Hi,

I said:

What you have then is an unusable volume set (the one the
disk is "removed" from)

It's like saying "a single card is at the bottom of a house of cards...
can I remove it".  The answer is both yes and no ... because it depends
upon unstated assumptions.  Yes, you can remove it...and the house of cards
collapses.  No, you can't remove it without collapsing the house of cards.

What I meant by saying "cannot" was:

   If you take a disk that's a member of an existing volume set,
   and "remove" it from the set (e.g., "scratchvol" or *any* other
   technique), then the original volume set is nearly useless
   (the other disks in the volume set may as well be scratched/re-used)

So, the completely technically correct answer is "yes, you can remove it"...
but the *useful* answer is "no, you cannot" (because what remains behind is
relatively useless).

BTW, you don't have to do a reload (which usually means "restore *all* files
from tape) if you are zapping a user volume set ... at worst, you only
have to restore the files that were on that volume set.

Hope this clears things up :)
