GSP Notes

To see what's recently changed on this page - please look at the Changes page.

This is a bunch of notes on how to use the GSP function of your HP server. To use, go to your console and hit Ctrl-b to enter the GSP funhouse.

Other pages of mine that may be of interest:
Unix Notes, Server Build document, Ignite document, /etc/inetd.conf document


Command line fun:
You can check the GSP from the command line by running this command: stty +queryGSP < /dev/GSPdiag1
It should come back with "GSP is functional".

You can reset the GSP from the GSP (see below), but if it's hung you'll need to reset it from the command line. Run the following command on the command line to "reboot" the GSP (without rebooting the server):

stty +resetGSP < /dev/GSPdiag1
When you run this command you will get a prompt on the console: "Press 'p' now to clear all GSP passwords and users...". If you press "p" and then confirm it (you only have a few seconds to respond), the GSP user/password info is wiped. Your LAN info is kept however.

On some servers you have a tiny button on the back of the server. Press it using a pen, pencil, or paper clip. This will also reboot the GSP.

Generic login and password is either: Admin Admin or <Enter> <Enter> (blank blank - in other words)

Other Stuff...
Look at my Server Build page in order to see the GSP internal web console configuration.

GSP Help Overview

The Guardian Service Processor (GSP) is an independent support processor for the system console. GSP provides services that facilitate the management of the host system. Its major features are:

top

GSP MODES

THE MIRRORED GSP SESSION:

When first logging on, the user is part of the mirrored GSP session. The mirrored GSP session has three modes:
  1. GSP Command Mode -
    You are in the GSP Command Mode right now. In this mode all the GSP commands can be executed. Typically this mode is entered by typing CTRL-B from console mode.

  2. Console Mode -
    In Console Mode the user gets access to the Unix console. This mode is entered from the GSP Command Mode using the (
    CO) command.

  3. VFP or Alert Mode -
    In the VFP or Alert Mode the GSP displays a representation of the front panel leds, called the Virtual Front Panel (VFP). This mode is entered from GSP Command Mode using the VFP command.
See the help on those commands for more information.

LEAVING MIRRORED GSP SESSION:

From the local or remote/modem ports, it is also possible to leave the mirrored GSP session and connect to either the OS (see the SE command) or to another GSP on the network (see the CSP command).

top

GSP COMMAND HELP

The GSP commands can be grouped into the following categories: top

OPERATOR / ADMINISTRATOR HELP

Administrators have more capabilities than Operators.

Administrator-Only Commands:

AR
(Automatic system Restart)
DC
(Default Configuration)
IT
(Inactivity Timeout)
LC
(LAN Configuration)
PG
(PaGing)
SO
(Security Options)

The GSP Command interface permission/access level:

The GSP Command interface permission/access level is set by the first user that types CTRL-B to initiate it. If that user is an operator- user, then the command interface runs at operator access level. Even if an administrator-user logs in later or the operator-user disconnects, the access level stays the same. The access level can be changed by leaving GSP command mode and typing CTRL-B again to return.

top

CONSOLE MODE HELP

Typing "CO" from the GSP Command interface provides a mirrored version of the OS console. All mirrored users see the same output. At any time, only one of the mirrored users has write access to the console. To get write access to the console, type CTRL-e c f (not CTRL-e CTRL-c CTRL-f).

SEE ALSO: CO (COnsole)

top

SESSION MODE HELP

Typing "SE" from the GSP Command interface provides a non-mirrored, normal OS login. The session is not the console; it is a separate login to the OS, and the messages that the OS sends to the console will not be seen.

RECOMMENDATION: Use the session for ASCII screen-oriented applications (SAM) or file transfer programs (ftp) from the local or modem ports. To use these applications from the LAN, telnet directly to the system for a private login.

SEE ALSO: SE (SEssion)

top

CHASSIS CODES

Chassis codes are encoded data that provide system information to the user. Some well-known names for similar data would be Event Logs or Post Codes. Chassis codes are produced by intelligent hardware modules, the O/S, and system firmware. Use VFP to view the live chassis codes. Use SL to view the chassis code log.

