SIP3130

Use this procedure to resolve the following problem: Adapter does not support function expected by one or more disk units (SRC xxxx9008).

1. Identify the affected adapter and disk units by examining the Product Activity Log. Perform the following steps:
   1. Access SST or DST.
      • If you can enter a command at the console, access system service tools (SST). See System service tools.
      • If you cannot enter a command at the console, perform an IPL to DST. See Performing an IPL to dedicated service tools.
      • 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 type 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. The Device Errors Detected field indicates the total number of disk units that are affected. The Device Errors Logged field indicates the number of disk units for which detailed information is provided. Under the Device heading, the unit address, type, serial number, and worldwide ID are provided for up to three disk units. Additionally, the adapter type, serial number, and worldwide ID for each of these disk units indicates the adapter to which the disk was last attached when it was operational.

      If a type 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 . The Device Errors Detected field indicates the total number of disk units that are affected. The Device Errors Logged field indicates the number of disk units for which detailed information is provided. Under the Device heading, the unit address, type, serial number, and worldwide ID are provided for up to three disk units. Additionally, the adapter type, serial number, and worldwide ID for each of these disk units indicates the adapter to which the disk was last attached when it was operational.

   3. Determine the location of the adapter and the devices that are causing the problem. See System FRU locations and find the diagram of the system unit or the expansion unit. Then find the following items:
      • The card slot that is identified by the direct select address (DSA)
      • The disk unit locations that are identified by the unit addresses
      Have you determined the location of the adapter and the devices that are causing the problem?
      • No: Ask your next level of support for assistance. This ends the procedure.
      • Yes: Continue with the next step.
2. Have the adapter or disk units been physically moved recently, or were the disk units previously used by the AIX® or Linux operating system?
   • No: Ask your next level of support for assistance. This ends the procedure.
   • Yes: Continue with the next step.
3. Perform one of the following options (listed in order of preference):

   Option 1

   Power off the system or partition and restore the adapter and disk units back to their original configuration. This ends the procedure.

   Option 2

   If the data on the disk units is not needed, initialize and format the disk units by performing the following steps:

   Attention: Data on the disk unit will be lost.

   If a type 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 type 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.
