ps, if working with systemmirror 7.x remember that the ha interfaces will multicast for caa. if you have a lot of systems in a vlan they may be affected..

iscsi_initiator
ISCSI_INITIATOR(4) BSD Kernel Interfaces Manual ISCSI_INITIATOR(4)
NAME
iscsi_initiator -- kernel driver for the iSCSI protocol
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device iscsi_initiator
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
iscsi_initiator_load="YES"
DESCRIPTION
This driver, along with its userspace counterpart iscontrol(8), is obsolete. Users are advised to use iscsi(4) instead.
The iscsi_initiator implements the kernel side of the Internet SCSI (iSCSI) network protocol standard, the user land companion is
iscontrol(8), and permits access to remote virtual SCSI devices via cam(4).
SYSCTL VARIABLES
debug.iscsi_initiator set the debug-level, 0 means no debugging, 9 for maximum.
net.iscsi.isid the initiator part of the Session Identifier.
kern.cam.cam_srch_hi=1 allow search above LUN 7 for SCSI3 and greater devices.
the following are informative only:
net.iscsi.driver_version the current version of the driver.
net.iscsi.sessions the number of current active sessions.
net.iscsi.n.targetname is the targe name of session n.
net.iscsi.n.targeaddress is the IP address of the target of session n.
net.iscsi.n.stats are some statistics for session n
net.iscsi.n.pid is the process id of the userland side of session n, see iscontrol(8).
FILES
The iscsi_initiator driver creates the following:
/dev/iscsi used to create new sessions.
/dev/iscsi%d for each new session.
