How to Connect Cluster Nodes to iSCSI Volumes

After installing Windows 2003 cluster node and the iSCSI initiator, you can connect the node to the shared iSCSI volumes.


1. Run the Microsoft iSCSI initiator from Start > Programs > Microsoft iSCSI Initiator. The iSCSI initiator Properties dialog box appears.


2. Click the Discovery tab and then click Add. The Add Target Portal dialog box appears.
Specify the iSCSI group IP address (or its DNS name). Then, click OK. This will enable
the initiator to “discover” the iSCSI targets associated with the group volumes.


3. In the Microsoft iSCSI Initiator Properties dialog box, click the Targets tab.


4. Select the desired iSCSI target and click Log On. In the Log On to Target dialog box, check
the box next to Automatically restore this connection when the system reboots. If you want to use multipath I/O, in the Log On to Target dialog box, check the box Enable multi-path and then click Advanced. This enables you to specify multiple physical paths to the same target.


5. If the volume requires CHAP credentials, in the Log On to Target dialog box, click
Advanced. The Advanced Settings dialog box appears. Check the box next to CHAP logon
information and specify the required user name and secret (password). The information
must match an access control record for the volume and an entry in a CHAP database set up
in the group or on an external RADIUS server. After entering the information, click OK.


6. In the Log On to Target dialog box, click OK to complete the login.
7. Confirm the connection by clicking the Targets tab in the Microsoft iSCSI Initiator
Properties dialog box. The target should appear in the list with the status Connected.
9. In the Microsoft iSCSI Initiator Properties dialog box, click the Bound Volumes/Devices tab.
To ensure that the volume will be available when the iSCSI service is started by Windows,
click Bind All. Then, click OK. If you have an application that uses drive letters (for
example, SQL or Exchange), perform the bind after assigning a drive letter.

Once the node is connected to a volume’s iSCSI target, it appears as a local disk (iSCSI disk) in
the Disk Management utility.
