HP-UX 11i June 2001 Release Notes

Workstation/Server Specific Information
Guardian Service Processor (GSP)
Chapter 356
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 will be 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.
