I'm not sure where raidhotadd is talked about. It is a symbolic link to
raidstart. But, to use raidhotadd, use the following syntax...
raidhotadd raiddev sparedev
where:
raiddev -- is the /dev/md0 type device name of the currently running
raid array.
sparedev -- is the /dev/hda1 type device name of the spare disk to be
added.
