Customizing SystemGuard For Your Needs

SystemGuard is controlled by several flags. The flags consist of Contract Flags, Operational
Flags, Remote Maintenance Flags, and Test Flags.

Remote Service Flag

This flag is disabled at the factory and must be enabled for remote service

Operational Flags

The Operational Flags are the

BUMP Console flag, the AutoService IPL flag, and Set Mode

to Normal When Booting flag, which are enabled at the factory, however, they can be
customized for your needs.

The

BUMP Console flag enables the SystemGuard Console attached to Serial Port 1. If

enabled, the console attached to Serial Port 1 is shared with the operating system. It is
recommended that this flag always be enabled if a console is attached to Serial Port 1. This
flag can be set from the Set Flags menu, MISCELLANEOUS PARAMETERS menu, or the
Service Aids.

The

AutoService IPL flag instructs SystemGuard to bypass the MAINTENANCE MENU

when the system is booted in Service Mode. This enables the system to be booted quicker
when installing the operating system and when loading the diagnostics. It is recommended
that this flag always be enabled unless there is a need to use the MAINTENANCE MENU.
This flag can be set from the Set Flags menu, MISCELLANEOUS PARAMETERS menu, or
the Service Aids.

The

Set Mode to Normal When Booting flag instructs SystemGuard to reset the Electronic

Key to Normal when booting. It is recommended that this flag always be enabled. This flag
can be set from the MISCELLANEOUS PARAMETERS menu or the Service Aids.

Test Flags

The Test Flags are the

Boot Multiuser AIX in Service flag, Fast IPL flag, Extended Tests flag,

PowerOn Tests in Loop Mode flag, and PowerOn Tests in Trace Mode flag. They are
disabled at the factory. They are used during testing and do not need to be customized.

Remote Maintenance Flags

The Remote Maintenance Flags are the

Remote Authorization flag, Dial-Out Authorization

flag, and

Electronic Mode Switch from Service Line flag. They are disabled at the factory,

however, they can be customized for your needs.

The

Remote Authorization flag enables the SystemGuard Console to use Serial Port 2 for a

Remote Console and to report problems to a remote site. If enabled, Serial Port 2 is shared
with the operating system. The setting of this flag depends if you are using remote
maintenance or not. This flag can be set from the Set Flags menu, MISCELLANEOUS
PARAMETERS menu, or the Service Aids.

The

Dial-Out Authorization flag enables the SystemGuard Console to report problems that

prevent the system from booting to be reported to a remote site via Serial Port 2. The setting
of this flag depends if you are using remote maintenance or not and if you want problems
that prevent the system from booting to be reported to a remote site. This flag can be set
from the Set Flags menu, MISCELLANEOUS PARAMETERS menu, or the Service Aids. If
this flag is enabled, a Service Center Dial-Out phone number must be set.

The

Electronic Mode Switch from Service Line flag enables the Electronic Mode Switch to

be controlled from the Service Console. The setting of this flag depends if you want the
Electronic Mode Switch to be controlled from the Service Line or not. This flag can be set
from the MISCELLANEOUS PARAMETERS menu or the Service Aids.
