HP-UX System Administration Documentation

This document outlines some additional items that differ from administering Tru64 Unix

System Administration Utility

The system administration GUI on HP UX is called "sam", and is invoked by typing "sam" at the prompt.

Booting the computer

When booting the computer, it will stop at a prompt that says "WARNING: YOU ARE SUPERUSER". You must enable multi-user mode to allow users to login. Type "init 6" at the # prompt.

Hard disk configuration

Cricket has two hard disks that are independently partitioned. There is no file domain with filesets from both disks. This is done to prevent complete loss of data in the event of a crash.

The first disk consists of the operating system, software and scratch directories. Software should be installed in "/home/software". Abaqus scratch should be written to "/home/scratch". Sometimes, software comes pre-compiled, and will be automatically installed in "/opt".

The second disk consists of user directories, all of which are in "/home2/username". Also, to maintain consistency with our group's convention, "/home2" is linked virtually to "/usr/home/cricket" so that each user's directory is also "/usr/home/cricket/username".

Creating new users

Log on as root and use the Account Administration tool in Sam. Ensure the following entries are correct:

• username
• user ID: get from athena by typing 'id' at the athena prompt
• home directory: "/home2/$USER"
• shell: "tcsh" or "/opt/tcsh/bin/tcsh"
• password

Software installation

Currently, HP-UX 11 is installed on Cricket. Additional software can be obtained from:

http://software.hp.com
http://hpux.cs.utah.edu

Software comes either as "gzipped source" (which you have to download and compile), or as "dynamically linked binary" (which is pre-compiled, and you can install with the help of HP's swinstall gui).

The downloaded file is a compressed archive with a "tar.gz" file extension. Move the archive to "/home/software" and type "gunzip filename.tar.gz" then "tar xvf filename.tar". This uncompresses the installation files into a directory with the same name as the archived file. If it is an uncompiled source, you will enter that directory and follow the directions in the "README" file to continue installation. Alternatively, if it is a pre-compiled software "depot", you will install it using the SWinstall utility in Sam.

When finished, create a link to the programs executable in the "/usr/bin" directory by typing "ln -fs /executable_path/executable_name /usr/bin/executable_name"
