2-18 Sun Blade T6320 Server Module Service Manual • June 2009
Many environmental faults can automatically recover. For example, a temperature
that is exceeding a threshold might return to normal limits, when you connect a
fan. The recovery of environmental faults is automatically detected. Recovery
events are reported using one of two forms:
■ fru at location is OK.
■ sensor at location is within normal range.
There are three thresholds for an environmental fault:
■ Warning: ILOM issues a command to burst the fan speed.
■ Soft shutdown: ILOM initiates a graceful shutdown.
■ Hard shutdown: Immediate shutdown.
Environmental faults can be repaired through hot removal of the faulty FRU. The
FRU removal is automatically detected by the environmental monitoring and all
faults associated with the removed FRU are cleared. The message for that case,
and the alert sent for all FRU removals is:
fru at location has been removed.
■ Fault repair – The fault has been repaired by human intervention. In most cases,
ILOM detects the repair and extinguishes the Service Required LED. In the event
that ILOM does not perform these actions, you must perform these tasks
manually with the following commands:
■ set /SYS/clear_fault_action=true (The ALOM-CMT equivalent is
clearfault) Clears the PSH fault logs but does not enable the component.
See Section 2.7.2, “Clearing PSH Detected Faults” on page 2-45.
■ set /SYS/component/component_state=enabled (The ALOM-CMT
equivalent is enablecomponent) Clears POST generated faults and enables
the component. See Section 2.6.4, “Clearing POST Detected Faults” on
page 2-39.
2.5 Using the ILOM Web Interface For
Diagnostics
These instructions use the ILOM web interface. To use the command line interface
(CLI), see Appendix D of this manual, theSun Integrated Lights Out Manager 2.0
Supplement for Sun Blade T6320 Server Modules, or the Sun Integrated Lights out
