SIP3112

This procedure resolves the problem when one or more disk array members are not at the required physical locations.

The possible SRC is SRC xxxx9023.

  1. Identify the affected adapter and disk units that are not at their required locations by examining the Product Activity Log. Perform the following:
    1. Access SST or DST.
      • If you can enter a command at the console, access system service tools (SST). See System Service Tools (SST).
      • If you cannot enter a command at the console, perform an IPL to DST. See Performing an IPL to DST.
      • If you cannot perform a type A or B IPL, perform a type D IPL from removable media.
    2. Access the Product Activity Log and record address information.
      If a D IPL was NOT performed to get to SST or DST:
      The log information is formatted. Access the Product Activity Log and display the SRC that sent you here. Press the F9 key for "Address Information". This is the adapter address. Then, press F12 to cancel and return to the previous screen. Then press the F4 key to view the "Additional Information" to record the formatted log information. Record all devices that are not at their required locations. These are the array members that have a current address and an expected address which do not match. A current address of 0 is acceptable, and no action is needed to correct it for a known failed drive in the array.
      If a D IPL was performed to get to DST:
      The log information is not formatted. Access the Product Activity Log and display the SRC that sent you here. The direct select address (DSA) of the adapter is in the format BBBB-Cc-bb:
      BBBB
      hexadecimal offsets 4C and 4D
      Cc
      hexadecimal offset 51
      bb
      hexadecimal offset 4F

      In order to interpret the hexadecimal information to get device addresses, see More information from hexadecimal reports. Record all devices that are not at their required locations. These are the array members that have a current address and an expected address which do not match. A current address of 0 is acceptable, and no action is needed to correct it for a known failed drive in the array.

    3. Determine the location of the adapter and the devices that are causing the problem. See Locating FRUs and find the diagram of the system unit, or the expansion unit. Then find the following:
      • The card slot that is identified by the adapter direct select address (DSA).
      • The disk unit locations that are identified by the unit addresses.
  2. Perform only one of the following options (listed in order of preference):
    Option 1
    Power off the system or partition and install the identified disk units in the correct physical locations (that is the expected addresses) in the system. This ends the procedure.
    Option 2
    Stop the disk array that contains the missing devices.
    Attention: Customer data might be lost.

    Perform the following:

    1. If you are not already using dedicated service tools, perform an IPL to DST. See Performing an IPL to DST. If you cannot perform a type A or B IPL, perform a type D IPL from removable media.
    2. Select Work with disk units. Did you get to DST with a Type D IPL?
      No:
      Select Work with disk configuration -> Work with device parity protection. Then, continue with substep 2c.
      Yes:
      Continue with the next substep 2c.
    3. Select Stop device parity protection.
    4. Follow the on-line instructions to stop device parity protection.
    5. Perform an IPL from disk.

    Does the IPL complete successfully?

    No:
    Go to Starting a Service Call. This ends the procedure.
    Yes:
    This ends the procedure.
    Option 3
    If the data on the disk units is not needed, initialize and format the remaining members of the disk array by performing the following steps:
    Attention: Data on the disk unit will be lost.

    If a D IPL was NOT performed to get to SST or DST:

    1. Access SST or DST.
    2. Select Work with disk units -> Work with disk unit recovery -> Disk unit problem recovery procedures.
    3. Select Initialize and format disk unit for each disk unit. When the new disk unit is initialized and formatted, the display shows that the status is complete. This might take 30 minutes or much longer depending on the capacity of the disk unit. The disk unit is now ready to be added to the system configuration. This ends the procedure.

    If a D IPL was performed to get to DST:

    1. Access DST.
    2. Select Work with disk units.
    3. Select Initialize and format disk unit for each disk unit. When the new disk unit is initialized and formatted, the display shows that the status is complete. This might take 30 minutes or much longer depending on the capacity of the disk unit. The disk unit is now ready to be added to the system configuration. This ends the procedure.
