from a backup copy.
