[root@proj ]# make -C scstadmin -s install
+ Initiator and target modes
+ The qla2xxx_scst module has parameter "qlini_mode", which determines when initiator mode will be enabled.
+ Possible values:
+
+- "exclusive" (default) - initiator mode will be enabled on load, disabled on enabling target mode and then on disabling target mode enabled back.
+- "disabled" - initiator mode will never be enabled.
+- "dual" - initiator mode will be enabled. Target mode can be activated when ready (only qla2x00t-32gbit).
+- "enabled" - initiator mode will always stay enabled.
+
+
+
+ Usage of mode "disabled" is recommended, if you have incorrectly functioning your target's initiators, which if once seen a port in initiator mode, later refuse to see it as a target.
+
+
+qla2x00t (old qlogic driver):
+ Use mode "enabled" if you need your QLA adapters to work in both initiator and target modes at the same time.
+ You can always see which modes are currently active in active_mode sysfs attribute.
+ In all the modes you can at any time use sysfs attribute ini_mode_force_reverse to force enable or disable initiator mode on any particular port. Setting this attribute to 1 will reverse current status of the initiator mode from enabled to disabled and vice versa.
+
+qla2x00t-32gbit (new qlogic driver):
+ Use mode "dual" if you need your QLA adapters to work in both initiator and target modes at the same time. In this mode, each qlogic host has individual qlini_mode, ql2xexchoffld, ql2xiniexchg attributes that can be changed dynamically.
+ For example, you can change qlini_mode to "disabled" for specific qlogic host:
+ echo "disabled" > /sys/devices/pci0000:80/0000:80:02.0/0000:81:00.0/host1/scsi_host/host1/qlini_mode

To see the device on the initiator we have to add it in the LUNs set of our
target.
We must have a LUN with number 0 (LUs numeration must not start
