Some notes and tips on maintaining AIX systems
 
 
Shutdown
To restart the machine,
shutdown -Fr
 
 
SMS utilities console
To access the SMS utilities console, press 1 or F1 when the keyboard is being recognized.
Note press Shift+1 on azerty keyboards (french one here).
 
 
Checks
Make sure the postinstall wizard is deactivated. It may still be in /etc/inittab,
vi /etc/inittab
 
Check maintenance/technology level,
oslevel -s
instfix -i | grep ML
 
Check for disk mirroring (software raid),
lspv
lsvg -l rootvg
Note. PPs should be twice the amount of LPs
 
Check on what device the system boots up,
bootlist -o -m normal
Note. for example, cd0, rmt0, hdisk0, hdisk1
 
Sometimes if the bootlv is outside the first 4gb of disk this can happen. It's worth to try the following. Boot into maintenance mode, mount the filesystems, type the following and reboot,
rmlv hd5
mklv -t boot -y hd5 -a e rootvg 1 hdisk0
bosboot -ad /dev/hdisk0
shutdown -Fr

Check for Hardware errors,
errpt lft0
errpt > errpt.list
errpt -a > errpta.list
Note the dates, latest is at top, if I remember correctly.
 
 
Packages
Check packages' consistency,
lppchk -v
Note if you get errors, do some digging e.g., THAT's JUST HINTS & EXAMPLES,
lslpp -L all | grep cpio
lslpp -lc
lslpp -l "*cpio*"
lslpp -hc | grep cpio
lppchk -vm3
installp -pv dvices.common.cpio.rte
It may be an ODM inconsistency which may be fixed e.g., THAT's JUST HINTS & EXAMPLES,
echo $ODMDIR
(cd /etc/obm/)
(cd /usr/lab/objx/)
(cd /etc/objrepos/)
obmget product
obmget lpp
odmget -q lpp-name="devices.common" product
odmdelete -o product -q lpp-name="nom entrée"
(obmdelete -o product -q lppname "nom entrée")
obmdelete -o product -q "nom entrée"
 
Proceed with some updates doing,
smit update_all
Note. if new packages are working fine, validate them (and prevent going backwards) using smit.
 
 
Update
To perform an update, get the fixes from http://www.ibm.com/ and,
lppchk -v
errpt -a
smitty update_all
#shutdown -Fr

Security
Try this command,
aixpert
and check into security/aixpert,
ls -l /etc/security/aixpert
