True.
What you can normally safely do, is to switch on an off SCSI devices.
(Also this can go wrong if their bus driver hardware is misdesigned and
spits out random signals on poweron.)
BTW, I have a script, which does facilitate the checking for new devices on
http://www.garloff.de/kurt/linux/rescan-scsi-bus.sh
which might be useful for you.
