About the support for multiple IP addresses in NetBackup
NetBackup supports assigning multiple virtual IP addresses to a clustered primary server. After a clustered primary server installation or upgrade, use the bpclusterutil -addIP command to add multiple virtual IP addresses.
If your virtual name resolves into multiple IP addresses, you must add the associated IP addresses using the bpclusterutil -addIP command to make NetBackup work seamlessly.
For more details on the command, refer to the NetBackup Commands Reference Guide.
