Solution 1570898.1 : NETRA T3/4-X CRITICAL_ALARM ON when O.S. not running

Applies to:

Netra SPARC T4-1 Server - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.

Symptoms

The Critical Alarm is ON in Netra T3/4 servers when Solaris is not running. The following status is displayed:

-> cd /SYS/CRITICAL_ALARM/
/SYS/CRITICAL_ALARM

-> show

/SYS/CRITICAL_ALARM
   Targets:

   Properties:
       type = Indicator
       ipmi_name = CRITICAL_ALARM
       value = On

   Commands:
       cd
       set
       show

We can turn off the led but after SP reset LED comes ON again.

->set /SYS/critical_alarm value=off

Cause

This is a normal behavior for the Netra product line. Netra server Firmware can only modify the Critical Alarm & does not modify the other Alarms. The critical Alarm is raised since the customer's application is not operational when the OS is not operational. The customer's application could set this Alarm when a major problem occurs, but cannot if the OS is down so is why Firmware raises this Alarm.

Solution

The Critical Alarm will be turn off when Solaris becomes operational.
