What Volume Groups Are Backup Up by the Mksysb Process?

I have a system that appears to have become corrupted since the last mksysb image was taken. I'd like to restore the system from that image, but I'm wondering what will happen to the non-rootvg volumes. It has always been my understanding that the mksysb backs up only the root volume group. Am I mistaken?

You're right,

mksysb backs up the root volume group "rootvg" and nothing else.

The process to back up other volume groups is called "savevg".

So the content of the other volume group will not be touched during the restoration, correct?
