Using iSNS for iSCSI Device Management

You can configure a group to use an iSNS (Internet Storage Name Service) server, which facilitates the automated discovery, management, and configuration of iSCSI devices and other devices on a TCP/IP network.

An iSNS server provides a central management point for the group by dynamically maintaining up-to-date information about the iSCSI target names for group volumes. Once the IP address of an iSNS server is entered in an iSCSI initiator’s configuration utility, the setting is persistent across initiator sessions. There us no need to enter the group IP address or iSCSI target name in the utility.

Note: An iSNS server must already be set up and available on the network in order for the group to access it.

To configure iSNS servers in the group, click:

Group Configuration > iSCSI tab

The Group iSCSI window appears (Figure 13: Group iSCSI ).

In the iSCSI Discovery panel, click Add. In the Add List Item dialog box, specify the IP address for an iSNS server. You can specify up to three IP addresses. Only one server is used at one time. The first server specified is the default server. The other servers are used, in the order specified, if the default server is not available. Use the up and down arrows to change the address order.

Use the ip_address:port format to specify a port number if you are using a port other than the default, 3205.

To modify or delete an address, select the address and click Modify or Delete, as needed.
