I guess that I should have read a little further into the noroll
procedure. It looks like it takes the cluster to run level 2. So no
option for network and ssh... (unless I cheated and manually brought it
back; which would probably be a dumb/untested move).
Thanks to all who responded.

It looks like the documentation says that you have to use multiuser-mode
if choosing no-roll.
PatchInstallGuide, Chapter 5.1:
"In addition, the no-roll patch procedure employs the use of the Tru64
UNIX Event Management System (EVM) to send cluster-wide events. As a
result, patches must be applied to the system in multiuser mode. If you
attempt to use the no-roll procedure while in single-user mode, you will
be advised to change the cluster to multiuser mode before continuing."
OK, then I am all set. But... I don't trust (possibly) aging
documentation (yes, it is from the patch kit itself, but...)
Any experiences? (thanks to all that have replied so far).

Question: installing patch kit 5 in multiuser-mode/no-roll with the
following performed:
1. only I can login and sudo my way to root (I would also use "screen"
to protect against disconnect)
2. all applications (i.e. oracle) is down, but normal system daemons are
running and network is up.
Is this a very bad idea (i.e. multiuser mode vs. single user method)?
If I can do it in multiuser mode, (i.e. without having to stand at the
dumb terminal), I can work more efficiently on the 8 boxes that I need
to upgrade (some are cluster members).
Thanks for your experiences/insight.
