FAN FAILURE BEHAVIOR IN SUN FIRE V890 SERVER
=========================================

Only the primary fan trays are running during normal system operation. If a primary fan tray fails, the environmental monitoring subsystem detects the failure and automatically activates the secondary fan tray.

If any primary fan fails, the monitoring subsystem detects the failure and performs the following:

■Generates an error message and logs it in the /var/adm/messages file
■Lights the System Fault and Thermal Fault LEDs on the status and control panel
■Lights the appropriate Fan Fault LED inside the system
■Automatically activates the appropriate secondary fan tray (if enabled )

Symptoms


Issue reported as follows

During a walk-through it was noted that the ATTENTION LIGHT ON and HIGH TEMP ALARM were on.
