Step 1542-4The system stopped with the Please define system console prompt appearing on the system console.Standalone diagnostics can be booted. Perform the following:1. Follow the instructions on the screen to select the system console.2. When the DIAGNOSTIC OPERATING INSTRUCTIONS screen is displayed, press Enter.3. If the terminal type has not been defined, you must use the Initialize Terminal option of the FUNCTIONSELECTION menu to initialize the AIX operating system environment before you can continue with thediagnostics. This is a separate and different operation from selecting the firmware console display.4. Select Advanced Diagnostic Routines.5. When the DIAGNOSTIC MODE SELECTION menu displays, select System Verification to rundiagnostics on all resources.Did running diagnostics produce a different symptom?NO Go to substep 6.YES Go to “Entry MAP” on page 61. Use the new symptom.6. Record any devices missing from the list of all adapters and devices. Continue with this MAP. Whenyou have fixed the problem, use this record to verify that all devices appear when you run SystemVerification.Are there any devices missing from the list of all adapters and devices?NO Reinstall all remaining adapters, if any, and reconnect all devices. Return the system to its originalconfiguration. Be sure to select fast-boot mode (select Enable Fast Boot) on the System PowerControl menu from the service processor main menu. Go to ″Map 0410: Repair Checkout″ in theRS/6000 Eserver pSeries Diagnostic Information for Multiple Bus Systems.YES The boot attempts that follow will attempt to isolate any remaining I/O drawer problems withmissing devices. Ignore any codes that may display on the operator panel unless stated otherwise.Go to “Step 1542-5”.Step 1542-5Examine the base system RIO port 0 of RIO connector card 1 (U0.1-P1-H1/Q1).Are there any I/O subsystems attached to the base system?NO Go to “Step 1542-18” on page 135.YES Go to “Step 1542-6”.Step 1542-6There may be missing devices associated with one or more I/O subsystems.Note: Before continuing, check the cabling from the base system to the I/O subsystem(s) to ensure thatthe system is cabled correctly. Refer to “Subsystem Positioning and Cabling” on page 41 for validconfigurations. Record the current cabling configuration and then continue with the following steps:1. Turn off the power.2. At the base system, disconnect the cable connection at RIO-2 port 0 (U0.1-P1/Q2).3. At the other end of the RIO-2 cable referred to in substep 2, disconnect the I/O subsystem portconnector 0 (U0.dd-P1.1/Q2). The RIO cable that was connected to RIO-2 port 0 in the base systemshould now be loose and can be removed. Record the location of this I/O subsystem.Chapter 3.
