Working with Standalone versus Online Diagnostics
When the server attempts to boot in service mode (from either the default or custom
boot list) and locates a diagnostics CD-ROM before any other bootable image, then
the server starts standalone diagnostics.
Standalone diagnostics can be used on servers installed with any supported
operating system.
When the server attempts to boot in service mode (from either the default or custom
boot list) and first locates a bootable image on disk drive or network connection, then
the server starts online diagnostics.
Online diagnostics can be used only on servers installed with the AIX operating
system.
Because the type of diagnostics started (standalone or online) depends on the
source from which they are loaded, changing the boot list used during system startup
can affect which diagnostics are run.
Recommended Boot Options
The procedures under “Loading Diagnostics in Service Mode Boot” on page 2-7
produce the following recommended results:
Default boot list (F5 or 5 key) with diagnostics CD-ROM inserted loads
Standalone Diagnostics.
Custom boot list (F6 or 6 key) without diagnostics CD-ROM inserted loads Online
Diagnostics, if AIX is installed on a device in the custom boot list.
