IBM H80 Series manual Introducing Tasks and Service115 Aids

This number is the maximum number of consecutive attempts to reboot the

system. The trebootrm , in the context of this service aid, is used to describe bringing system hardware back up from scratch; for example, from a system reset or power-on.

When the reboot process completes successfully, the reboot attempts count is reset to 0, and a restart beginsrestart., Thein theerm context of this service

aid, is used to describe the operating system activation process. Restart a follows a successful reboot.

When a restart fails, and a restart policy is enabled, the system attempts reboot for the maximum number of attempts.

ŸUse the O/S Defined Restart Policy (1=Yes, 0=No)

When 'Use the O/S Defined Restart Policy' is set to Yes, the system attempt reboot from a crash if the operating system has an enabled Defined Restart Reboot Policy.

When 'Use the O/S Defined Restart Policy' is set to No, or the operating sy restart policy is undefined, then the restart policy is determined by the 'Supplemental Restart Policy'.

ŸEnable Supplemental Restart Policy (1=Yes, 0=No)

The 'Supplemental Restart Policy', if enabled, is used when the O/S Defined Restart Policy is undefined, or is set to False.

When surveillance detects operating system inactivity during restart, an enabled 'Supplemental Restart Policy' causes a system reset and the reboot process begins.

ŸCall-Out Before Restart (on/off)

When	enabled,		Call-Out	Before Restart allows the system to call out		(on	a ser
port	that	is	enabled for call-out)		when an operating system restart	is	initiate
Such	calls	can	be valuable if the		number of these events becomes	excessive,
thus	signalling		bigger	problems.

ŸEnable Unattended Start Mode (1=Yes, 0=No)

When	enabled, 'Unattended Start		Mode' allows	the	system to	recover from	the
loss	of	ac power.
If	the	system was powered-on	when the ac	loss	occurred,	the system	reboots

when power is restored. If the system was powered-off when the ac loss occurred, the system remains off when power is restored.

You can access this service aid directly from the AIX command line, by typing: /usr/lpp/diagnostics/bin/uspchrp -b
