One DDD Drive, No RBL



One DDD Drive, No RBL

Follow these steps to bring the DDD drive back to the ONL state if the following items are true:


Once the conditions above are verified through either the RAID administration log or the ServeRAID Administration Utility, perform the following steps to bring the DDD drive back to ONL status.
  1.  If drive has never been marked DDD, proceed  to step 3 to software-replace the drive using the ServeRAID Administration and  Monitoring Utility or Netfinity ServeRAID Manager.

    Note: Refer to Software and Physical Replacement  to understand differences between software and physical replacement.

  2.  If the drive has been marked DDD before,  physically replace the hard drive in the DDD SID with a new one of the same capacity or greater.
  3.  With a RAID-1 or RAID-5 logical drive, the operating system will be functional.
     Use either Netfinity Manager or the ServeRAID Administration Utility within the operating system to start the  Rebuild process. With the ServeRAID Administration Utility, select the drive  marked DDD, and choose Rebuild from the menu that appears.

  4.  The adapter issues a start unit command to the drive.
     The drive then begins the rebuild process.  Once the drive completes this process, the drive's status changes to ONL.
  5.  If you see the message:

      Error in starting drive

     Reinsert the cables, hard drive, etc., to verify there is a good connection.
     Go to step 3. If the error persists, go to step 6.

  6.  Physically replace the hard drive in the DDD SID with a new one of the same capacity  or greater and go to step 3.
  7.  If the error still occurs with a known good hard  file, troubleshoot to determine if the cable, back plane, ServeRAID adapter, or  other component is defective.

    Note: You can view the ServeRAID Device Event Table  by clicking on the logical drive from the ServeRAID Administration and Monitoring Utility.
     If Hard Events are reported in the ServeRAID Device Event Table, refer to Device Event Table  for information. The ServeRAID adapter should not be replaced, in many cases.

  8.  Once you have replaced the defective part so that  there is a good connection between the adapter and the hard drive, go to step 3.
