there is a wonderfull document:
http://people.redhat.com/nayfield/storage/RHEL4Storage.html

from where I highlight this:

If you need re-do a SCSI scan, you can do


echo "- - -" > /sys/class/scsi_host/host0/scan


Where host0 is replaced by the HBA you wish to use.
You also can do a fabric rediscover like this:


echo “1” > /sys/class/fc_host/host0/issue_lip
echo "- - -" > /sys/class/scsi_host/host0/scan

This will send a LIP (loop initialization primitive)
to the fabric.
