Why is my VIO mksysb so huge!?

One thing that is great is having a VIO media repository. You can store AIX base media, mksysb images or any other .iso image in your VIO repository.
There is a good post on how to do it here:
I always schedule mksysb backups to go to a NIM server regularly. One thing I take a mksysb of is the VIO servers' rootvg.
The process is to:
- Mount an NFS filesystem (ie /export/nim/mksysb) to the VIO server
- Run the backupios to a file on the NFS mount
- Un-mount the NFS mount from the VIO server
- Define the VIO mksysb as a NIM resource
This can all be easily scripted. The easiest way to do it is to setup passwordless SSH to the HMC and use the HMC command viosvrcmd.
When you want to do a restore, you can extract the spot from the VIO mksysb, then run a restore if you need to.
The problem is that if you have your VIO media repository in the rootvg, then it's going to be included in your mksysb and your mksysb backup will become huge. The answer is to put the -nomedialib option on your mksysb command.
backupios -file /mnt
