Adding and Removing LUNs Dynamically
------------------------------------
It is possible to add and/or remove LUNs on the target without restarting
target or initiator. This can be done either via scstadmin or directly via the
sysfs interface. Although the SCST core will notify the initiator about LUN
changes, Linux initiators will ignore these notifications. In order to bring a
Linux initiator again in sync after a LUN change, the initiator has to be told
to rescan SCSI devices. Rescanning SCSI devices is e.g. possible via the
rescsan-scsi-bus.sh script that can be found here:
