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