  • Page 15: Sun Remote System Control (Rsc) Software

    The RSC software works with the System Service Processor (SSP) on the Sun™ Enterprise™ 250 main logic board. RSC and the SSP support both serial and Ethernet connections to a remote console.
  • Page 16 RSC Remote Access Paths FIGURE 1-1 Once RSC software is installed and configured to manage your server, you can use it to run diagnostic tests, view diagnostic and error messages, reboot your server, and display environmental status information from a remote console.

  • Page 17: Rsc Features

    RSC also sends alerts to any clients that are currently logged in to RSC. RSC sends an alert message whenever any of the following occurs:...
  • Page 18 A server redundant power supply fails. A power outage occurs at the server site, if an uninterruptible power supply (UPS) is in use and it is configured to send an alert to RSC (see Appendix A). RSC receives a server-generated alert.
  • Page 19 Secure serial bus Secure Ethernet ASCII terminal ASCII terminal and modem and modem Company modem RSC modem pool Solaris workstation Windows PC RSC Remote Alert Paths FIGURE 1-2 Chapter 1 Sun Remote System Control (RSC) Software...

  • Page 20: Rsc Capabilities

    After receiving an alert message, you can connect to your RSC account for the server that caused the alert. Then you can check console messages to determine whether the server has recovered and is running, or whether the server operating system is down.

  • Page 21: View Logs

    After installation, you run a script file that guides you through basic configuration. See the Sun Remote System Control (RSC) Installation Guide. If you want to be able to use RSC in case of a complete power failure, you should install and configure an uninterruptible power supply (UPS) for the server. See Appendix A.

  • Page 22: Rsc Security

    You can set RSC to disconnect a session connected to the serial port after ten minutes of inactivity;...

  • Page 23: Installing And Configuring Rsc Software

    After operating system software is installed on the server to be managed, you can install RSC software on the server. Note – After RSC software is installed on the host, it resides in the directory /usr/platform/sun4u. Until RSC host software is installed and configured, the system console is available as on any normal Sun computer.

  • Page 24: Configuring Rsc Software

    After initial configuration, you can control configuration and add or modify user accounts by using the GUI or RSC shell commands. You can also log in to the host as root and use the rscadm utility to control RSC configuration and user accounts; see Chapter 5.

  • Page 25: Configuring Ppp

    If point-to-point protocol (PPP) is enabled on the serial port, RSC supports multiple sessions, either shell or GUI, through one modem connection. If PPP is not enabled, only one session can be run over the modem, and it must be a shell session. RSC supports multiple sessions over its Ethernet port.

  • Page 26: Configuring Alerts

    The GUI provides help for configuring RSC alerts. For help configuring RSC alert variables in the shell, see “Alert Variables” on page 38. RSC generates alert messages with the following format: $HOSTID $EVENT $TIME $CUSTOMERINFO $HOSTNAME message You can also use the rscadm subcommand send_event -c to send an alert. You can do this directly at the superuser prompt, and you can also create a command file that runs and sends the alert under special circumstances.

  • Page 27: Backing Up Rsc Configuration

    Use a meaningful file name that includes the name of the server that RSC controls. Later, you can refer to this file to restore the settings if you need to reinstall RSC software on the server or replace the server’s main logic board.
  • Page 28 Sun Remote System Control (RSC) User’s Guide • March 1999...

  • Page 29: Using The Rsc Graphical Interface

    (GUI). This chapter gives an overview of how to access the RSC GUI, and use of RSC windows and dialog boxes. If you need to use RSC commands and the GUI is not available, you can use RSC shell commands. After you log in to your RSC account from a terminal window, the RSC shell prompt appears (rsc>), and you can enter commands.

  • Page 30: Accessing Rsc Functions

    Note – It is important that you enter the name or IP address of the RSC device, not the name or IP address of the server. To monitor or control more than one server, start a separate GUI session for each.

  • Page 31: Rsc Permissions Required For Access To Gui Functions

    RSC Permissions Required for Access to GUI Functions All RSC users can look at RSC information. The table in the RSC User Administration dialog box shows additional permissions assigned to each user. These additional user permissions grant access to specific items in the GUI command tree.

  • Page 33: Using The Rsc Command Shell

    (GUI). Online Help is available when you use the GUI. If you need to use RSC and the GUI is not available, you can use the RSC command shell. The RSC command shell is a simple command-line interface that supports commands that allow you to administer or diagnose the server.

  • Page 34: Logging In To Your Rsc Account

    After RSC software is installed and configured and an account has been set up for you, you can connect to RSC and log in to your account using a Solaris workstation, Windows PC, standard ASCII character terminal, or a computer running ASCII terminal emulation software.
  • Page 35 You can enter RSC shell commands at the rsc> prompt. Logins are recorded in the RSC event log. In addition, RSC sends an alert if it detects five login failures within five minutes. You can also set RSC to disconnect a session connected to the serial port after ten minutes of inactivity;...

  • Page 38: Shownetwork

    You must have C level user permission to use this command. An escape character sequence is used to return to the RSC prompt. The default escape sequence is ~. (tilde period). See “escape_char” on page 43. break Use the break command to put the server into debug mode.

  • Page 39: Bootmode [-U] [Normal|Forth|Reset_Nvram|Diag| Skip_Diag]

    If you use the bootmode command without arguments, RSC displays the current boot_mode. The bootmode setting overrides the server’s OBDiag diag-switch? setting immediately after the next reset only. If RSC does not detect a server reset within 10 minutes, the bootmode command is ignored. For example: rsc> bootmode forth rsc>...

  • Page 40: Reset

    Use the poweroff command to power off the server. You must have R level user permission to use this command. This command has no effect if the server is already powered off. RSC remains available since it uses the server’s standby power. poweron Use the poweron command to power on the server.

  • Page 41: Rsc View Log Commands

    Use the loghistory command without subcommands to display the history of all events logged in the RSC event buffer. These events include server reset events and all RSC commands that change the state of the system. You can also use the command abbreviation lhist.

  • Page 42: Pause N

    16 Kbytes of information. When the first power-on boot begins, RSC fills the original boot (oboot) buffer with data from the server’s console. After that buffer fills up, it writes data to the original run (orun) log.

  • Page 43: Pause N

    When RSC senses a server reset while in the orun log, it switches to the boot log. After that fills up, it switches to the run log. When the run log fills up, it overwrites old data in the run log.

  • Page 44: Set Variable Value

    See “RSC Configuration Variables” on page 35 for descriptions of these variables. Changes to some variables do not take effect until the SSP that RSC is running on is reset using the command resetrsc or rscadm resetrsc.

  • Page 45: Date [[Mmdd]Hhmm|Mmddhhmm[Cc]Yy][.Ss]

    9:45 p.m. of the current month, day, and year. Note – Whenever the server boots, it sets the RSC current date and time. However, to keep RSC time in sync with server time, Sun Microsystems recommends that you implement a script that uses the command rscadm date -s to update RSC time periodically from the server time.

  • Page 46: Password

    When used to change a password, RSC prompts for your current password, and if you enter it correctly, it prompts for the new password. RSC prompts again for the new password, and updates it if entered identically both times. For example: rsc>...
