Hey, take a look at the ugly AIX image that I just stole. Since I ran into the image thought that I would take a bit of time to get my AIX notes together and put my new image to good use.
Here are some of my favorite commands and other info.

Memory and Paging
lsattr -E -l sys0 | grep realmem
To determine how much physical memory resides on the hardware, use the
AIX following command to determine the amount of physical memory:
To determine how much paging space is
installed; use the command above.
To increase Paging Space; use the following AIX path in SMIT (System
Management Interface Tool)
Physical and Logical Storage -> Paging Space -> Change/Show
Characteristics of Paging Space
Do not add a new paging logical volume. Add specified PP’s (as needed)
to the existing paging logical volume. Select logical volume and press
return. Type 1 for the Number of additional logical partitions.
netstat -v | grep Speed
Show NIC speed
Collect System Dump on an AIX System
- Verify dump size by typing sysdumpdev –L at the command line.
- Find a repository large enough for the dump.
- Type snap –r at the command line to remove any previous dumps.
- Type snap -gfkDGL at the command line to create the new dump.
- Type snap –c to compress into the pax file.
Intro to SMIT/SMITTY
- System Management Interface Tool
- smit will run GUI version if $DISPLAY is set, text version otherwise
- Use smitty to force use of text version
- Important keystrokes (If you don’t have function keys, use ESC+n for Fn):
F3 > Cancel (go back to previous screen)
F4 > List options for a given field
F6 > Show command that SMIT is executing
F7 > Tag item from list (e.g., when selecting software to install)
F10 > Exit SMIT
smit.log >Logs what you’ve done (menu selections, command output, etc)
smit.script > listing of all commands SMIT has executed for you (same as shown by F6)
Command prefix naming conventions:
o ch (change)
o ls (list)
o mk or cr (make or create)
o rm (remove)
