Booting in Service Mode from the Custom Boot List
To boot in service mode from the custom boot list, do the following:
1. Verify with the system administrator and users that all programs are to be
stopped, then do so.
2. Turn off the system.
3. Wait 30 seconds, then turn on the system.
4. When the keyboard indicator appears during startup, press the F6 key if the
system console is a directly-attached keyboard, or the 6 key if the system
console is an ASCII terminal.
5. Enter any passwords.
Diagnostics loaded from a disk drive or network are called online diagnostics.
(Online diagnostics can be used only if AIX is installed.) Since the custom boot list
should list 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.
