md is meta-disk, I assume. Solaris DiskSuite, which is structured
more or less similarly, uses the same term. The idea is that /dev/sd#
is a scsi disk, /dev/hd# is a hard disk, and /dev/md# is a meta-disk,
in the sense of being a virtual construct.
Solaris DiskSuite uses commands like metadb (for manipulating the
descriptive database), metastat, and the like.
Notice that "md" isn't any less obvious than "raid" if you don't
already know what it stands for.
I rather like "md[something]" as long as the devices are going to be
called md, since it ties everything together.
