Chapter 6. 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 4.2 and later.

Note: Many of the tasks and service aids work on all system model architectures. Some are only accessible from online diagnostics in service or concurrent mode, while others might be accessible only from standalone diagnostics. Your system uses an architecture known as CHRP (Common Hardware Reference Platform). The tasks and service aids identified in this chapter work on CHRP architected systems.

To perform a task, begin by using 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 -Tflag. 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:

vCertify - Certifies media

vChkspares - Checks for the availability of spare sectors

vDownload - Downloads microcode to an adapter or device

vDisp_mcode - Displays current level of microcode

vFormat - Formats media

vIdentify - Identifies the PCI RAID physical disks

vIdentifyRemove - 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.
