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]

SMIT• An interactive application that simplifies virtually every aspect of AIX
system administration
• Part of AIX, available by default
• SMIT doesn't 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

Web-Based System Manager• A Java based GUI, similar to SMIT in functionality
• Part of AIX (available by default), based on a client/server model
• Resource intensive and more cumbersome to use than SMIT
• For AIX6, users should consider using IBM Systems Director Console for AIX

IBM Systems Director Console for AIX• New web based management interface in AIX 6.1• Enables converged consoles
– Integrated solutions console– Lightweight infrastructure
• Includes links to SMIT and WebSM tasks• Requires Java v5 • Installed by default
– sysmgt.pconsole.rte– sysmgt.pconsole.apps.wdcem– sysmgt.pconsole.apps.websm– sysmgt.pconsole.apps.wrbac– sysmgt.pconsole.apps.wsmit– lwi.runtime
