System Startup, Configuration, and Shutdown Reference Manual (32650-90892)

244 AppendixH
Using the Guardian Service Processor (GSP)
Configuring the GSP
Remote Power Control (PC)
For proper system shutdown, shut down the OS before issuing this command.
This command allows the user to switch the system power ON or OFF, or Power Cycle the
machine. The user can have the action take place immediately, or after a specified delay.
Note this is roughly equivalent to turning the system power off at the front panel switch.
There is no signal sent to the OS to bring the software down before power is turned off. To
turn the system off properly, the operator must ensure that the OS is in the proper
shutdown state before issuing this command, by using the proper OS commands.

Diagnostic and/or Reset of GSP (XD)
This command allows the user to perform some simple checks to confirm the GSP's health
and its connectivity status. The following tests are available:
• Parameters checksum
• I2C bus test
• LAN connectivity test using "ping"
• Modem self-tests
Also, the GSP can be reset from this command. A GSP reset can be safely performed
without affecting the operation of the server.
Upgrade the GSP Firmware (XU)
The upgrade is performed using ftp over the GSP LAN, which must therefore be
operational. The user must enter the ftp server IP address, login, password, and the
directory in which the upgrade files reside. If an upgrade is required, contact your HP
Representitive to get the location and logon to the server where the upgrade files reside.
When the command is initiated, the LAN and modem connections will be dropped. The XU
command can only be run from the local port. If the upgrade is successful, the GSP will
reboot and come up using the new software.
If the upgrade fails, the GSP will return to the prompt with instructions on what went
wrong, and what to do next.
Upgrading the GSP software and rebooting the GSP can be safely performed without
affecting the operation of the server.
The version of GSP firmware is displayed at the top of the main help menu.
Virtual Front Panel Display (VFP)
When invoked, the VFP will display the LED state with a text decode and the most recent
Chassis Code received. At that point, the user can then proceed with the live-mode VFP
display of chassis codes, or quit back to the GSP prompt.
There are two ways that the live display of chassis codes can be started:
