FreeBSD with a kernel that supports your card, e.g isp(4). a ZFS zvol. Aram Hăvărneanu 2018 11 7 2025 8 28 Create a ZFS zvol This will create a sparse 850GB ZFS zvol. sudo zfs create -p -s -V 850g tank1/export/fc Aram Hăvărneanu 2018 11 7 2025 8 28 Enable ctld(8) sudo sysrc ctld_enable=YES Aram Hăvărneanu 2018 11 7 2025 8 28 Bring the device online Use ctladm(8) to bring the devices online. sudo ctladm port -o on isp0 sudo ctladm port -o on isp1 Aram Hăvărneanu 2018 11 7 2025 8 28 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 Aram Hăvărneanu 2018 11 7 2025 8 28 Configure ctl.conf(5) Use this config for ctl.conf(5): 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 Aram Hăvărneanu 2018 11 7 2025 8 28 Initiator side If using macOS, the mac should just "see" the target, no configuration required.
