Network Path Control
To connect multiple subnetworks to networks in the NAS environment, configure the appropriate path
information between the
ETERNUS DX and the client. If the settings are not correct, path control does not work
and connection fail or data transfer takes long time because the appropriate path is not selected.
If the NAS interface of the ETERNUS DX is accessed via a gateway from a client on a different network, set the
gateway when configuring the NAS interface.
A gateway can be configured for each NAS interface.
If a gateway has been configured for the NAS interface and different routes are to be used for specific clients and
networks, set a different static route for each specific client and network.
Configure a network so that the same NAS interface is used to send and receive traffic from the client.
Network configurations that use different NAS interfaces to send and receive traffic (asymmetric routing) are not
supported.
