Mucho Gracis to everyone that responded.  Most people had the correct
answer, or at least were very close.  I even got replies from some
*real* programmers in Austin (:-) ).  In the end, the support line
was where I got the response.  They're good -- use 'em.

The problem turned out to be that the log logical volume hd8 had been
corrupted, hence the failure of the script above.  I had to boot from
diskette and get a shell, run /etc/continue and /etc/aix/logform.
(If you have the same problem call the support line -- it's painless)

As John Carr showed (script portion above) the startup scripts actually
display LED values upon failure, so there is another place to search
for answers on a system failure.  Of course, it doesn't help much if you
only have the one system.
