== Introduction ==
You need:
* FreeBSD* with a fiber channel card kernel that supports target modeyour card, e.g. [[FreeBSD kernel with Fibre Channel target mode support for QLogic cards | for QLogic QLE2462]]* a fiber channel card that supports target mode
* a ZFS zvol
sudo zfs create -p -s -V 850g tank1/export/fc
== Enable ctld ==
sudo sysrc ctld_enable=YES
== Bring the device online ==
sudo ctladm port -o on isp0
sudo ctladm port -o on isp1
== Check the WWN address ==
You'll get output like:
z800:aram$ sudo ctladm port -l
Port Online Frontend Name pp vp
0 YES camsim camsim 0 0 naa.50000009e370df01
1 YES ioctl ioctl 0 0
2 YES tpc tpc 0 0
3 YES camtgt isp0 0 0 naa.2100001b321cd5b6
4 YES camtgt isp1 0 0 naa.2101001b323cd5b6
== Configure /etc/ctl.conf ==
Use this config for /etc/ctl.conf:
lun fibre-channel {
backend block
device-id "5000c5001d5ba30b"
serial "MGKSERIAL0001"
option vendor "MGK"
option product "FC Disk"
option naa "600A0B80002682A8000067D95897A544"
option removable "on"
path /dev/zvol/tank1/export/fc
}
target naa.100000062b1b88c8 {
auth-group no-authentication
port mpt0
port mpt1
lun 0 fibre-channel
}
Make sure the WWN matches. Next, start the ctld daemon. The device-id is from a real Seagate FC disk, and the naa is from a real array. I think both are required by macOS to make multipathing work.
sudo service ctld start
Query the status, to see if everything is working correctly:
z800:aram$ sudo ctladm devlist -v
LUN Backend Size (Blocks) BS Serial Number Device ID
0 block 1782579200 512 MYSERIAL 0 MYDEVID 0
lun_type=0
num_threads=14
file=/dev/zvol/tank1/export/fc
ctld_name=naa.2100001b321cd5b6,lun,0
scsiname=naa.2100001b321cd5b6,lun,0
== Initiator side ==
If using macOS, the mac should just "see" the target, no configuration required.
