manage the machine-wide settings using the ASMI and allows complete system and partition
management from the HMC. Also, the surveillance function of the SP is monitoring the
operating system to check that it is still running and has not stalled.
Figure 3-2 shows an example of the ASMI accessed from a Web browser.

3.2.2 Partition diagnostics
The diagnostics consist of stand-alone diagnostics, which are loaded from the DVD-ROM
drive, and online diagnostics (available in AIX 5L):
Online diagnostics, when installed, are resident with AIX 5L on the disk or server. They
can be booted in single-user mode (service mode), run in maintenance mode, or run
concurrently (concurrent mode) with other applications. They have access to the AIX 5L
error log and the AIX 5L configuration data:
– Service mode (requires service mode boot) enables you to check system devices and
features. Service mode provides the most complete checkout of the system resources.
All system resources, except the SCSI adapter and the disk drives used for paging,
can be tested.
Note: The IBM System p5 service processor enables the analysis of a system that does
not boot. It can be performed either from ASMI, an HMC, or an ASCI console (depending
on the presence of an HMC). ASMI is provided in any case.
