System Startup, Configuration, and Shutdown Reference Manual (32650-90907)

Appendix H
Using the Guardian Service Processor (GSP)
Configuring the GSP
231
There is always one user listed for the local serial port. This is a default user name ("local user") if the local
console client user didn’t originate the GSP Command Interface session. If the local console operator typed
CTRL-B, then the login name that the local operator typed is displayed instead.

Security Options & access control (SO)
This command is used to modify the security parameters of the GSP. These include user accounts, login
timeouts, allowed password faults, etc. Most of the parameters are familiar; the following require some extra
explanation:
Dial-Back: If configured, when the user accesses the GSP via the modem port, the GSP will hang up and dial
the user back. This will not work if "Modem Presence" is set to "not always connected" in the CA command.
Mode: Single/Multiple. If the mode is Single, the State will be changed to disabled after the first login.
User’s State: Enabled/Disabled. A disabled user’s login will not be accepted (ADMINISTRATOR level
command).
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.
