Configuring and managing iSCSI targets
iSCSI targets
An iSCSI target is any device that receives iSCSI commands. The device can be an end node, such as a
storage device, or it can be an intermediate device, such as a bridge between IP and Fibre Channel
devices.
Each iSCSI target is identified by a unique IQN, and each port on the controller (or on a bridge) is
identified by one or more IP addresses.
As the client system, the initiator initiates disk I/O. It communicates with the target and the target serves
the initiator by providing resources to the initiator.
After you have configured your iSCSI initiator and verified that your network interface is working and that
you can access your target, you need to log into your target to establish your connection.
To do this, you must:
•
Perform a login to the target (adding a target)
•
Reboot the system
Methods to add iSCSI targets
After your initiator has been configured you need a process that shows how to make an iSCSI target
available to that initiator host. The Discovery process presents an initiator with a list of available targets.
The discovery method is the way in which the iSCSI targets can be found.
The discovery methods used for discovering targets are:
•
SendTargets discovery
•
Manually configured targets
Using SendTargets to add an iSCSI target
SendTargets is a method that asks an iSCSI target to provide the list of Target names that can be logged
into by the Initiator. The iSCSI initiator then uses the SendTargets feature to perform the device discovery.
Use this method if an iSCSI node has a large number of targets.
When adding an iSCSI Target, if you leave the iSCSI Target Name option blank, you can use the iSCSI
SendTargets mechanism to add a target.
Manually configuring an iSCSI target
Use this method if an iSCSI node has a small number of targets, or you want to restrict the targets that an
initiator can access. To manually configure a target, you must supply the iSCSI Target Name.
