Veritas NetBackup™ Appliance High Availability Reference Guide

Configuration requirements for features and options in NetBackup appliance high availability setups

In most cases, features and options are configured only on the node that runs the MSDP services. This node is the first high availability (HA) node that you configure and is also used to create the HA setup.

Some features and options require configuration on both nodes to ensure correct operation in switchover or failover scenarios. The configuration settings for each of these features or options must match. If you change the settings on the MSDP node, you must make the same changes on the partner node.

The following describes the features and the options that require configuration on both HA nodes:

For complete details about enabling the Security Technical Implementation Guides (STIG) feature, see the NetBackup Appliance Commands Reference Guide.

You can enable the Federal Information Processing Standard 140-2 (FIPS) feature on both nodes only after you have completed configuration of the HA setup. The FIPS configuration must match on both the nodes. If FIPS is enabled on either node before the HA setup is completed, you must disable FIPS on that node before you complete the HA setup.

You must disable FIPS on both the nodes before removing the node from the HA setup

The user and the user group registration for Active Directory (AD) and Lightweight Directory Access Protocol (LDAP) servers on both nodes must match. For complete details about authenticating AD and LDAP users, see the NetBackup Appliance Security Guide.

After the HA setup has been created and the partner node added to it, you can configure and enable the NetworkAccessControl feature. You must configure this feature manually on both appliance nodes and the configurations must match. For complete details, see the NetBackup Appliance Commands Reference Guide.

The pd.conf file stores the deduplication settings for MSDP. To ensure the quality of the data deduplication in an HA configuration, the files on both nodes must match. Otherwise, the deduplication performance may degrade after a switchover. For complete details about editing the MSDP pd.conf file, see the Veritas NetBackup Deduplication Guide.

For complete details about configuring OpenStorage (OST) plug-ins, see the NetBackup Appliance Administrator's Guide.

For complete details about configuring Virtual Local Area Networks (VLANs), see the NetBackup Appliance Administrator's Guide.

If the Veritas Cluster Service (VCS) is unable to bring any service online on an HA node, its service group may go into a faulted state. If any resource is in a faulted state or is offline when it should be online, contact Veritas Support for assistance.
