PowerProtect Data Manager Appliance 5.15.0.0 Administrator's Guide for DM5500

The encryption settings on both the source and destination systems must match to ensure successful replication. If there is an Encryption mismatch and the source DD is less than 7.10 version, then any replication target is not available in the UI. Also, if source target and replication target are 7.10 or greater, then MFR automatically chooses the most secure setting based on the current encryption settings on source and destination DD respectively.

For example, if you enable in-flight encryption in PowerProtect Data Manager Appliance, the setting must be enabled on each source and destination server before defining the PowerProtect Data Manager Appliance replication objective. If encryption is enabled after the initial definition of replication objectives, any replication jobs that were initiated during the period when the source and destination server encryption settings did not match will fail.

If replication encryption mode is changed on a replication PowerProtect Data Manager Appliance, it may take up to 1 hour for the source appliance to discover this change. To detect the change immediately, initiate manual discovery on the replication target from Infrastructure > Storage > Replication Target. This may be necessary when updating a replication policy after configuration changes since the source and destination appliance must have the same replication encryption setting.

The Infrastructure > Storage window of the PowerProtect Data Manager Appliance UI displays the status of the in-flight encryption setting for all attached storage systems.
