This is a more recent z/Series machine; it may well be running Linux
on the Support Element rather than OS/2.
But Guy is 100% correct; all the support and configuration stuff there
is critical to preserve exactly as-is. Recreating it from backups or
reinstalling it from scratch is not for the faint-hearted. A lot of it
is very arcane stuff, for IBM service engineers only; don't forget,
there's stuff in there IBM charge big money for - enabling and
disabling CPUs and memory. You want more CPU in your mainframe? You
pay IBM $50k or whatever and they send an engineer round to turn it
on... ok it can be done remotely too these days but point taken;
there's a lot of stuff in there that's critical, undocumented,
specific to the individual machine, and never supposed to be touched
by anyone outside IBM...
