Important: In the event that you IPLed a system with duplicate system volumes, it is
possible that you may have destroyed your saved segments. You will know this is the case
when you cannot IPL CMS. Rather, you will have to IPL 190. To rebuild saved segments, try
the following commands (only do this if your saved segments are trashed!):
==> vmfsetup zvm cms
==> sampnss cms
==> ipl 190 clear parm nosprof instseg no
==> acc (noprof
==> acc 5e6 b

4.12 Restoring your z/VM system from tape
It is good to practice to restore a system. You don’t want to be doing your first restore when
the pressure is on.
Restoring a z/VM system from tape that has the same set of volume labels as the system that
is running is problematic. If there are two z/VM systems on the same LPAR with the same
volume labels, both systems cannot be IPLed cleanly. If you have backed up your system in
section 4.10, “Backing up your z/VM system to tape” on page 64, you can restore this system
to five other 3390-3s. Refer to the Appendix E “Restore the z/VM System Backup Copy from
Tape” in the manual The z/VM Guide for Automated Installation and Service, GC204-6099.
