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 comfig for /etc/ctl.conf
target naa.2100001b321cd5b6 {
auth-group no-authentication
port isp0
port isp1
lun 0 {
backend block
path /dev/zvol/tank1/export/fc
}
}
Make sure the WWN matches. Next, start the ctld daemon.
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
