Introducing tasks and service aids The AIX diagnostic package contains programs that are called Tasks. Tasks can be thought of as performing a specific function on a resource; for example, running diagnostics or performing a service aid on a resource. This chapter describes the tasks available in AIX Diagnostics version 5.2 and later. Notes: 1. Some programs are only accessible from Online Diagnostics in Service or Concurrent mode, while others might be accessible only from Standalone Diagnostics. 2. The specific tasks available will be dependent on the hardware attributes or capabilities of the system you are servicing. Not all service aids or tasks will be available on all systems. To perform one of these tasks, use the Task Selection option from the Function Selection menu. After a task is selected, a resource menu may be presented showing all resources supported by the task. A fast-path method is also available to perform a task by using the diag command and the -T flag. By using the fast path, the user can bypass most of the introductory menus to access a particular task. The user is presented with a list of resources available to support the specified task. The fast-path tasks are as follows: v Certify - Certifies media v Chkspares - Checks for the availability of spare sectors v Download - Downloads microcode to an adapter or device v Disp_mcode - Displays current level of microcode v Format - Formats media v Identify Remove - Identifies and removes devices (hot-plug). To run these tasks directly from the command line, specify the resource and other task-unique flags. Use the descriptions in this chapter to understand which flags are needed for a given task. Task and service aid functions If a device does not show in the test list or you suspect that a device's diagnostic package is not loaded, check by using the Display Configuration and Resource List task. If the device you want to test has a plus (+) sign or a minus (-) sign preceding its name, the diagnostic package is loaded. If the device has an asterisk (*) preceding its name, the diagnostic package for the device is not loaded or is not available. Tasks and service aids provide a means to display data, check media, and check functions without being directed by the hardware problem determination procedure. Refer to "Tasks (service aids)" on page 63 for a list of tasks and service aids. AIX automatic error log analysis (diagela) Automatic error log analysis (diagela) provides the capability to perform error log analysis when a permanent hardware error is logged by enabling the diagela program on all RPA platforms. The diagela program determines if the error should be analyzed by the diagnostics. 62 BladeCenter JS20 Type 8842: Hardware Maintenance Manual and Troubleshooting Guide
