    Chapter 4 Remote Management This chapter contains an overview of the remote control features and describes how remote management is supported. Overview An AlphaServer DS20L system is usually configured in a network cluster with other rack-optimized nodes. Each system has integrated network interfaces so that management stations can be used for control rather than duplicating central management functions on each system.

    Appendix A SRM Console The SRM console is the command-line interface that supports the Tru64 UNIX and Linux operating systems. The SRM console is used to bootstrap the operating system, configure and test the system hardware, examine system options for errors, and set or change environment variables.

If the checksum in the first sector is correct, SRM goes ahead and reads the size sectors starting from the sector given in the sector number field and places them in virtual memory at address 0x20000000.

A.9.1 Set Password The set password command sets the console password for the first time or changes an existing password. It is necessary to set the password only if the system is going to operate in secure mode.

  • Page 119: Set Secure

    A.9.2 Set Secure The set secure command enables secure mode without requiring a restart of the console. If the password has been set, the console will be secured and only a small subset of commands can be performed. If a password has not been set, you are prompted to do so.

  • Page 120: Secure Mode

    A.10 Secure Mode When the console is in secure mode, the only commands recognized are boot, login, continue, and start. Placing the console in secure mode ensures that unauthorized persons cannot gain access to the system. The commands for console security are set password, clear password, and set secure.

  • Page 121: Clear Password

  • Page 124: Forcing A System Crash Dump

    NOTE: If the system has been shut down from a booted program (most commonly, the operating system) or in some other way halted back to the SRM console, the system must be reset before running LFU. See Chapter 3 for more information about LFU. A.14 Forcing a System Crash Dump The crash command forces a crash dump at the operating system level.

  • Page 125: Using Environment Variables

    A.15 Using Environment Variables Environment variables pass configuration information between the console and the operating system. Their settings determine how the system powers up, boots the operating system, and operates. You issue an init command to activate a new environment variable. Environment variables are set or changed with the set envar command (where envar is a placeholder for the environment to be changed) and set to default values with the set -default envar command.
