YMMV. The dual controller FC10 confused the shit out of the
Emulex lpfc driver. lpfc just doesn't know the FC10 might take
5-10 (or more)  seconds to reassign LUNs from one controller
to the other.  I don't expect much better from the SCSI stack
but it will depend on the interface driver.

At boot time, such a scan takes place.
You can look in /proc/scsi/scsi to see which SCSI devices have
been discovered.

See Debian scsitools and scsiadd packages.
Also learn about mounting file systems by label rather than
by device name
