Alternatively, you can unregister the newly registered Prism Element and register it to another Prism Central in an Availability Zone pair with the Prism Central of the Remote File Server. If you have any issues, please refer to KB article 14865.ImpactThe remote file server is not visible on the local Prism Central. This means that the data protection policy cannot be managed appropriately. Also, DR workflow cannot be accomplished.Alert IDA160180 Alert TitleRemote file server of data protection policy is registered to a Prism Central which is not in an Availability Zone pairAlert MessageRemote file server {remote_fs_name} for data protection policy {policy_uuid} with file server {fs_name} is registered to Prism Central {remote_pc_name} ({remote_pc_uuid}), which is not in an Availability Zone pair with the local Prism Central
 . Resolving the issueThis alert ensures that Availability Zones are maintained through File Server Migrations. If a File Server, or a File Server Remote DR site, moves to a new Prism Central instance, and the new Prism Central is not included in the Availability Zones, this alert will trigger. Add an Availability Zone pair between local Prism Central and Prism Central of the remote file server. Alternatively, you can unregister the newly registered Prism Element and register it to another Prism Central in an Availability Zone pair with the Prism Central of the Remote File Server.  For information about Availability Zones and their management, refer to the Nutanix Disaster Recovery Guide.
