Issue 3 April 2000 386

uptime

— This option specifies the amount of time that the

system must be in service before the automatic reboot feature is
activated. The default is 5 minutes.

status

— This option shows the current values of the automatic reboot

parameters, plus the number of unanticipated reboots that occurred in the

window

minutes preceding the most recent system boot.

When the auto-reboot feature is enabled and activated, the system
automatically reboots after a UNIX panic. The auto-reboot feature is activated
as follows:

If there were fewer

reboots

than unanticipated reboots during the

window

minutes prior to the most recent system boot, the automatic reboot feature is
activated (if enabled)

uptime

minutes after the most recent system boot.

For example, assume the automatic reboot parameters are set to their default
values. A system crash occurs. The system reboots at 8:00. If there were
fewer than five unanticipated reboots between 7:00 and 8:00, the auto-reboot
feature is activated as 8:05. Otherwise, it is activated at 9:00.

An unanticipated reboot is a system boot that occurs after a system crash. A
system crash can be caused, for example, by a UNIX panic, a system restart
via

R E S E T,

or a sudden power loss.
