Note: If you run the iSCSI > Target Discover Portal or iSCSI > Target
Discover iSNS command again after the targets are connected, it overrides
the existing connection settings like target credentials. If the target requires
authentication, you will need to enter the target credentials again when the
existing sessions are reconnected. The existing sessions need to be
reconnected if the appliance restarts or when you change the IQN for the
appliance or when the iSCSI processes are restarted etc.
About iSNS
An iSNS server uses the Internet Storage Name Service protocol to maintain
information about active iSCSI devices on the network, including their IP addresses,
iSCSI node names, and portal groups. The iSNS protocol enables automated
discovery and management of iSCSI devices on an IP storage network. An iSCSI
initiator like the NetBackup appliance can query the iSNS server to discover iSCSI
target devices.
