Most of users uses AIX 7.1 on their environment.And most of them want to upgrade their environment to AIX 7.2.Firstly,You upgrade your NIM machine.So,You cannot create spot or lpp source of upper level NIM AIX version.,For example If you want to create AIX 7.2 spot,you dont create.and failed.Beceuse your NIM server’s version is AIX 7.1. So you have to upgrade new version of AIX.

I am using VIOS in my environment.Firstly I create a virtual scsi adapter in my VIOS profile.


After that,I create same adapter with same id  in my NIM server.


Next step , we should create repository because we dont use CDROM to upgrade.I downloaded AIX sources before and upload in my VIOS /home directory by ftp.

To begin with, you ran lsrep command.We dont have any DVD repository.


I have a pool.You can see lssp command.


I have to create DVD repository.You should create with 8G size because we have two dvd and so ı have to create two source.


mkrep -sp rootvg -size 8G

Again you can run lsrep command and you can see your repository.


Maybe you want to increase your repository size and should use below command.


chrep -size 4G

next step we create a virtual dvd to use AIX Udf file.

gmkvopt -name aix72 -file AIX.udf

And you can see lsrep command to your virtual DVD.

After that, we create a virtual DVD-ROM.

ımkvdev -fbo -vadapter vhost17

Earlier we created virtual scsi adapter.Do you remember?I created vhost17.So I use vhost17 with this command.

$ lsmap -vadapter vhost17
SVSA Physloc Client Partition ID
————— ——————————————– ——————
vhost17 U9117.MMD.064B837-V1-C10 0x0000000a

  • then,you should insert your DVD to your virtual DVD-ROM with loadopt command.And then run lsmap command.jloadopt -disk aix72 -vtd vtopt0  / lsmap -vadapter vhost17
  • You should start your NIM lpar to SMS Mode.SMS menu –  press 5
