Step 15
Configure the iSNS Client on the Storage System
(Windows Environments Only)
iSNS (Internet Storage Naming Service) provides the same function as the Simple
Name Server (SNS) service in a Fibre Channel fabric - automated discovery,
management, and configuration of iSCSI devices. It eliminates the need to manually
configure each individual storage system with its own list of initiators and targets.
iSNS is supported only for Windows iSCSI environments.
iSNS includes an iSNS server component and iSNS client component. The iSNS
server must reside somewhere within the IP storage network, for example, on a host
or in the switch firmware. An iSNS client resides on both the iSCSI storage system
and any iSCSI servers connected to the storage system. When you start the storage
system, the iSNS client on the storage system gathers all the storage-system iSCSI
port information and stores it locally on the storage system. When you add a server
to the storage system’s iSNS configuration, Navisphere Manager establishes a
connection from the storage system to the iSNS server, and then registers the
information stored on the storage system with the iSNS server.
Use Navisphere Manager to configure the iSNS environment on the storage system,
as described in the chapter on managing iSCSI storage systems in the
