Considerations for using IPv6 addresses

Note the following if you plan to configure a NetBackup Flex Scale cluster using only IPv6 addresses:

NetBackup Flex Scale appliance does not support communication between a pure IPv6 and a pure IPv4 address configuration. A NetBackup Flex Scale cluster with an all IPv6 address configuration cannot communicate with a system that is assigned an IPv4 address. The system must be configured either using a pure IPv6 address or using a pure IPv4 address network configuration.

A system in this context refers to a host that NetBackup uses to authenticate and then discover the workloads that need to be protected. For example, if you wish to protect VMware virtual machines, then the VMware vCenter Server or the VMware ESXi server that you add to NetBackup must be configured either to use a pure IPv6 address or use a mixed mode dual stack IP address configuration for communicating over an IP network.
