HP-UX GSP (Guardian Service Processor)

Some old notes on GSP, first what is GSP?

GSP is a low level HP utility used for checking systems states on a HP/UX box. This document is to describe how to perform similar functions such as prtdiag on a Sun system. GPS is built in on most HP 9000 systems (L-Class/N-Class).

1. Login to the HP system on the console.

2. Once connected to the console, issue a ^b (control + b) to enter into the GSP.

3. Once you have been given the GSP prompt you can issue any of the following commands to get various types of diagnostic information:

cl – Shows you the messages displayed to the console on the last system boot. This is a useful command when trying to locate a system startup problem.

ps – Shows the current states of all the power supplies and fans. This is a useful tool when trying to locate a failed/failing power supply or fan.

ss – Shows the current states of the CPU installed in the machine. This command can be used in a similar fashion as ps with CPU's

sl – Show log information regarding events that have occurred on the system, that might not be logged in other areas. Events such as power failures and system temperatures being too high are logged here. Any event that could turn on the attention or warning lights would be stored here. By viewing the messages you will turn off the attention light, fault lights will stay on till the issue is resolved.

vfp – Virtual Front Panel shows you the current states of the lights on the front panel of the HP box which you are attached to.

4. To view a detail list of GSP commands you can enter HE at the GSP prompt.

5. To exit the GSP type co, which will return you the console.
