The diagnostics cannot be loaded on a system (client) from a server if that
system is not set up to boot from a server over a network. When the system is
set up to boot from a server, the diagnostics are run in the same manner as they
are from disk.
If the diagnostics are loaded from disk or a server, you must shutdown the AIX
operating system before turning the system unit off to prevent possible damage
to disk data. This is done in one of two ways:
– If the diagnostics were loaded in standalone mode, press the F3 key until
DIAGNOSTIC OPERATING INSTRUCTIONS displays; then press the F3 key
once again to shutdown the AIX operating system.
– If the diagnostics were loaded in maintenance or concurrent mode, enter the
shutdown -F command.
Under some conditions the system may stop, with instructions displayed on
attached displays and terminals. Follow the instructions to select a console
display.
Your system unit must be configured to receive boot over the network or the
server must be setup to send a service mode boot of the diagnostics.
Running the Diagnostics from a TTY Terminal
Consider the following when you run diagnostics using a TTY-type terminal as the
console display:
See the operator manual for your type of tty terminal to find the key sequences
you need to respond to the diagnostics.
When the diagnostics present display information through the Serial 1 port,
certain attributes are used. These attributes are set as if the diagnostics were
using a 3161 display terminal. The following tables list attributes for the 3161
ASCII Display Terminal and for two other ASCII display terminals commonly
used with the system.
If you have a TTY terminal other than a 3151, 3161 or 3164 attached to the
Serial 1 port, your terminal may have different names for the attributes. Use the
attribute descriptions in the following tables to determine the settings for your
terminal.
