How to create offline repository for AIX 7.1

Hello everyone, Im relatively new to AIX systems. I currently have two power servers in isolated network.
I managed to setup AIX 7.1, however i was presented with two AIX DVD-01 and DVD-02, i thought they were both required for installing AIX. However i found that AIX was installed using only DVD-01. DVD-02 was never been able to be burned on USB using rufus.
Now im having the following difficulties:
1- I found that many packages arent installed by default like openSSH, Bash Shell
2- I cant find a way to use the installation ISO file as a local repository as in linux distributions.

I saw that there are something called expansion pack but don't know how to get it, im not sure in it is the DVD-02 ?

I need help to build the local repository for AIX.
Thnaks in advance.

Hi gebo. Thanks for your question and welcome to the forums. A reminder that there is no need to post a question in multiple forums. The release notes for 7.1 contain a lot of the information you're looking for IBM Documentation including installation of OpenSSH. Hope this helps. Cheers, Keith
