AIX TL/ML Migration/Upgradation with MultiBOS method
AIX ML/TL Migration/Upgradation can be done in many ways. I am here sharing the method, which worked for me.
Current TL/ML Level
Current TL/ML Level
- # oslevel –s >>> Show current AIX Fix Level
- # lppchk –v >>> Show installed packages
- # instfix -i | grep ML >>> Show the currently installed ML
- # lslpp -l | grep -i applied >>> Check for any applied level packages
- # installp -c -f -g –X >>> Commit all the applied level packages
Creating
MultiBOS instance
- # multibos -sXp >>> Pretend MultiBOS creation(Mock Run)
- # multibos -sX >>> MultiBOS instance creation
Install
the TL/ML updation from location
- # mount nimmaster:/export/5300-12-00-1015 /shared >>> Mount the TL files source
- # multibos -Xacp -l /shared >>> Pretend TL/ML migration on Standby BOS(Mock Run)
- # multibos -Xac -l /shared >>> TL/ML migration on Standby BOS
Confirming
the Update Success
- # multibos –S >>> Login to Standby BOS environment
- # oslevel –s >>> Check whether migration succeeded
- # lppchk –v >>> Check the lpp health after migration
- # instfix -i | grep ML >>> Show the currently installed ML
- # oslevel –rl 5300-12 >>> Incase of problem to know the missing pkg
- # multibos -Xc -b /tmp/listofpkgs -l /shared >>> Install missing, if req
Checking
the BootLV Change
- # bootlist -m normal –o
Reboot
the Server and check the Applications is running properly
- # shutdown –Fr
Fallback (Point the BLV to the original LV -- hd5)
- # bootlist -m normal –o hdisk0 blv=hd5 hdisk0 blv=bos_hd5
Log
