Data network configurations
All the NetBackup operational data traffic, including communications with external hosts and services, is routed on this network. A data network is required to set up the cluster.
Note:
Ensure that the IP addresses and FQDN that you specify are added to the DNS server that you specify here and are resolvable on the network.
The
fd00:200/120network is reserved and used internally by NetBackup Flex Scale, and it should not be used anywhere.A single NetBackup Flex Scale cluster supports up to 16 secondary data networks.
If disaster recovery is configured using NetBackup catalog replication, additional data networks can be added and managed independently on each NetBackup Flex Scale cluster. But when an additional data network is configured with a new NetBackup primary server FQDN, it must be first configured on the cluster where the NetBackup primary server is running (primary cluster). You can add an additional data network on the secondary cluster only if the FQDN is not provided or if it already exists on the primary cluster. Else, the operation to add the additional data network fails.
In a multi-VLAN environment, AIR target domain is supported only on the primary VLAN network. It is not supported on the secondary VLAN network.
You can configure a cluster without a DNS server.
See Configuring NetBackup Flex Scale in a non-DNS environment.
The following types of data network configurations can be done on NetBackup Flex Scale
Plain device (eth5)
VLAN on eth5
Bonded interfaces (bond0 using eth5 and eth7)
See Network configuration on bonded interfaces (bond0 on eth5 and eth7).
VLAN on bond (VLAN on bond0)
To list data networks
- Navigate to Settings > Network > Data Network.
Note:
If you have configured disaster recovery, See Support for multiple VLAN when disaster recovery is configured.
