Using Chassis Code Log Viewers
The service processor’s chassis log viewer enables you to view chassis
codes that are emitted throughout the entire server complex.
To enter the chassis log viewer enter SL at the service processor Main
menu. To exit the viewer type ^b (Control-b) to return to the Main menu.
Chassis codes are data that communicate information about system
events from the source of the event to other parts of the server complex.
Chassis code data indicates what event has occurred, when and where it
happened, and its severity (the alert level).
All chassis codes pass from the event source through the service
processor. The service processor takes any appropriate action and then
reflects the chassis codes to all running nPartitions. If an nPartition is
running event monitoring software, it may also take action based on the
chassis codes (for example, sending notification e-mail).
System administrators, of course, may have interest in viewing various
chassis codes—especially chassis codes that indicate failures or errors.
Hardware, software, and firmware events may emit chassis codes as a
result of a failure or error, a major change in system state, or basic
forward progress. For example: a fan failure, an HPMC, the start of a
boot process, hardware power on or off, and test completion all result in
chassis codes being emitted.
While HP-UX is running on an nPartition it constantly emits a
“heartbeat” chassis code (at alert level 0) to indicate that the operating
system still is functioning and has not hung.
NOTE Each nPartition server cabinet’s front panel attention LED is
automatically turned on when one or more chassis codes of alert level 2 or
higher have not yet been viewed by the administrator. When this
attention LED is on, entering the chassis log viewer turns the LED off.
You can remotely check this attention LED’s on/off status by using the
service processor Command menu’s PS command, G option.
