RE: Three drive raid set.

[rob@xxxxxxxxx]

I realize you're just beating your chest about how you are maintaining 
your own hardware.  But getting back to the point, I don't think you can 
hot swap a mirrored set.  I still remember the look on an executives face 
at a shareholders dinner that we did a hot swap on one of his raided 
drives during that day.  He never noticed it.

I've been known to do a few card swaps, live.  But we don't stock our own 
disk drives.  And most of the card swaps were yanking them out of our 840 
prior to it going out of production and putting them into the 570 prior to 
it's going into production.  That was kind of fun.

You still call out somebody from IBM to do drive swaps?? We've done that
ourselves (actually, I've done it myself) for quite a few years. And as I
recall, I may have done a hot-swap on part of a mirrored pair. Or I might
have simply done it when it was convenient to re-IPL to DST. I forget, but
it was one or the other; what I do know is that only one of our boxes is
physically hot-swappable anyway.
