OMVS root file system question

This is a 2 part question:

1) Would it be a problem if the OMVS root file system went into secondary extents ? Can it use it ?

2) If I wanted to expand the root file system, how could I copy what was in the root file system into the bigger newly allocated HFS file system?

Assuming the OMVS root file system is HFS, if it goes into secondary extents it'll automatically use them. Not really a problem.

Depending on the z/OS version you may be required to IPL to implement the new root HFS file system. I'd probably use DFDSSDFP to dump the old root into a backup file, then restore into the new file system.

That sounds like a plan. Thanks...
