Additional Notes

Device reconfiguration procedures for FC and FCoE

	There are three methods to reconfigure the devices added or removed
	in the system.
	Method 1:
	Reboot the system :
	shutdown -r now
	Method 2:
	Remove and reinsert the modular driver
	For example:
	modprobe -rv qla2400
	modprobe -v qla2400
	Method 3:
	Use QLogic script to dynamically scan the devices. QLogic has the
	QLogic FC HBA LUN Scan Utility which is available from the
	EMC-approved site on the QLogic website.
	Note: It is highly recommended that a rescan of the SCSI bus should not be
	conducted while you are running IO. The dynamic discovery and insertion of
	LUNs while IO is running on applications may cause unforeseen errors to
	occur on the IO in flight. The benefit of the dynamic scanning of the SCSI bus
	is to reduce the need to reboot the server.
Usage examples
	◆ To re-scan all the adapters, enter one of the following commands:
	# ./ql-dynamic-tgt-lun-disc.sh
	# ./ql-dynamic-tgt-lun-disc.sh -s
	# ./ql-dynamic-tgt-lun-disc.sh --scan
	◆ To re-scan and remove any lost LUNs, enter one of the following
	commands:
	# ./ql-dynamic-tgt-lun-disc.sh -s -r
	# ./ql-dynamic-tgt-lun-disc.sh --scan --refresh
	To invoke the menu, enter one of the following commands:
	# ./ql-dynamic-tgt-lun-disc.sh -i
	# ./ql-dynamic-tgt-lun-disc.sh --interactive
