Quick Start
-----------

Copy sample configuration files after installation.

# cd /usr/local/etc/istgt
# cp auth.conf.sample auth.conf
# cp istgt.conf.sample istgt.conf
# cp istgtcontrol.conf.sample istgtcontrol.conf

Edit istgt.conf.
3 sections below at least need modification against your own copy of
istgt.conf.sample.

[PortalGroup1] IP address
[InitiatorGroup1] Initiator name and netmask
[LogicalUnit1] LUN0 allocated file name and size

[PortalGroup1]
  Portal DA1 192.168.2.36:3260

Replace 192.168.2.36 with your server IP.
Because 3260 is standard iSCSI port, 3260 does not need modification.

[InitiatorGroup1]
  InitiatorName "iqn.1991-05.com.microsoft:saturn"
  Netmask 192.168.2.0/24

Replace "iqn.1991-05.com.microsoft:saturn" with your allowed initiator
name and 192.168.2.0/24 with your allowed IP or CIDR.
If you need any initiator names or IPs, use special word ALL instead.

[LogicalUnit1]
  LUN0 Storage /tank/iscsi/istgt-disk1 10GB

Replace /tank/iscsi/istgt-disk1 with your correct path and 10GB with
the size you want.
You can specify the size also with MB or TB.
When the device file (/dev/ad1, /dev/zvol/tank/vol, etc.) is specified,
Auto can be specified for the size.

After finishing to edit istgt.conf, start daemon by the script.

# /usr/local/etc/rc.d/istgt forcestart

Check messages on terminal and syslog (usually /var/log/messages).
An error message may only appear at syslog.

Add istgt_enable="YES" to /etc/rc.conf.

You have done.
