Current Default Situation

A Power Supply failure on Sun StorEdge[TM] A1000 and Sun StorEdge[TM]
A3000/A3500 disk subsystems currently results in no alarm. The equipment
has to be physically inspected periodically to detect power supply failures
in one of the redundant power supplies.

Although these systems have redundant power supplies there is no current
method to notify anyone that one of the supplies have failed. Without
periodic inspections, the failure of a second power supply would be
catastrophic.

How to enable Power Supply failure monitoring

RAID Manager (RM6) software that controls and monitors the Sun StorEdge
A1000 and Sun StorEdge A3000/A3500. RAID arrays have a utility that
performs a "health check" on the entire storage enclosure. By creating an
hourly cronjob on the RM6 server an administrator can capture power supply
failure notifications.

An administrator could execute;

 /usr/lib/osa/bin/healthck - a | grep Pwr >>/var/adm/messages

and have any arrays controlled by RM6 software place any power supply
failures that happened within the hour into the RM6 server's
"/var/adm/messages" file. The format of these messages would be:

 Servername" Drive Tray-Pwr Supp Failure

The "var/adm/messages" file can then be reviewed on a regular basis to
detect when one of the redundant power supplies has generated a failure
message. The appropriate repair actions could then be performed on or
during a scheduled maintenance window.
