Hi,
  I'm following up to my own message. Will like to clarify the problem
further. 
(1) I have the release notes for the upgrade, thanks to a kind person,
to whom I have been trying to send a reply thanking him, but which get
bounced back faster than my check.
(2) Yes, I did put the machines into single-user mode, et. al. I got one
computer successfully working, and was trying the same procedure on the
other.

  I finally got the other working too, but the procedure I followed is not
consistent with COMPUTERS, which supposedly have a binary behaviour. What
I found was that if I completely shut my system off, and reseted the SCSI
connections, I could extract one, or maybe more, subsets after I bring the
computer back up. Sometimes I had to shut it down and bring it back up
a few times before this happened. Anyway I got them all up before Monday
(today).

  The only thing that I can understand from this behaviour is that there
is some hardware problem in my SCSI tape connection. I am going to try to
extract the software subsets on my other machine to see if the tape is
messed up. I am still curious to know if software subsets that have been
installed using the setld command on a computer can in any way be extracted
back onto tape.

   Thanks, all.
