Specifies whether iSNS is enabled on this storage system. If the check box is selected, iSNS is enabled.
Enabling iSNS starts iSNS on this storage system, causes the storage system to register with the iSNS server, and allows the storage system to be discovered by iSNS clients.
Disabling iSNS stops iSNS on this storage system. After a timeout interval (default duration: 5 minutes) with no communication from the storage system, the iSNS server automatically unregisters the storage system.
Note: You cannot enable iSNS unless you also specify the IP address for the iSNS server.