The following severity (or alert) levels are defined:
0. No failure 6. Pending failure 11. (Reserved)
1. Information only 7. (Reserved) 12. Software Failure
2. Non-urgent attention req. 8. Performance Impaired 13. System hang
3. System blocked 9. (Reserved) 14. Power failure
4. Unexpected configuration 10. Loss of Functionality 15. Fatal HW failure
5. Environmental problem

SEE ALSO: SL, VFP (Show Logs, Virtual Front Panel)

top

PORTS HELP

The local, remote/modem, and LAN ports are actual connections on the back of the server. All ports can be used even when the server is non-functional.

  1. Local port -
    Provides serial port terminal access. To configure, see the
    CA (Configure Asynchronous) command.

  2. Remote/Modem port -
    Provides external modem access. Related commands are ER, MS, and MR (Enable Remote/modem, Modem Status, Modem Reset)

  3. LAN port -
    Provides telnet and web access into the GSP. Related commands are EL, LC, and LS (Enable LAN, LAN Configuration, and LAN Status).

top

REMOTE/MODEM PORT HELP

The remote/modem port can be used for dial-in access to the GSP or the OS, and can be configured so that the OS or the GSP can activate a pager.

The remote/modem port is configured via the CA command. The ER command enables/disables the port and gives the modem control over to the GSP or the OS. See the help on those commands for more details.

SEE ALSO: CA, ER, DI, MR, MS, PG (Configure Asynchronous, Enable Remote, DIsconnect remote or LAN, Modem Reset, Modem Status, PaGing)

top

INTERNAL PORT HELP

The Internal Port has been obsoleted.

top

HPTERM & VT100 HELP

RECOMMENDATION: Do not mix HP and vt100 terminal types at the same time.

The GSP mirrors the system console to the GSP local, remote/modem, and LAN ports. One console output stream is reflected to all of the connected console users. If several different terminal types are used simultaneously by the users, some users may see strange results.

HP-UX example:
Applications which care about the terminal type (install, SAM, vi, etc.) running on HP-UX use three methods to determine the terminal type:

  1. The application takes the terminal information from the OS. This value is set in the CA command and takes effect for all GSP ports.
  2. The $TERM shell environment variable
  3. The application directly queries the terminal (in this case, the write enabled terminal will establish the terminal type.)
Make sure that settings #1 and #2 agree with your terminal type.

MPE/iX Example:
MPE/iX only supports HPTERM terminal type. If the terminal type is set to VT100 there may be unpredictable results when some applications are run.

Applications which care about terminal type are of three categories:

  1. Block mode applications using VPlus such as NMMGR.
  2. Other screen oriented applications such as HPEdit.
  3. Applications running under the MPE/iX Posix environment.

The application categories #1 and #2 generally get the terminal type by querying the terminal. The MPE/iX Posix applications will use the $TERM shell variable.

top

PASSWORDS: HOW TO RESET

There are several ways to reset passwords in the GSP:
  1. In the SO command, change individual users
  2. In the DC command, choose \"Reset Security configuration\"
  3. If all passwords have been forgotten, they can be reset by hitting the reset button on the back panel of the GSP. After the GSP reboots, the local console terminal will display a message for five seconds. Responding to this message in time will allow a local user to reset the passwords.

Note that the user information as well as the passwords are erased in methods 2 & 3.

SEE ALSO: DC, SO (Default Configuration, Security Options)

GSP Commands


General Configuration
AC : Alert display Configuration

The GSP will automatically activate the ALERT DISPLAY when a chassis code with an alert level greater than or equal to the configured threshold is received. Users in console mode or GSP command mode will be returned to console mode after the alert is acknowledged. Users in VFP mode will be returned to VFP mode.

Alerts with level 2 or greater will go into the Error Log. If an alert is acknowledged in the ALERT DISPLAY, that alert will not light the Attention LED. Any unacknowledged alert in the Error Log will light the Attention LED. To turn off the LED, read the Error Log. Since level 2 alerts can never activate the ALERT DISPLAY, they must always be acknowledged by reading the Error Log.

