GSP Logging Capabilities
The introduction of GSP to the above platforms dramatically changes the way chassis
operations and diagnostic evaluations are performed on a running system.
The new subsystem requires HP-UX to provide more information than was provided on
previous platforms. HP-UX will continue to output the same chassis-codes and
forward-progress indicators that have been provided in previous releases. On the above
and subsequent systems, however, the codes are displayed on the Virtual Front Panel
(VFP) of the system. Most of the existing four-hex digit chassis codes are enclosed in
GSP-specific encoding.
The GSP subsystem interprets various forms of logging information from both firmware
and software. Several new software events are now logged, including:
•“Boot Complete” indicator
• Timestamp
• Periodic heartbeat, with:
— timeout value (a time-limit within which another event must be logged before
the system is declared “dead”)
— activity level indicating system usage
• Minimal LED control
In addition to existing four-hex digit chassis codes, the following information is sent with
each event:
• Alert level
• CPU number
NOTE The GSP will not store codes of alert level 0 after PDC's “boot complete” code. All
incoming codes will display on the VFP, but level 0's will not be stored for later retrieval.
This is so the log won't fill up with heartbeat entries.
PDC_CHASSIS, the old firmware call for old-style, four-hex digit chassis codes, always
produces codes of alert level 0. In order to create new-style chassis codes, the PAT_ call
for CHASSIS must be used.
