Setting up a FC target using LIO

How I SetUp a FC Target on Linux

1. Install Fedora 23 & targetcli

Install Fedora 23. Use yum to install the following packages:

yum install targetcli 
yum install scsi-target-utils

2. Configure your FC HBA as a target (not initiator)

The most crucial bit is to verify that the qla2xxx driver has initiator mode disabled — it should be operating in target mode only. You can check this with:

cat /sys/module/qla2xxx/parameters/qlini_mode

It should say ‘disabled’. If it doesn’t, create a file called /usr/lib/modprobe.d/qla2xxx.conf and put:

options qla2xxx qlini_mode=disabled

in it. Then, run ‘dracut -f’ to rebuild your initrd, and reboot.

targetcli won’t let you create a qla2xxx fabric if qlini_mode is wrong.

3. Use targetcli to configure the LUN

Start targetcli by running:

targetcli

Once in targetcli, you can type 'help' to review the available commands and 'ls' to review the current structure.
