(such as USB CD-ROM or diskette drive) are assigned to the JS20 blade against which you are running diag -. Follow the prompts to resolve the resource conflict. See"Missing resources" on page 60 for more information. If an 8-digit error code is displayed, go to "Firmware error codes" on page 102, find the error and perform the listed action. If an SRN is displayed, record it and go to "SRN tables" on page 110. c. Then, proceed to the next step. 4. Complete these steps: a. At the command line, type diag and press Enter to move to the Function Selection menu. b. From the Function Selection menu, select Advanced Diagnostics Routines and press Enter. c. From the Diagnostic Mode Selection menu, select System Verification and press Enter. d. When the Diagnostic Selection menu appears, select All Resources, or test only the part you replaced, along with any devices that are attached to the part you replaced, by selecting the diagnostics for the individual part. Press F7 = commit to run the tests. Did the Resource Repair Action menu appear? No Go to Step 5. Yes Go to Step 6. 5. Did the ″Testing complete, no trouble was found″ display appear? No There is still a problem. Contact your service provider. This ends the procedure. Yes Complete the following steps: a. Press F3 or Enter to return to the Advanced Diagnostic selection, then press F3 or press the Esc key and the #3 key for the Function Selection menu. b. Select Task Menu. c. Select Log Repair Action 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 F7 = Commit. Note: This action changes the indicator light for the part from the Fault state to the Normal state. Go to Step 8 on page 32. 6. When a test is run on a resource in System Verification mode and that resource has an entry in the AIX error log, then, if the test on the resource was successful, the Resource Repair Action menu appears. After replacing a part, you must select the resource for that part from the Resource Repair Action menu. This updates 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 changes the indicator light from the Fault state to the Normal state. Follow these steps: a. 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 Chapter 5.
