Configuring cluster iSCSI authentication

You can use the SAN Volume Controller Console to configure the Challenge-Handshake Authentication Protocol (CHAP) to authenticate the SAN Volume Controller cluster to the iSCSI-attached hosts. After the CHAP is set for the cluster, all attached hosts must be configured to authenticate this way. To help in problem determination, this step can be delayed until after the first one or two hosts have been configured and their connectivity has been tested without authentication configured.

This task assumes that you have already launched the SAN Volume Controller Console. To configure authentication between the SAN Volume Controller cluster to the iSCSI-attached hosts, follow these steps:

In the portfolio, click Configure iSCSI Authentication. The Configure Cluster iSCSI Authentication panel is displayed.
On the Configure Cluster iSCSI Authentication panel, enter the shared passphrase that is used to authenticate the SAN Volume Controller to the host in the CHAP Authentication Secret field.
Click OK.

After you configure the CHAP secret for the SAN Volume Controller cluster, ensure that the cluster CHAP secret is added to each iSCSI-attached host. On all iSCSI-attached hosts, specify a CHAP secret that the hosts use to authenticate to the SAN Volume Controller cluster.
