How to check the oslevel of the altaltinst_rootvg in aix?
Sometimes we will be in the situation to identify the oslevel / TL / SP of the altinst_rootvg to proceed further for our activity (next task), Using the below steps we can easily identify the os version of the altinst_rootvg in aix
Test2:/# oslevel -s
7100-01-04-1141
Test2:/#
Test2:/# lspv
hdisk0 00d342e7131c6b47 rootvg active
hdisk1 00d342d637j21a59 altinst_rootvg
Test2:/#
Test2:/# alt_rootvg_op -W -d hdisk1
Waking up altinst_rootvg volume group ...
Test2:/#
Now the altinst_rootvg is in Active state also alt filesystems are in mounted state on the server
Test2:/# lspv
hdisk0 00d342e7131c6b47 rootvg active
hdisk1 00d342d637j21a59 altinst_rootvg active
Test2:/#
Test2:/# df

We need to start the chroot shell within the alternate rootvg to identify the OS level/TL/SP information.
Test2:/# chroot /alt_inst /usr/bin/ksh
Test2:/# oslevel -s
7100-01-01-1216
Test2:/#
Test2:/# exit
you can return to the rootvg environment by exit from the alt shell.
Now it is really really important to put the cloned rootvg back to sleep.
Test2:/# alt_rootvg_op -S altinst_rootvg
Putting volume group altinst_rootvg to sleep ...
forced unmount of /alt_inst/var
forced unmount of /alt_inst/usr
forced unmount of /alt_inst/tmp
forced unmount of /alt_inst/opt
forced unmount of /alt_inst/home
forced unmount of /alt_inst
Fixing LV control blocks...
Fixing file system superblocks...
The bootlist command confirms that you will reboot using the alternate rootvg disk (hdisk1).
Test2:/# bootlist -m normal -o
hdisk1 blv=hd5 pathid=0
hdisk1 blv=hd5 pathid=1
Test2:/# lspv
hdisk0 00d342e7131c6b47 rootvg active
hdisk1 00d342d637j21a59 altinst_rootvg
Test2:/#
you can use the same steps to get the os level information from old_rootvg as well.
