reboot(2) Messages
The messages in this section may precede a
reboot(2)
, depending on the particular
PowerTrust configuration in the system.
NOTE
All of the reboot(2) messages will be followed by:
ups_mond: reboot -halt invoked due to UPS error cited in
previous syslog message.
MESSAGE
ups_mond: UPS <tty special file name> battery low
<
SEVERITY
Critical. The system is operating on insufficient reserve power.
MEANING
The PowerTrust device configured as <tty special file name> informed the UPS
Monitor that while it was operating on its battery to supply reserve power, the
battery drained down to a state of low charge. The PowerTrust unit has only
about two minutes of battery power remaining, after which the PowerTrust
output power will fail. If the specified PowerTrust unit is a critical PowerTrust
unit, then the system will reboot.
CAUSE
The PowerTrust unit detected a loss of AC power and switched over to its
battery reserve power to supply power to the system. The battery then drained
down to the point at which a "low charge" condition was detected, or the
battery had already been depleted by a previous AC power failure, and had not
had enough time to recharge.
ACTION
Locate the AC power loss problem, and restore that power to the system before
the battery becomes exhausted.