The setting in AC has no affect on the automatic early boot VFP. During boot, level 3 alerts and greater will always be displayed.

SEE ALSO: SL, VFP (Show Logs, Virtual Front Panel)

top

General Configuration
AR : Automatic System Restart configuration

The AR command allows the operator to enable, disable, and configure the Automatic System Restart (ASR). ASR is triggered by each alert level value that is configured. For instance, for levels 12 and higher, you would specify alerts "12 13 14 15" for the triggering condition.

The default is level 13. Setting ASR for alert levels below 10 is strongly discouraged.

(ADMINISTRATOR level command.) SEE ALSO: DC (Default Configuration)

top

Port Configuration
CA : Configure Asynchronous local and remote serial ports

BAUD RATES: Input and output data rates are the same.

FLOW CONTROL: Hardware uses RTS/CTS; Software uses Xon/Xoff. TERMINAL TYPE: See subject "HPterm", (next page)

TRANSMIT CONFIGURATION STRINGS: Disable this setting whenever the modem being used is not compatible with the supported modem (MT5634ZBA).

MODEM PRESENCE: Set this to "not always connected" when the modem may not always be connected. For example: A modem attached through a switch. In mode "not always connected", no dial-out functions are allowed: DIAL-BACK is disabled, and PAGING is not possible.

MODEM PROTOCOL: CCITT is a European standard; RTS/CTS signaling is used, as well as the Ring signal. Bell is a U.S. or simple mode.

SEE ALSO: ER (Enable Remote/modem)

top

Status
CE : Chassis Entry- Put a repair log entry in the log history

Allows a CE to add an entry to the chassis logs, usually to indicate a firmware update or repair. The command prompts for a one-line text message. The message will be logged to the Error Log.

SEE ALSO: AC, SL (Alert Configuration, Show Logs)

top

Status
CL : Console Log- view the history of the Console output

This command displays up to 20 Kilobytes of logged console data (about 20 pages of display in text mode) sent from the system to the Console path.

SEE ALSO: CO (COnsole)

top

Connection
CO : COnsole- leave command mode and return to console mode

This command exits the GSP command interface, and connects to the system console. All mirrored users are switched. Type CTRL-B to return to the GSP command interface.

VT100 and HPTERM: Verify that the GSP setting in the CA command is correct and all mirrored consoles are of the same terminal type for proper operation.

To run an ASCII screen-oriented application (SAM) or a file transfer program (ftp), the console is not the recommended connection. On the local or remote/modem ports, it is recommended that the SE command be used to start a private system session, so that console output and mirroring do not disrupt the application. On the LAN, connecting directly via telnet or web to the system over the system LAN is recommended.

SEE ALSO: SE (SEssion)

top

Connection
CSP : Connect to remote Service Processor over the LAN

This command allows the local or remote/modem user to connect over the GSP LAN to another GSP on the network. The user that launches the command is given a private connection to the other GSP over the LAN. To return to the original GSP, type "CTRL-]" to disconnect the CSP session.

Other mirrored GSP users are placed in console mode when this command is executed. The CSP user returns to the mirrored GSP session after ending the CSP session.

SEE ALSO: LC, SE (LAN Configuration, SEssion)

Manufacturing
CT : Configure Tracing into GSP firmware

This command is only available in Manufacturing Mode.

More detailed help is not available for this command.

top

General Configuration
DC : Default Configuration- reset individual or multiple parameters

This command sets various GSP parameters back to their default values.

The user may reset all or a subset of the following parameters: IP configuration, modem configuration, paging configuration, command interface configuration, disable remote access, security configuration, session configuration. For example: setting the security configuration to default will erase all users and passwords.

(ADMINISTRATOR level command.)
SEE ALSO:
CA, EL, ER, IT, LC, PG, SO (Configure Asynchronous, Enable LAN, Enable Remote, Inactivity Timeouts, LAN Configuration, PaGing, Security Options)

Connection
DI : DIsconnect remote/modem or LAN/WEB console

This command disconnects the remote/modem or LAN/WEB users from the GSP. It does not disable the ports. To disable the ports, see the ER command for remote/modem and the EL command for LAN/WEB access. The TE and WHO commands are useful to identify the connected users before running this command.

