Oracle Netra SPARC T4-1B User Manual

14 Netra SPARC T4-1B Server Module Service Manual • June 2012
perform these tasks manually by setting the Oracle ILOM component_state or
fault_state of the faulted component. The procedure for clearing faults
manually is described in “Clear Faults (clear_fault_action Property)” on page 21.
Many environmental faults can automatically recover. For example, a temporary
condition might cause the computer room temperature to rise above the maximum
threshold, producing an overtemperature fault in the server module. If the
computer room temperature then returns to the normal range and the server
module’s internal temperature also drops back to an acceptable level, the SP will
detect the new fault-free condition. The SP will extinguish the Service Action
Required LED and clear the fault state from the FRU PROM.
The SP can automatically detect when a FRU is removed. In many cases, the SP does
this even if you remove the FRU while the SP is not running. This function enables
Oracle ILOM to sense that a fault, diagnosed to a specific FRU, has been repaired.
Note – Oracle ILOM does not automatically detect drive replacement. Oracle ILOM
does not automatically clear voltage sensor faults.
Oracle Solaris Fault Manager Commands in Oracle ILOM
The Oracle ILOM CLI includes a feature that enables you to access Oracle Solaris
fault manager commands, such as fmadm, fmdump, and fmstat, from within the
Oracle ILOM shell. This feature is referred to as the Oracle ILOM faultmgmt shell.
Drive Faults
PSH does not monitor drives for faults. As a result, the SP does not recognize drive
faults and will not light the fault LEDs on either the server module or the drive itself.
Use the Oracle Solaris message files to view drive faults. See “View System Message
Log Files” on page 24.
