Introduction
You need:
- FreeBSD with a kernel that supports your card, e.g. for QLogic QLE2462
- a fiber channel card that supports target mode
- a ZFS zvol
Create a ZFS zvol
This will create a sparse 850GB 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.
