Chapter 8. General AIX and xSeries standalone diagnostic information This chapter describes standalone diagnostics for AIX and running the standalone diagnostics from CD-ROM. Information for general diagnostic systems running the AIX operating system Information for general diagnostic systems running the AIX operating system is provided in this section. For information about standalone CD AIX diagnostics, see "Running the standalone diagnostics from CD-ROM" on page 25. Information in this section is common to all JS20 system units. Any service information or diagnostic procedure that is specific to a system unit or device is a separate procedure for that system unit or device. AIX operating system message files English is the default language displayed by the diagnostic programs when run from disk. If you want to run the diagnostic programs in a language other than English, you must install on the system the AIX operating system message locale file set for the desired language you want displayed. AIX diagnostic and the standalone diagnostic tasks provide the capability to display device and adapter microcode levels as well as update device and adapter microcode. AIX diagnostic tasks also provide the capability to update firmware. Use the Update and Manage System Flash task to update a system's firmware. When the flash update is complete, the system automatically reboots. Microcode images can be installed from disk, diskette, or NIM server. For additional information, refer to "Update and manage system flash using AIX diagnostics" on page 52. Use the microcode download for systems using AIX 5.2.0.30 or later task to install microcode onto devices and adapters. This task presents a list of resources that are currently installed and supported by this task. Microcode images can be installed from disk, diskette, or NIM server. For additional information, refer to "Download microcode" on page 64. For adapters and devices with microcode that can be updated but are not supported by this task, refer to the manufacturer's instructions. For systems not using AIX, these tasks can be used via the "Running standalone diagnostics from a management (NIM) server" on page 68. Otherwise, refer to the corresponding documentation for the operating system on installing microcode. CE login CE login enables a user to perform operating system commands that are required to service the system without being logged in as a root user. CE login must have a role of Run Diagnostics and a primary group of System. This enables the user to: v Run the diagnostics including the service aids, certify, format, and so forth. © Copyright IBM Corp. 2003 59
