Verifying a concurrent repair

Use this procedure to verify a repair that was performed by using concurrent maintenance. Perform this procedure from the partition on which you performed the service action.

1. Was concurrent maintenance just performed on an optical storage unit?
   • No: Continue with the next step.
   • Yes: The Product Activity Log (PAL) and Service Action Log (SAL), in most cases, contain a reference code for the optical storage unit when concurrent maintenance is performed. You may ignore this reference code. Perform the following:
     • Perform the Verification procedures in the Service functions to verify that the problem is corrected.
     • Return the system to the customer and have the customer verify the system date and time. This ends the procedure.
2. Use the SAL to look for any new reference codes (see Using the Service Action Log). Are there any new reference codes?
   • No: Go to step 5.
   • Yes: Continue with the next step.
3. Is the new reference code the same as the original reference code?
   • No: A new symptom may have occurred. Go to Start of call procedure to determine the cause of the problem. This ends the procedure.
   • Yes: Continue with the next step.
4. Are there any other failing items that remain to be exchanged?
   • Yes: Exchange the next failing item listed for reference code. This ends the procedure.
   • No: Contact your next level of support for assistance. This ends the procedure.
5. Are you working with a tape device?
   • No: Continue with the next step.
   • Yes: Perform the Verification procedures in the Service functions to verify that the problem is corrected. After the verification test has completed, the tape device description will be set to the failed state because a resource change was detected. Perform the following:
     • Vary the tape device description off and then on.
     • Return the system to the customer and have the customer verify the system date and time. Then go to Verifying the repair from the HMC. This ends the procedure.
6. Are you working with an IOP or an IOA?
   • No: Perform the Verification procedures in the Service functions to verify that the problem is corrected. Resources that usually vary on automatically during IPL, or that were previously varied on manually, may need to be varied back on after the verification procedures have been completed.

     Return the system to the customer and have the customer verify the system date and time. This ends the procedure.

   • Yes: Use the display hardware configuration service function to check for any missing or failed hardware:
     1. On the command line, enter the Start System Service Tools command (STRSST). If you cannot get to SST, select DST (see Dedicated Service Tools (DST) in the Service functions).
        Attention: Do not IPL the system or partition to get to DST.
     2. On the Start Service Tools Sign On display, type in a user ID with service authority and password.
     3. Select Start a service tool > Hardware service manager > Logical hardware resources > System bus resources.
     4. Select the function key for Include non-reporting resources.
     5. If the IOP or IOA that you just replaced is a failed or non-reporting resource, the problem has not been fixed. Continue to the next failing item in the failing item list. This ends the procedure.
