Configuring NetWorker Server in a multihomed environment

This section provides an example of how to configure NetWorker in a multihomed environment when the NetWorker Server and the storage node have 2 NICs that communicate through different networks.

The following figure provides a graphical representation of the environment.

Complete the following steps to configure the multihomed environment:

  1. Update the Aliases attribute in the Client resource for the NetWorker Server to include the FQDN and the shortname for each NetWorker Server NIC. This figure shows the values in the Aliases attribute.

  2. Create a Client resource for the storage node. Update the Aliases attribute to include the FQDN and the shortname for each storage node NIC. This figure shows the values in the Aliases attribute.

  3. Update the Storage Nodes attribute for each Client resource in VLAN1 to contain the hostname of the NIC for the storage node to which the client connects. For example, for NetWorker Client VLAN1_client, specify the storage node hostname sn1. This figure shows the values in the Storage Nodes attribute.

  4. Update the Aliases attribute for each Client resource in VLAN1 to contain the FQDN and shortname of the client. The Server network Interface attribute must contain the hostname of the NIC for the NetWorker Server to which the client connects. This figure shows the values in the Aliases and Server network interface attributes.

  5. Update the Storage Nodes attribute for each Client resource in VLAN2 to contain the hostname of the NIC interface for the storage node to which the client connects. For example, for NetWorker Client VLAN2_client, specify the storage node hostname sn2. This figure shows the values in the Storage Nodes attribute.

  6. Update the Aliases attribute for each Client resource in VLAN2 to contain the FQDN and shortname of the client. The Server network Interface must contain the hostname of the NIC interface for the NetWorker Server to which the client connects. This figure shows the values in the Aliases and Server network interface attributes.
