Connect to a target/volume

Even though you’re connected to the array itself, you still need to tell the initiator exactly which target or volume you want to mount on your local machine. To see the list of available targets on the array you selected, choose the Targets tab.

The iSCSI initiator Target tab in this example has only a single volume available.
To connect to an available target, choose the target and click the Log On button. A window pops up with the target name and two options from which you can choose.

iSCSI target Log On options.
The two options are important. If you want your server to connect to this volume automatically when your system boots, make sure you choose the Automatically Restore This Connection When The System Boots check box. Unless you have a good reason otherwise, you should always select this check box. If you do not, you can’t make the iSCSI target persistent after a reboot and will need to manually reconnect it.
To enable high availability and to boost performance, choose the Enable Multi-path check box. Make sure to understand that multi-pathing (MPIO) requires multiple network adapters dedicated to the iSCSI task, and for maximum availability, you should also have a fully meshed gigabit Ethernet architecture for your storage traffic.
Again, if you are using CHAP or IPSec for communication with a target, click the Advanced button to bring up the Advanced Settings dialog box you saw in Figure D.
Once you finish making decisions regarding how you want to connect to your target, from the Log On To Target window, click the OK button. The target status in the imitator window should change to Connected.

The target is now connected.
