You can specify the preferred storage system network interface to be used when establishing an NDMP data connection to another storage system.
By default, an NDMP data connection uses the same network interface as the NDMP control connection established by the NDMP backup application. However, when a data connection between NDMP-enabled storage systems needs to be established over an alternate network, it is necessary to specify the storage system's interface through which the alternate network will be accessed.
For example, a UNIX or NT resident NDMP backup application and multiple storage systems can be interconnected via a corporate network. The same storage systems can also be interconnected via an isolated private network. To minimize load on the corporate network, the ndmpd.preferred_interface option can be used to direct all NDMP data connections over the isolated private network.
To specify the preferred network interface to be used for NDMP data connections, complete the following step.
Note
The ndmpd.preferred_interface option is persistent across storage system reboots.
To disable a preferred network interface specification and force the NDMP default interface to be used for data connections, complete the following step.
