Bootlist is set to the boot disk: hdisk1

hdisk0 000a738834162dc4 old_rootvg
hdisk1 000a738829e828ce rootvg active
root@nimserver(/)#
Now upgrade the Oslevel from 5300-04 to 5300-12-05-1140
root@nimserver(/)# lspv
hdisk0 000a738834162dc4 old_rootvg
hdisk1 000a738829e828ce rootvg active
root@nimserver(/)#
I have already downloaded the technology level & service pack 5300-12-05-1140
root@nimserver(/backupnim/5300-12)# inutoc .
root@nimserver(/backupnim/5300-12)# smitty update_all
root@nimserver(/)# oslevel -s
5300-09-08-1036

root@nimserver(/backupnim/5300-12)# inutoc .
root@nimserver(/backupnim/5300-12)# smitty update_all
So technology level is upgraded to
root@nimserver(/backupnim/5300-12)# oslevel -s
5300-12-05-1140
root@nimserver(/backupnim/5300-12)#
root@nimserver(/)# lspv
hdisk0 000a738834162dc4 old_rootvg
hdisk1 000a738829e828ce rootvg active
root@nimserver(/)#
My current bootlist is
root@nimserver(/)# bootlist -m normal -o
hdisk1 blv=hd5
root@nimserver(/)#
Now some reason, I have to revert back the whole process and I wants to go back to my old oslevel/technology level (5300-04) which is still on hdisk0. Set the boolist back to hdisk0 and reboot the lpar.
root@nimserver(/)# bosboot -ad /dev/hdisk0
0301-168 bosboot: The current boot logical volume, /dev/hd5,
does not exist on /dev/hdisk0.

Remove the alternate rootvg
root@nimserver(/)# exportvg altinst_rootvg
root@nimserver(/)# lspv
hdisk0 000a738834162dc4 rootvg active

Use the following two commands, if you wants to put the hdisk1 into mirror with rootvg.
root@nimserver(/)# extendvg rootvg hdisk1
root@nimserver(/)# mirrorvg rootvg hdisk1
