UNIX system administration challenges Lots of commands to remember Complex syntax

Prone to error! Flat file configuration

Most UNIX flat files have different layouts, syntax, and options. Again prone to error, sometimes causing bad things to happen.

# crfs -v jfs -g rootvg -m /test -a size=42M efs=yes

Usage: crfs -v Vfs {-g Volumegroup | -d Device} -m Mountpoint [-u Mountgroup] [-A {yes|no}] [-t {yes|no}] [-p {ro|rw}] [-l Logpartitions] [-n nodename] [-a Attribute=Value]

How do I create an encrypted file system?

SMIT An interactive application that simplifies virtually every aspect

of AIX system administration. Part of AIX, SMIT is available by default. SMIT does not use any special hooks. Everything is based on

standard AIX commands and Korn shell functions. You can see exactly what commands it performs either before or after

execution. This is especially useful when you need to automate a repetitive task.

You can then use these commands in your own scripts.

Text / ASCII based by default. If on a graphical display, such as the Virtual Network Computing (VNC)

viewer, and the DISPLAY variable is set, a Motif GUI version is displayed.

Most users prefer the text based version called smitty.

IBM Systems Director Console for AIX (pconsole) Web-based management interface (starting with AIX 6.1) Enables converged consoles consistent with IBM Systems

Director: Integrated solutions console Lightweight infrastructure

Includes links to SMIT tasks Requires Java v5 Installed by default

OS Management (new SMIT-based tasks) Portlets/modules

For example, system health

Classical SMIT Classic-style smit menus for those who prefer a more traditional look

and feel

Distributed Command Execution Manager (DCEM) Used to execute commands on multiple systems in parallel Based on the standard UNIX dsh function

On AIX, this is part of the Cluster Systems Management (CSM) product, csm.dsh, which is installed as part of a base AIX install.

Supports groups of systems Supports rsh and ssh authentication
