The Linux SCSI and software RAID layer handles hotswap just fine. I
did it once on a RAID0/5 array. You just have to signal Linux's SCSI
layer so that it notices the change, as is described in section
"Hot-swapping with SCA" of
http://www.tldp.org/HOWTO/Software-RAID-HOWTO-4.html#ss4.2. (These
were the days before udev, so this *might* have become more automatic
now.)
