6. Enter any passwords.
Diagnostics loaded from CD-ROM are called standalone diagnostics. Because the
default boot list checks the CD-ROM drive before the disk drive, this procedure is
used to start standalone diagnostics.
Booting in Service Mode from the Custom Boot List
To boot in service mode from the custom 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. Turn off the server.
3. Wait 30 seconds, then turn on the server.
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.) 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.
