Most of the ones I swap are SCA (scsi w/hot swap connector).
But, the other quirk is that I very often clone these
machines by dd'ing the entire drive, so no matter how
clever you are about creating unique labels there will
be duplicates when the raw disk is copied. What we
need are some management tools so you have standard
procedures to clone machines across linux distributions
instead of every distro re-inventing its own quirky
workaround for the scsi device naming problem and
hiding MAC addresses in obscure config files.
Unfortunately no one seems to be interested in that kind
of cooperation. If a disto does add something it wants it
to be unique to their version and a reason to use only
that version. However, I'm not interested in being married
to only one distribution so I stick to dd / tar and the
things that work everywhere and simply complain about
the way different unix flavors have always kept their
differences to the detriment of acceptance.
