Thank you for the explaination.

However, what does it all mean ?   Why do I get error message that try to
address 20-different possibilities of reasons for some failure, that I am
not sure I am having ?

What does it all mean  to me ?

Should I just call IBM and have them come figure it out ?      The last
time I did that, all IBM did was talk me through simple troubleshooting
(unplug drive from slot a - plug it into slot b - did that make the
problem go, bad drive - we will send you a new
plug it in) !  While I don't mind this to a point (I get my hand dirty,
all the time), there is a point beyond simple troubleshooting that someone
more techincally intimate with the equipment needs to address !
