PowerProtect Data Manager Appliance 5.15.0.0 Microsoft SQL Server User Guide

Communication with components

If PowerProtect Data Manager Appliance is configured to only use one protocol, all components it communicates with must also use that protocol.

Network-attached storage and internal protection storage, storage units

If the storage unit of a protection policy is different or changed from the destination asset source, you must assign a network to the destination asset for a successful restore. For example, if your source asset is backed up in an IPv4 network, you must assign an IPv4 network to the destination asset for the restore to be successful.

To assign a network for the destination asset, perform the following steps:

1. In the PowerProtect Data Manager Appliance UI, select Infrastructure > Assets > NAS.
2. Select the destination asset, click More Actions and select Assign Network. The Assign Network page appears.
3. Select a network from the Network Label list, click Save.
4. If a restore failed because of the wrong destination address, retry the operation.

Name resolution

Name resolution and reverse IP lookup must be configured to ensure the following:

• Fully qualified domain names of PowerProtect Data Manager Applianceand its components resolve to a valid IPv4 address.
• All IPv4 addresses are valid and reachable.
• The FQDNs of application-agent hosts that use FQDN as their preferred host address resolve to a valid IPv4 address.
• Each application-agent host that uses FQDN as its preferred host address resolves the FQDN of PowerProtect Data Manager Appliance to an IP address of the same protocol that it uses. For example, if a host uses IPv4, it resolves the FQDN of PowerProtect Data Manager Appliance to an IPv4 address.
