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, while others might be accessible only from Standalone Diagnostics. Still
other programs might only be supported on a particular system architecture,
such as CHRP (Common Hardware Reference Platform) or RSPC (PowerPC
Reference Platform).
Note: If the system is running on a logically partitioned system, the following tasks may
only be executed in a partition with service authority:
v Configure Reboot Policy
v Configure Remote Maintenance Policy
v Configure Ring Indicate Power-On Policy
v Update System or Service Processor Flash
v Configure Scan Dump Policy
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 - Identifies the PCI RAID physical disks
v IdentifyRemove - 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.
