By default, all clients are notified when the iSNS server is not available. To disable these notifications, change the Management_SCNs_Enabled property.
Use the “iSNS Server Management” RBAC profile to obtain the authorizations needed for managing the iSNS service.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
Use the svccfg command to disable the property:
# svccfg -s svc:/network/isns_server setprop\config/Management_SCNs_Enabled=no
Reload the server configuration:
# svcadm refresh svc:/network/isns_server
