Configure Reboot Policy
This service aid controls how the system tries to recover from a system crash. Use this
service aid to display and change the following settings for the Reboot Policy.
Note: Some of the following settings might not be displayed by this service aid.
v
Maximum Number of Reboot Attempts
Enter a number that is 0 or greater.
Note: A value of 0 indicates ’do not attempt to reboot’ to a crashed system.
This number is the maximum number of consecutive attempts to reboot the system.
The term
reboot, 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 begins. The term restart, in the context of this service aid, is used
to describe the operating system activation process. Restart always follows a
successful reboot.
When a restart fails, and a restart policy is enabled, the system attempts to reboot
for the maximum number of attempts.
v
Use the O/S Defined Restart Policy (1=Yes, 0=No)
When ’Use the O/S Defined Restart Policy’ is set to Yes, the system attempts to
reboot from a crash if the operating system has an enabled Defined Restart or
Reboot Policy.
When ’Use the O/S Defined Restart Policy’ is set to No, or the operating system
restart policy is undefined, then the restart policy is determined by the ’Supplemental
Restart Policy’.
v
Enable 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.
v
Call-Out Before Restart(on/off)
When enabled, Call-Out Before Restart allows the system to call out (on a serial port
that is enabled for call out) when an operating system restart is initiated. Such calls
can be valuable if the number of these events becomes excessive, thus signalling
bigger problems.
v
Enable 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.
