As for my first question they all pointed me to isainfo.  Thanks.
It appears this is not an early indication of disk problems.  Whew.

The only "solution" I was given was to try "boot -f".  I did so, and it
did not look like it did anything different than a normal boot, but the
problem has not resurfaced.  I'm not sure that means anything as the problem
only occurred occasionally anyway.

Other answers were:

I was told to check /var/adm/messages to see whether the box has rebooted
itself (appears not), and to

	grep -i bad   /var/adm/messages*
	grep -i score /var/adm/messages*

(bad and score not found)
