Chapter 6. Introduction to 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 these programs work on all system model architectures. Some
programs are only accessible from Online Diagnostics in Service or Concurrent
mode, others may be accessible only from Standalone Diagnostics, while still
other programs may only be supported on a particular system architecture, such
as CHRP (Common Hardware Reference platform).
Use the FUNCTION SELECTION menu to perform tasks.
Once a task is selected, a resource menu may be presented
You can use a fast-path method to perform a task by using the diag command and the
-T flag. This means the user does not have to go through most of the introductory
menus just to get to a particular task. Instead, the user is presented with a list of
resources available to support the specified task. The fast-path tasks are:
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 - identifies the PCI RAID physical disks.
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.
