Tracy Johnson makes an excellent point about the use of NOT1 class name.

So, to move files OFF ldev1, simply store some fileset, then restore with
the ;dev=not1 option.

Works fine with MPE-named or posix-named fileset.

As Bill Lancaster pointed out, you do run the risk of moving some
ldev1-required system files off of ldev1.

To solve this potential problem (more on that later) you could simply
create an SLT tape and UPDATE from it.

Whether or not a problem is created by moving files off ldev1 is debateable.

I have recently intentionally placed such a file, NMCONFIG.PUB.SYS
intentionally on ldev 2. A subsequent "start norecovery" worked without
incident.

I suppose, in that case a "start norecovery single-disk" would be
problematic - haven't tried it.

In any case, creating a new SLT and updating from it (or simply updating
from a recent unmodified SLT) should correct any problems associated with
system files straying off ldev 1.

One final point. I prefer to have at least 60000 contiguous free sectors on
ldev 1 prior to any update. Current versions of MPE/iX are supposed to warn
you if you do not have enough free space on ldev 1 to perfrom an update.
At least, I believe you are warned - I have never tried to tempt faith in
this regard. If I ever do have the opportunity to test it out, I'll let you
know.
