AIX Commands

Found some AIX commands thru google. Thought to share here. Enjoy :)
1. Useful commands
Note All AIX commands reference can be found under
http //www.austin.ibm.com/doc_link/en_US/a_doc_lib/aixgen/wbinfnav/CmdsRefTop.htm
1.1 Memory
bootinfo –r shows how much RAM does my machine has (as root)
lsattr –E –l sys0 –a realmem shows how much RAM does my machine have (as non root)
rmss -c 512
rmss -r sets the memory size to 512 MB
resets the memory size to the original one
1.2 Devices



lsattr -El en0 displays en0 driver params
lsattr -El ent0 displays ent0 HW params
lsattr -El rmt0 displays tape params
lscfg -vp -l rmt0 (all information about a tape drive)
lsattr -El sys0 displays system type, firmware, etc driver params
lscfg –v lists all system HW config (NVRAM)
lsdev –Csscsi list all scsi devices
lsdev –Cspci list all pci devices
lsparent –Ck scsi list all scsi adapters
lsdevfc list fiberchannel devices
cfgmgr Configures devices
lsdev -Ccdisk Shows all disks
lsdev -Cctape Shows all tapes
cfgmgr -v -l device –v Specifies verbose output. The cfgmgr command writes information about what it is doing to standard output.
cfgmgr -v -l device Name Specifies the named device to configure along with its children.
If you only turned on a disk tower at e.g. scsi2 cfgmgr -v -l scsi2 will only configure this with detailed output.
lsdisp To check which graphic adapter is installed.
lscfg -vp -l mga0 (all information about a adapter)
lscfg -vp -l hdisk0 | grep Machine gives info about the disk manufacture type
lsslot -c pci For 6F1 only !!!! Lists all slots ,voltage,boards,etc !!!!
bootlist -m normal cd0 rmt0 hdisk0 Changes the default bootlist
lsmcode -c display the system firmware level and service processor
lsmcode -r -d scraid0 display the adapter microcode levels for a RAID adapter scraid0
lsmcode -A display the microcode level for all supported devices





1.3 System info

/usr/bin/uname -m Get machine ID
/usr/bin/uname -M Get platform type
oslevel Displays current AIX level
oslevel -r Displays current AIX maintenance level
oslevel -g List filesets at levels later than maintenance level !!!
lsps -a Paging space settings.
lscfg -vp -l proc0 (1,2,3) (all information about a processor[s])
lscfg -vp -l mem0 |pg (all information about memory modules installed)
env ulimit Environment setings - show user ulimit
bootinfo –s hdisk0 Displays disk size
lsattr -El sys0 -a systemid Determines the system serial number
lscfg –vp|grep ROM|grep -v CD Determines the system Firmware level
1.4 System issues

TERM=vt100 -If you execute a command/application and it responds with msg
‘ The type of your terminal is unknown to the system’,run those commands (In ‘ksh’)
set term=vt100 -Same (In tcsh’)
rcp -rp /dataVolumes/brisque1.1.0/jobs/flower.job sciroot@ripro3:/dataVolumes/ripro3.3.0/jobs/ -Copying a file from one Unix machine (Brisque) to another (Server) the assumption is that both machines know each other’s names (in hosts file)
dd if=/dev/fd0 of=/temp/diskimage bs=4096 -Duplicate a diskette copy from diskette to hard drive
dd if=/temp/diskimage of=/dev/fd0 bs=4096 -copy diskette image onto diskette
/usr/lpp/X11/bin/xset -display unix 0 s off -Kill display timeout
lsfs -v jfs -List of Filesystem items.
lsfs -q -v jfs -you can see also the parameter of a filesystem and thus see if e.g. /backup was or is a big_filesystem_enabled one.
Important for the 2GB File limit.
lsuser –f root Shows all user parameters (max .file size,etc)
sysdumpdev -L Check last system dump status
sysdumpdev -l Check system dump device settings
lslpp -f Upd_Timna_DTM.obj List contents of the package
