To rescan the SCSI bus and re-register all devices found, you need to do the following:
mylinuxhost# echo “- – -” > /sys/class/scsi_host/host#/scan
Replace the “#” with the number of the SCSI bus to be rescanned.
Ex. mylinuxhost# echo “- – -” > /sys/class/scsi_host/host0/scan
mylinuxhost# echo “- – -” > /sys/class/scsi_host/host1/scan
