Configuring NetBackup Flex Scale in a non-DNS environment

Starting with NetBackup Flex Scale 3.0, enabling the DNS server is optional. Cluster nodes can be configured without the DNS server IP. If you do not want to specify a DNS server, you can specify the IP address, or the FQDN, or the short host name details and these details are communicated to the NetBackup services and all the cluster nodes using multiple set of APIs.

You can use the Network > Custom Hosts menu to add IP/FQDN details for clients and IPs for which FQDN mapping is not present in the DNS server. This information can be added to the cluster nodes or NetBackup services or both. A hosts file is used to map IP addresses and its FQDN so that the system can resolve addresses quickly without querying the DNS. You can select cluster nodes or NetBackup services as an option to add IP/FQDN information.

You can perform the following operations using the NetBackup Flex Scale GUI:

  • Add IP/FQDN to cluster nodes. Go to Network > Custom Hosts. Click Add to add additional IP/FQDN entries to the configuration. In the Add custom hosts entries form, add the entry. In the Apply to field, select Cluster nodes.

    You can use the Advanced tab to add multiple IP/FQDNs entries at the same time.

  • Add IP/FQDN on NetBackup services containers. Go to Network > Custom Hosts. Click Add to add additional IP/FQDN entries to the configuration. In the Add custom hosts entries form, add the entry. In the Apply to field, select NetBackup services.

    You can use the Advanced tab to add multiple IP/FQDNs entries at the same time.

  • Add IP/FQDN on cluster nodes and NetBackup services containers. Go to Network > Custom Hosts. Click Add to add additional IP/FQDN entries to the configuration. In the Add custom hosts entries form, add the entry. In the Apply to field, select both Cluster nodes and NetBackup services.

    You can use the Advanced tab to add multiple IP/FQDNs entries at the same time.

  • Delete IP/FQDN information from cluster nodes. Click on the Actions button (vertical ellipsis) on the right side of the IP address and select Delete.

  • Delete IP/FQDN information from NetBackup services. Click on the Actions button (vertical ellipsis) on the right side of the IP address and select Delete.

  • Delete IP/FQDN information from cluster nodes and NetBackup services. Click on the Actions button (vertical ellipsis) on the right side of the IP address and select Delete.
