When HSP is Present at Time of Failure

When HSP is Present at Time of Failure

Use the following recovery procedures when an HSP state is present at the time of a disk failure:

One DHS Drive, No RBL

•  One DDD Drive, One DHS Drive, No RBL
•  More Than One DDD Drive, One DHS, No RBL
•  One DHS Drive, One or More DDD Drives, and One RBL Drive

•  Only one drive is marked DHS and the rest are ONL.
•  The ServeRAID logical drive status is OKY because an HSP is present in the system.
   Either the HSP drive is the hard drive that went DHS or the HSP drive has already taken over for the DHS drive  automatically and has been rebuilt successfully.

•  There are no drives with a RBL status.

Once you verify the conditions above through either the ServeRAID Administration log or the ServeRAID Administration Utility, perform the following steps to bring the DHS drive back to HSP status:

1.  Physically replace the DHS hard drive with a new one of the same capacity or greater in the same location.
    If Hot-Swap Rebuild is Enabled, the state of the new drive will automatically be set to HSP.
    If this occurs, skip to step 5. If the new drive is not automatically set to HSP, then this must be done manually.
    Instructions for manually setting the drive state continue with step 2.

2.  With a RAID-1 or RAID-5 logical drive, the operating system is still functional at this point.
    Use either Netfinity Manager 5.0 (or later) or the ServeRAID Administration Utility to bring the drive back  to HSP status. Using the ServeRAID Administration Utility, select the DHS drive.

3.  A window named Device Management appears, listing all the possible drive states.
    Select Hot-Spare (HSP), or Standby Hot-Spare (SHS) if necessary, then select Set Device State.

4.  The adapter issues a start unit command to the drive.
    Once the drive successfully spins up, the adapter changes the drive's state to HSP (or SHS) and saves the new configuration.
    A message appears that reads, 'Device state changed from DHS to HSP (or SHS)'. Select OK on this  message and then on the Device Management window.

5.  If you see a message that says:

   Error in starting drive

    Reinsert the cables and hard drive to verify that they are connected properly, then go to step 2.
    If the error persists, go to step 1.

6.  If the error still occurs with a hard drive that is known to be good, troubleshoot to determine the defective part.
    The defective part can be a cable, a back plane, a ServeRAID adapter, or some other component.
    Once you have replaced the defective part so that there is a good connection  between the adapter and the hard drive, go to step 2.
