Verifying a replaced part by using the AIX operating system

If you replaced a part, you might want to use the tools in the AIX® operating system to verify that the part is recognized by the system or logical partition.

To verify the operation of a replacement part, complete the following steps:
  1. Did you use either the AIX operating system or the online diagnostics service aid concurrent (hot-swap) service to replace the part?
    • No: Go to step 2.
    • Yes: Go to step 5.
  2. Is the system powered off?
    • No: Go to step 4.
    • Yes: Continue with the next step.
  3. Start the system and wait until the AIX operating system login prompt is displayed or until apparent system activity on the operator panel or display has stopped.
    Did the AIX login prompt display?
    • No: If a service request number (SRN) or other reference code is displayed, suspect a loose adapter or cable connection. Review the procedures for the part that you replaced to ensure that the new part is installed correctly. If you cannot correct the problem, collect all SRNs or any other reference code information that you see. If the system does not start or you have no login prompt, see: Problems with loading and starting the operating system.

      If the system is partitioned, note the logical partition in which you replaced the part. Contact your service provider for assistance.

    • Yes: Go to step 4.
  4. At the command prompt, type diag —a and press Enter to check for missing resources. If you see a command prompt, go to step 5.
    If the Diagnostic selection menu is shown with M appearing next to any resource, follow these steps:
    1. Select the resource and press Enter.
    2. Select Commit.
    3. Follow any instructions that are shown.
    4. If the Do you want to review the previously displayed error? message is shown, select Yes and press Enter.
    5. If an SRN is shown, suspect a loose card or connection. If no obvious problem is shown, record the SRN and contact your service provider for assistance.
    6. If no SRN is shown, go to step 5.
  5. Test the part by doing the following steps:
    1. At the command line, type diag and press Enter.
    2. From the Function Selection menu, select Advanced Diagnostics Routines and press Enter.
    3. From the Diagnostic Mode Selection menu, select System Verification and press Enter.
    4. Select All Resources, or select the diagnostics for the individual part to test only the part you replaced and any devices that are attached to the part you replaced and press Enter.

      Did the Resource Repair Action menu appear?

    • No: Go to step 6.
    • Yes: Go to step 7.
  6. Did the Testing Complete, No trouble was found message appear?
    • No: There is still a problem. Contact your service provider. This ends the procedure.
    • Yes: Select Log Repair Action, if not previously logged, from the Task Selection menu to update the AIX error log. If the repair action was reseating a cable or adapter, select the resource associated with that repair action. If the resource associated with your action is not displayed on the resource list, select sysplanar0 and press Enter.
      Tip: This action changes the indicator light for the part from the fault state to the normal state.

      Go to step 9.

  7. Select the resource for the replaced part from the Resource Repair Action menu. When a test is run on a resource in system verification mode, and that resource has an entry in the AIX error log, if the test on the resource was successful, the Resource Repair Action menu appears. Complete the following steps to update the AIX error log to indicate that a system-detectable part has been replaced.
    Note: On systems with an indicator light for the failing part, this action changes the indicator light to the normal state.
    1. Select the resource that has been replaced from the Resource Repair Action menu. If the repair action was reseating a cable or adapter, select the resource associated with that repair action. If the resource associated with your action does not appear on the resource list, select sysplanar0 and press Enter.
    2. Select Commit after you make your selections. Did another Resource Repair Action display appear?
    • No: If the No Trouble Found display appears, go to step 9
    • Yes: Go to step 8.
  8. Select the parent or child of the resource for the replaced part from the Resource Repair Action menu if necessary. When a test is run on a resource in system verification mode, and that resource has an entry in the AIX error log, if the test on the resource was successful, the Resource Repair Action menu appears. Complete the following steps to update the AIX error log to indicate that a system-detectable part has been replaced.
    Note: This action changes the indicator light for the part from the fault state to the normal state.
    1. From the Resource Repair Action menu, select the parent or child of the resource that has been replaced. If the repair action was to reseat a cable or adapter, select the resource associated with that repair action. If the resource associated with your action does not appear on the resource list, select sysplanar0 and press Enter.
    2. Select Commit after you make your selections.
    3. If the No Trouble Found display appears, go to step 9.
  9. If you changed the service processor or network settings, as instructed in previous procedures, restore the settings to the values they had prior to servicing the system.
  10. Did you do any hot-plug procedures before doing this procedure?
    • No: Go to step 11.
    • Yes: Go to step 12.
  11. Start the operating system, with the system or logical partition in normal mode. Were you able to start the operating system?
    • No: Contact your service provider. This ends the procedure.
    • Yes: Go to step 12.
  12. Are the indicator lights still on?
