It was possible to recognize new luns without a reboot before, with a
script like rescan-scsi-bus, or using the proc filesystem ie,

echo "scsi add-single-device X X X X" > /proc/scsi/scsi

Where the X's are, respectively, Controller, Channel, Target, LUN
I admit this isn't a very pretty solution, but if you can avoid
rebooting it may not matter to you.

Now if only linux could get away from it's retarded device name
assignments which are done by order of discovery, and incorperate GFS
linux could become a much bigger enterprise player.