SEE ALSO: ER, EL, TE, WHO (Enable Remote/modem, Enable LAN, TEll, Who)

DL COMMAND NOT SUPPORTED

For Display Logs, use the SL (Show Logs) command.

For Disable LAN, use the EL (Enable/disable LAN) command.

SEE ALSO: SL, EL (Show Logs, Enable LAN)

top

GSP Help

DR COMMAND NOT SUPPORTED

Please use:

ER : Enable/disable Remote console serial port modem access

The DR command has been replaced by the ER command. The ER command offers a selection of configurations for the remote console serial port modem, including disabling the port.

SEE ALSO: ER (Enable Remote/modem)

top

Port Configuration
EL : Enable/disable LAN/WEB console access

The EL command is used to set access permissions for users logging into the GSP over the LAN. The GSP can be set to allow telnet access, web access or both. It does not affect the IP configuration or the ability of the CSP command to connect over the LAN. It also does not affect the ability of the GSP to perform upgrades over the LAN (XU).

SEE ALSO: LC, LS (LAN Configuration, LAN Status)

top

Port Configuration
ER : Enable/disable Remote console serial port modem access

The following modes are available for the remote/modem port:
  1. LOCKED-OUT -
    Lock out all dial-in access

  2. GSP -
    Exclusive GSP access

  3. SESSION -
    Modem controlled by OS; both dial-in and dial-out

Dial-in to the modem results in:

Dial-out (paging) by the OS is allowed under the mode: SESSION. (The OS must be properly configured to use the modem.)

Paging by the GSP can be done under all modes. (Make sure that paging is enabled in the PG command.) GSP pages will wait until the modem is idle.

Translation from older versions of the GSP:

To enable/disable LAN access, use the EL command.

SEE ALSO: CA, EL, MR, MS, PG (Configure Asynchronous, Enable LAN, Modem Reset, Modem Status, PaGing)

top

General Configuration
IT : Inactivity Timeout settings

SESSION INACTIVITY TIMEOUT : up to 1440 minutes - typically 60 minutes
This timeout prevents sessions to the system from being inadvertently left open. A session can be started by the SE command. An open session can prevent users from logging onto the GSP through a port and can also prevent system applications from initiating an outbound connection.

GSP INACTIVITY TIMEOUT: up to (24x60) minutes - typically 60 minutes
This timeout prevents a user from inadvertently keeping the GSP locked in a GSP Command Interface mode preventing other users from looking at the console output. The GSP Command Interface inactivity timeout may not be deactivated.

(ADMINISTRATOR level command.)
SEE ALSO:
ER, SE (Enable Remote/modem, SEssion)

top

Port Configuration
LC : LAN configuration (IP address, etc.)

This command modifies the LAN configuration.

The GSP Host Name set in this command is displayed at the GSP command interface prompt. Typically the DNS name for the LAN IP is entered. This field can be programmed to any useful name or phrase. For clarity, it is useful to enter: "GSPNAME-on-SYSTEM" as the GSP Host name, so both names show up in the prompt (limit 19 chars, no spaces allowed.) The web access port number is also set by this command.

(ADMINISTRATOR level command.)

SEE ALSO: MS (Modem Status)

top

Status
MS : Modem Status- show modem signals and status

The MS command displays the state of the modem lines connected to the remote/modem serial port. The display can be updated by hitting a Carriage Return <CR>. The current state of the status signals DCD, CTS, DSR, RI and the last state of the control signals DTR, RTS set by the firmware are displayed. The text under "modem state" is an interpretation of these signals.

Manufacturing
OT : OverTemperature control configuration

This command is only available in Manufacturing Mode.

More detailed help is not available for this command.

top

Server Control
PC : Remote Power Control - turn system power on and off

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.

SEE ALSO: PS (Power Status)

top

Port Configuration
PG : PaGing parameter setup

When a chassis code arrives in the GSP, the paging list is checked to see if any pagers are enabled for that alert level. If so, the GSP will send a page to those pagers. Part of the alpha-numeric pager message is the string configured in this command, describing the alert level that caused the page.

