Veritas NetBackup™ Appliance High Availability Reference Guide

• New deployments

  This method is used for new installations. These deployments require two identical 53xx compute nodes (models) that use the same software version.

• Converting existing systems to HA

  This method lets you use an existing operational 53xx appliance as the first node. Then, add a new 53xx compute node to complete the HA setup. These systems also require two identical 53xx nodes that use the same software version.

The following describes the basic hardware connectivity, software compatibility, and configuration requirements for an HA setup:

• Hardware connectivity

  • The 53xx nodes are connected to each other using the NIC3/eth2 and NIC4/eth3 Ethernet ports.

  • Both 53xx nodes are connected directly to the Primary Storage Shelf.

• If you use any third-party servers in the working environment, make sure that the HA configuration works correctly with the servers. The following tasks, along with others may be necessary:

  • Add the necessary information of the HA configuration.

  • Connect the hardware properly.

  • Grant the required access for the HA configuration.

  • Configure the necessary information on both nodes in the HA setup.

• Software version compatibility

  • If the primary server is a traditional NetBackup primary server, it must use software version 8.1 or later. If the primary server is a 52xx appliance, it must use software version 3.1 or later.

53xx node configuration

• The two 53xx nodes must use the same software version, 3.1 or later.

• The primary server must use the same or a later software version than the 53xx nodes; 3.1 and later for a 52xx appliance primary server, or 8.1 and later for a traditional NetBackup primary server.

• The first 53xx compute node is configured using the traditional initial configuration process. After the initial configuration is complete, configure the HA setup with this node.

• The partner node only requires network and time zone configuration. After the configuration is complete, add the node to the HA setup.

• NetBackup Appliance HA configurations do not support a pure IPv6 setup. If you plan to configure an IPv6 address on the public network interface card (NIC) on the compute node, you must also do the following:

  • Configure an IPv4 address on the same NIC.

  • Use the IPv4 address to configure the HA setup.

Active Directory configuration

• If you plan to use Active Directory (AD) authentication, set up the HA configuration only after you first update the AD server with the following information:

  • The network information of the node you use for the setup

  • The new host name and the matched IP address

  • The network information of the partner node

NetBackup client updates

• If you use a NetBackup client to manage the NetBackup jobs, add the following information in the bp.conf file on the client:

  • The host name of the first configured node

  • The new host name

  • The host name of the partner node
