Using the Microsoft iSNS Server to Discover Registrations
Use the Microsoft iSNS server to discover the iSCSI initiator and iSCSI targets on the dedicated
network. When the iSCSI Initiator and iSCSI targets have registered with the iSNS server, they
automatically start discovery of the registered devices by querying the iSNS client/server via
TCP/IP. A database of these registrations is also maintained.
Installing and using the iSNS server consists of these procedures, explained in separate subsections:
• Installing the iSNS server
• Using the iSNS server to discover registrations
Configuring the iSCSI Initiator and Target for iSNS Server Usage
Follow these steps:
1. Issue showport -iscsi to verify whether the iSCSI target ports are configured for the iSNS
server; for example:
2. Set up the IP addresses for iSNS; for example:
# controliscsiport isns 10.0.0.60 0:1:1
# controliscsiport isns 10.0.0.60 1:1:1
3. Verify the configuration setting for iSNS; for example:
4. Use the Windows Server 2012/2008 Add Features wizard to add the Internet Storage Name
Server feature.
5. Once the iSNS server is installed on another Windows Server 2012/2008 server, open the
iSCSI Initiator, click the Discovery tab. In the Discovery window, click the Add Server... button
in the iSNS servers area.
6. Enter the IP address or DNS name, and then click OK.
