Device reconfiguration procedures
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.
