PowerProtect Data Manager 19.15 Microsoft SQL Server User Guide

Changing the preferred host address

You can change the preferred host address that is used for communication between PowerProtect Data Manager and the application-agent host.

If the Microsoft application agent is configured to use the Application Direct data path, the preferred host address can be an IPv4 address, an IPv6 address, or a fully qualified domain name (FQDN).

NOTE:Using an FQDN is only available as of version 19.14 of the application agent.

It is recommended to use an FQDN as the preferred host address in DHCP environments and other environments where static IP addresses can change. When DHCP is used instead of an IP address and the IP address of the host changes, the following benefits occur:

  • Communication between PowerProtect Data Manager and the host is uninterrupted.
  • Backup and restore operations succeed.
  • Reregistration of the application agent is not required.

If the Microsoft application agent is configured to use the VM Direct data path, the use of an FQDN is unsupported, and the preferred host address can only be an IPv4 address or an IPv6 address.
