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.
Once the Maximum Number of Reboot Attempts is exceeded, the system will call
out if that function has been enabled.
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 serivice
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 will attempt to
reboot for the maximum number of attempts.
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 will attempt
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'.
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.
Call-Out Before Restart (on/off)
When enabled, Call-Out Before Restart will allow 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.
Enable Unattended Start Mode (1=Yes, 0=No)
When enabled, 'Unattended Start Mode' will allow the system to recover from the
loss of AC power.
If the system was powered-on when the AC loss occured, the system will reboot
when power is restored. If the system was powered-off when the AC loss
occured, the system will remain off when power is restored.