If the modem is in use by either a dial-in connection to the GSP, a dial-in session to the OS, or a dial-out by the OS, all pages will queue up and wait until the modem is idle. Also, the modem presence in the CA command must be configured for \"always connected\" for paging to be possible.

(ADMINISTRATOR level command.)

RS : Reset System through RST signal

Under normal operation, shut down the OS before issuing this command.

This command causes the system to be reset through the RST signal.

Execution of this command irrecoverably halts all system processing and I/O activity and restarts the computer system. The effect of this command is very similar to cycling the system power- the OS is not notified, no dump is taken on the way down, etc.

SEE ALSO: TC (Transfer Control)

General Configuration
SDM : Set Display Mode (hex or text)

PARAMETERS: hex, text

This command is used to set the default display mode for chassis codes. It will affect the Virtual Front Panel (plus alerts), and the log viewer.

SEE ALSO: SL, VFP (Show Logs, Virtual Front Panel)

top

Connection
SE : SEssion- log into the system on local or remote port

Only valid from the local or remote/modem port, SE allows the user to leave the GSP Command Interface and enter a system session. Other mirrored GSP users are placed in console mode. The session user returns to the mirrored GSP session on exit.

The GSP regularly checks the activity of the session and will close the connection with the system and return the port to mirroring if the timeout period has elapsed. The timeout period is set in the IT command.

On HP-UX, the SE command will work on the local and remote ports.

DEVICE FILES: The CA command settings must agree with the OS device settings for the session UARTS. HP-UX device files are:

BAUD RATE: If the system and the GSP Command Interface local or remote ports have been configured with different port speeds, the baud rate changes to the rate specified by the OS for the duration of the session.

On MPE/iX, the SE command will only work on the connection to the remote/modem port. The CA command settings must agree with the parameters configured on the DTS User Port screen in NMMGR. An ldev must also be correctly configured in Sysgen for the I/O path to the session port.

The MPE/iX I/O path to the session port is 0/0/4/1.1

SL : Show Logs- view the chassis codes in the log history

This command displays the contents of the chassis codes and events that have been stored in non-volatile memory.

  1. Incoming -
    All chassis codes as they come in except for activity updates codes from the OS.

  2. Activity -
    All chassis codes of level 1 or greater

  3. Error -
    All chassis codes of level 2 or greater

  4. Current Boot -
    All chassis codes between "start of boot" and "boot complete"

  5. Last Boot -
    The chassis codes from the previous boot
Reading the Error Log turns off the Attention LED. Accessing this buffer is the only way to turn off the attention LED when it is flashing and alerts have not been acknowledged at the alert display level.

SEE ALSO: AC, SDM, VFP (Alert Configuration, Set Display Mode, Virtual Front Panel)

General Configuration
SO : Security options & access control (users, passwords, etc.)

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.)
SEE ALSO:
CA, PG (Configure Asynchronous, PaGing)

Status
SS : System Status- display the status of the system processors

The SS command displays the status of the system processors and which processor is the monarch.

The GSP learns the system configuration through the chassis codes it receives from the system. Therefore, there will likely be a delay between any processor configuration change and what is displayed by this command. A more reliable way to get the processor configuration information is at the BCH prompt.

SEE ALSO: PS (Power Status)

Server Control
TC : System reset through INIT or TOC (Transfer of Control) signal

Under normal operation, shut down the OS before issuing this command.

This command causes the system to be reset through the INIT (or TOC) signal.

Execution of this command irrecoverably halts all system processing and I/O activity and restarts the computer system. It is different from the RS command in that the processors are signaled to dump state on the way down.

VFP : Virtual Front Panel display

When invoked, this command 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:

  1. LIVE MODE -
    Invoked from the VFP command at the GSP prompt. To exit, you must type Q to quit to the console.

  2. EARLY BOOT MODE -
    When the boot sequence for the system begins, the live VFP is invoked automatically. When boot finishes, users are automatically switched to console mode.
The LED state reflects the state of the front panel LED's. When system power is off, the remote LED will show "OFF" even though remote access may be enabled in the EL or ER commands.
