That seems to have done the trick; I ran it with a -m option, and it
listed well over 100,000 file to be backed up. It ran to end of tape
rather quickly; or at least I'm assuming it reached EOF, otherwise
something else killed it. Regardless, I did not kill the job, but when
I got the prompt back, I created an exclude file to omit a large
directory in rootvg that isn't needed for an OS recovery.

Then kicked off the mksysb again, this time specifying the exclude
file, and it listed @56000 files to back up and ran to successful
completion. Took about 4 hours.

So thanks to both you and Hajo for all your help; I'm gonna try and
figure out how to make it run quicker (specify a blocking cfactor?
Find other files to exclude?); but for now I'm happy that I have a
mksysb!

Thanks again;
