This section describes how to login to the service processor (MP or GSP) for a server complex.

You can connect to the service processor for a server complex by using the following methods:

  • Connecting through the customer LAN port by using telnet, if login access through the customer LAN is enabled for the service processor.

    On HP Superdome servers, the customer LAN hardware is labeled "Customer LAN". On HP rp8400 servers it is "GSP LAN". On HP rp7405/rp7410 servers it is the only LAN port on the core I/O.

    Use telnet to open a connection with the service processor, then login by entering the account name and corresponding password.

  • Connecting through the local RS-232 port using a direct serial cable connection.

    On HP Superdome server hardware, the local RS-232 port is labeled "Local RS-232". On HP rp8400 servers it is the "Local Console" port. On HP rp7405/rp7410 servers it is the 9-pin D-shaped connector (DB9) labeled "Console".

  • Connecting through the remote RS-232 port using external modem (dial-up) access, if remote modem access is configured.

    On HP Superdome server hardware, the remote RS-232 port is labeled "Remote RS-232". On HP rp8400 servers it is the "Remote Console" port. On HP rp7405/rp7410 servers it is the DB9 connector labeled "Remote".

Example 4-1 Overview of a Service Processor Login Session

The following output shows a sample login session for a server whose service processor hostname is "hpsys-s".

Procedure 4-1 Logging in to a Service Processor

This procedure connects to and logs in to the service processor (MP or GSP) for a server complex by using telnet to access the customer LAN.

If connecting through the local RS-232 port, skip Step 1 (instead establish a direct-cable connection) and begin with Step 2.

  1. Use the telnet command on a remote system to connect to the service processor for the server complex.

    You can connect directly from the command line, for example:

    telnet sdome-g

    or run telnet first, and then issue the open command (for example, open sdome-g) at the telnet> prompt.

    All telnet commands and escape options are supported while you are connected to the service processor.

  2. Login using your service processor user account name and password.

    GSP login:Username
    GSP password:Password
  3. Use the service processor menus and commands as needed and log out when done.

    To log out, select the Exit Connection menu item from the Main menu (enter X at the GSP> prompt or MP> prompt).

    You also can terminate a login session by issuing the telnet escape key sequence ^] (type: Control-right bracket) and entering close at the telnet> prompt.

    NOTE: If possible, you should log out of any consoles and menus before terminating your telnet session.

    If accessing an OS on an nPartition, log out of the OS before exiting the console and service processor sessions. (Otherwise an open OS login session will remain available to any other service processor users.)

Using Service Processor Menus

The service processor (MP or GSP) has a set of menus that give you access to various commands, consoles, log files, and other features.

See “Navigating through Service Processor Menus” for details on using these menus.

The following menus are available from the service processor Main menu (which is the menu you first access when logging in):

  • Console Menu—Provides access to nPartition consoles for the server.

  • Virtual Front Panel Menu—Provides a Virtual Front Panel for each nPartition (or for the entire server complex).

  • Command Menu—Includes service, status, system access, and other commands.

  • Console Log Viewer Menu—Allows access to the console logs for nPartitions.

  • Chassis Log Viewer Menu or Event Log Viewer Menu—Allows access to the server chassis code logs (on HP 9000 servers with HP PA-8700 processors) or event logs (on servers based on the HP sx1000 chipset or HP sx2000 chipset). Chassis logs and event logs are functionally equivalent: they record system activities. However, event logs are more descriptive.

  • Help Menu—Provides online help on a variety of service processor topics and on all service processor Command menu commands.

These menus provide a central point for managing a server complex outside of an operating system.

The service processor menus provide many tools and details not available elsewhere. More administration features also are available from the nPartition system boot environments (BCH or EFI), the nPartition tools, and various operating system commands.

Navigating through Service Processor Menus

The following list includes tips for navigating through service processor menus and using various menu features:

  • Control-b

    Exit current console, console log, chassis log, or Virtual Front Panel.

    When accessing the Command menu, an nPartition console, any log files, or any Virtual Front Panel (VFP), you can exit and return to the Main menu by typing ^b (Control-b).

  • Q (or lower-case q)

    Exit or cancel current menu prompt.

    Enter Q (or lower-case q) as response to any menu prompt to exit the prompt and return to the previous sub-menu.

    You can do this throughout the service processor menus, including the console menus, various command menu prompts, and the log and VFP menus.

    Note that, from the Command menu prompt (GSP:CM> or MP:CM>) you must enter MA (not Q) to return to the Main menu. However, you can enter Q or q to cancel any command.

  • Control-]

    Escape the service processor connection and return to the telnet prompt.

    At any time during your telnet connection to a service processor, you can type the ^] (Control-right bracket) escape sequence.

    This key sequence escapes back to the telnet prompt. When at the telnet> prompt you can use the following commands, among others: ? (print telnet command help information), close (close the current connection), and quit (exit telnet).

    To return to the service processor connection, type enter (or return) one or more times.

Network Configuration for a Service Processor

This gives an overview of the network settings for service processor (MP or GSP) hardware. These settings are used for connections to the service processor and are not used for HP-UX networking.

Details on configuring service processor networking are given in the service guide for each server.

The service processor utility hardware on HP Superdome servers has two network connections: the customer LAN and private LAN.

The service processor on other (non-Superdome) cell-based servers does not have a private LAN; only a customer LAN connection is provided.

Features of service processor LANs are given in the following list.

  • Customer LAN for Service Processor. The customer LAN is the connection for login access to the service processor menus, consoles, commands, and other features.

    All cell-based servers have a customer LAN.

    On HP Superdome servers, the customer LAN port is labeled "Customer LAN". On HP rp8400 servers it is "GSP LAN". On HP rp7405/rp7410 servers it is the only LAN connection on each board.

  • Private LAN for Service Processor (Superdome Only). The private LAN is the connection to the Superdome service support processor (SSP) workstation, also called the service management station (SMS).

    Only Superdome servers have a private LAN. It typically is not used on the Superdome server models based on the HP sx1000 chipset or HP sx2000 chipset.

To list the current service processor network configuration, use the LS command. To configure service processor network settings, use the LC command from the Command menu. For a procedures, refer to the service guide for your server.
