The GSP has several features that must be configured in order for them the be available. The following sections give a description of each feature and the command used to configure that feature. See the online help for details about the options that are available. The GSP configurations require you to enter commands in a dialog format. Pay close attention to the prompts. You may be asked for confirmation before each parameter takes effect.

Operator / Administrator summary

Administrators have more capabilities than Operators:

Administrator-Only Commands: AR (Automatic server Restart), DC (Default Configuration), IT (Inactivity Timeout), LC (LAN Configuration), PG (PaGing), SO (Security Options)
The GSP Command interface permission/access level: The 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 in operator mode. Even if an administrator-user logs in later or if the operator-user disconnects, the mode stays the same. The mode will only change when the GSP command interface is left (to go to COnsole, for instance), and CTRL-B is typed again to return.

If no users are configured then all connections to the GSP have administrator capability. The first user configured will have adminstrator capability, when you configure additional users, you have the choice to give the user administrator or operator capability.

If you forget the administrator user or password you must reset the users configuration via a small reset button on Core I/O card at back of the system to regain access to the GSP. After the GSP finishes its reset, you will see a prompt and have the opportunity to reset the user configuration. If you don't answer the prompt before it times out, the user configuration will be retained.

Console and remote port configuration (CA, ER)

The following text shows the parameters that should be configured for the Local and remote serial ports. These parameters assume that the remote console port will be used for remote support and that it will be connected to the support modem.


  GSP Host Name:  <name>
  GSP> ca
  
  CA
  
  This command allows you to modify the local and remote modem serial port
  configurations. Current configuration settings:

    Local Console Serial Port bit rate: 9600 bits/s
    Local Console Serial Port Flow Control: Software
    Local Console Serial Port Terminal Type: hpterm
    Remote Console Serial Port Modem Protocol: Bell
    Remote Console Serial Port Modem bit rate: 9600 bits/s
    Remote Console Serial Port Modem Flow Control: Software
    Remote Console Serial Port Modem Transmit Configuration Strings: Enabled
    Remote Console Serial Port Modem Presence: always connected

  GSP Host Name:  <name>
  GSP>

The ER Command is used to enable or disable remote serial port modem access. The following modes are available for the remote/modem port:

LOCKED-OUT — Prevent any dial-in access
GSP — the user will login to the GSP command interface when a connection is established.
SESSION — The user will connect to the ldev configured on the remote port I/O path.

If the port access is set to GSP, then you can use the GSP>SE command to establish a session to the ldev configured on the remote port I/O path. The Remote Serial Port Modem Protocol parameters that are set with the CA commanad must match the parameters for the User Port in NMMGR. The parameters that must match are:


  Baud rate       - The baud rate must be the same
  Modem protocol - Bell protocal in the GSP equals Modem Type 1 (US),
                   and CCITT protocol equals Modem Type 2 (European.
            Parity                - The parity must be the same.

See steps 1 through 4 in the section 'Configuring the Remote port for Predictive Support' for instruction on how to configure the Remote port parameters to match.

Configuring the Remote Port for Predictive Support

This section contains the guidelines for configuring the remote modem on A-Class and N-Class servers. In most environments, the remote port is used solely to provide a remote connection for Predictive Support. These instructions are tailored for using Predictive Support on the remote port. The supported modem is the Multi-Tech MT5634ZBA (HP Part Number: 0960-1074).

Initiate a new session on any terminal and log on as MANAGER.SYS.
Run Sysgen and enter the IO command. Make sure that ldev 21 is configured as follows (same for both the A-Class and N-Class):
```
  io> ld 21
   LDEV:    21  DEVNAME:          OUTDEV:    20  MODE:  JAID
     ID: C1099A                   RSIZE:     40  DEVTYPE: TERM
   PATH: 0/0/4/0.1                MPETYPE:   16  MPESUBTYPE:  0
  CLASS: TERM
```
NOTE: The configuration for the Hp e3000 PA-8700 N-Class and A-Class servers uses the hardware path of 0/0/4/1.1

Run NMMGR. Press the following function keys: F1 [Open Config], F1 [DTS], F4 [Go to UserPort]. Verify the settings are as follows (same for both theA-Class and N-Class):


  Logical Device [21 ]
  Line Speed     [9600]
  Modem Type     [1]
  Parity         [NONE]

Make sure the the upper right corner of the screen is 'Data:Y'. Press F6 [Save Data] if it is not. Validate DTS subsystem in NMMGR and exit.

NOTE: A different line speed could be used, but by default Predictive will set the speed to 9600 when it has finished a call. See the Predictive configuration information if you want to set a higher speed. The maximum speed supported is 19200 due to a hardware driver limitation.

Access the GSP via the system console or GSP LAN access. At the GSP prompt enter the CA command. Make sure the Remote Console Serial Port parameters are set as described in the above section 'Console and Remote Port Configuration (CA,ER)'.
If you are installing a new support modem then leave the modem configured with the factory default settings. If you are not sure the modem is set to the factory defaults connect the modem to a terminal and set the modem to the factory defaults with the following commands:
```
  AT&F&WATZ
```
Connect the modem to the remote serial port. Issue the GSP> MS command to reset the modem and cause the GSP to send the necessary configuration commands to the modem.
Configure the remote modem port access using GSP>ER command to the SESSION option:
Schedule a system shutdown and restart the system with norecovery option to have the changes take effect.

GSP LAN configuration (LC)

This commnd modifies the GSP LAN/Console configuration.These parameters must be set to allow access to the GSP via the GSP LAN/Console port. This command sets the following:

The IP address
The host name displayed at the GSP prompts
The Subnet mask to be used by this node
The address of the gateway node for this network

Display a list of GSP connected users (WHO)

This command displays the login name of the connected console client users and the port on which they are connected. For the LAN console clients the remote IP address is also displayed.

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.

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:

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

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.
