I don't like mpxio disk names -- they make me work too hard and create fear of
doing the wrong thing.
Long hex strings are much harder to distinguish than short strings and it's
much easier to get confused between two devices. humans are reasonably good
at dealing with dense sets of small integers, and not quite so good at dealing
with sparse sets of 64-bit and 128-bit values.
are c2t5000C5002C68468Bd0 and c2t5000C5002C68468Bd0 the same or different?
what about c2t5000C5002C68203Bd0 and c2t5000C5002C689ABFd0?
are c2t5d0s0 and c2t6d0s0 the same or different? how about sd5a and sd5a?
how much time did each of those comparisons take you? how quickly were you
sure of your answer?
The important part to me is that the 000C5002C68468B above is
typically printed on the label of the drive. Put a little sticker on
your sled with the contained WWN, and you won't make the mistake of
grabbing the wrong drive from the array again. (They need a support
group for that)
