Now anytime the system boot and QLA card is plugged, modules will load
automatically.
When driver is loaded, enable all logical units to work in target mode
When driver is loaded, enable all logical units for each channel to work in
target mode. You need to write string in form "channel:enable" to procfs
configuration file, ie:
$ echo 1 > /proc/scsi_tgt/qla_isp/0
$ echo 0:1 > /proc/scsi_tgt/qla_isp/0
(to unload isp_mod.ko module you must write 0 to this file).
This is not switching target/initiator role. If you have more then one device,
role of each you can set using isp_roles parameter, like in example:
To unload isp_mod.ko module you must disable target mode for all channels ie:

$ echo 1:0 > /proc/scsi_tgt/qla_isp/0
Enable/disable target mode is not the same as switching target/initiator role.

parameter, like in example:
$ modprobe isp_mode isp_roles="b0300=initiator"
