If no bootable image is found in the custom boot list, the server restarts and attempts
to boot again.
If the custom boot list is discovered to be damaged, the server rebuilds the custom
boot list according to the default boot list.
Loading Diagnostics in Service Mode Boot
The server can be booted in service mode (instead of normal mode) from either the
default boot list or custom boot list. After a successful service mode boot, the
diagnostic programs start automatically.
Diagnostics loaded from CD-ROM are called standalone diagnostics. Because the
default boot list checks the CD-ROM drive before it checks the disk drive, this
procedure is used to start standalone diagnostics.
Booting in Service Mode from the Default Boot List
To boot in service mode from the default boot list, do the following:
1. Before stopping the programs and operating system, notify your system
administrator and users that the server is going to be shut down.
2. Insert the diagnostics CD-ROM into the CD-ROM drive, if you intend to run
standalone diagnostics.
3. Turn off the server.
4. Wait 30 seconds, then turn on the server.
5. When the keyboard indicator appears during startup, press the F5 key if the
system console is a directly attached keyboard, or the 5 key if the system
console is an ASCII terminal.
6. Enter any passwords.
Booting in Service Mode from the Custom Boot List
Diagnostics loaded from a disk drive or network are called online diagnostics. (Online
diagnostics can be used only if the AIX operating system is installed.) Because the
custom boot list lists the disk drive or network device before the CD-ROM drive, this
procedure is used to start online diagnostics. To ensure that using the custom boot
list starts online diagnostics, do not insert the diagnostics CD-ROM.
To boot in service mode from the custom boot list, do the following:
