SUMMARY E3500 not seeing some of its internal drives

Hi all,

My thanks to:

Justin Stringfellow for confirming that probe-fcal-all would prove to be

William Enestvedt for providing some more information on what things are
supposed to look like and the following two links for drive information, and general
information about the 3500

Vikas Khator for a suggestion (that drives get their power from the
fibre channel) that I was going to pursue after my musical chair dance
with fibre cables and plugs.

probe-fcal-all showed both sbus-es, but only populated the lower plane.
I swapped the fibre patch cords around: no change.  I swapped the GBIC
plugin modules (or whatever they're called) on the IO board (between 0
and 1): no change.  I moved the GBIC modules from LA to LB and UA to UB,
and no change (well... the machine wouldn't boot any more, but I still
only saw the same disks).  I swapped the GBIC modules between LA and UA,
and now I saw the upper plane.

Note: if you're swapping fibre patch cords around, and probe-fcal-all,
you might end up with a hung machine (from the ok prompt, so not a BIG
big deal...).  Sometimes it might look like it's hung, but it returns
after a couple of minutes.  Sometimes moving a cable is not as
hot-swappable as you might like.  The secret is not to freak when all
your drives disappear after you've made a change...

Anyway: it seems like I need a new rinky-dink fibre module insert whammy
(or whatever they're called).
