7. If any SRNs or firmware error codes are displayed, record all information provided from the diagnostic results, go to the "SRN tables" on page 110 or "Firmware error codes" on page 102. If ″No trouble found″ is displayed, continue to the next step. 8. When testing is complete, press F3 to return to the Diagnostic Operating Instructions display. 9. Press Ctrl+D to log off from root user or CE login. When finished, contact your hardware service provider with any information you received during the diagnostics, including service request numbers (SRNs) or firmware error codes. Verifying the replacement part using AIX diagnostics Complete the following steps to verify the replacement part using AIX diagnostics: 1. Did you use an AIX or online diagnostics service aid hot-swap operation to replace the part? Note: When you are not sure, answer this question No. No Go to Step 2. Yes Go to Step 4 on page 31. Note: Hot plug is currently not supported on the JS20. 2. Follow these steps: a. Start the system. b. Wait until the AIX operating system login prompt displays or until apparent system activity on the operator panel or display has stopped. Did the AIX login prompt display? No If an SRN displays, 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. Contact your service provider for assistance. Note: If you received an SRN or any other reference code when you attempted to start the system, you can learn more about these codes in the "SRN tables" on page 110 or "Firmware error codes" on page 102. This ends the procedure. Yes Go to Step 3. 3. If the Resource Repair Action menu appears, go to Step 6 on page 316. If not, follow these steps: a. Log in as root user or use CE login b. At the command line, type diag -a and press Enter to check for missing resources. Follow any instructions that appear. If an SRN displays, suspect a loose card or connection. If no instructions appear, no resources were detected as missing; go to Step 4 on page 31. Note: If you have a resource with a "-M", this means the resource is no longer available to this JS20 blade.
