Power On: Ensure that RPA-3 is powered on.

Configure LAN Address: Assign and configure the LAN IP address as displayed in the wizard for RPA-3.

Verification: Verify that the RPA-3 is reachable at the configured LAN address.

Advance the Wizard: Once the above steps are confirmed, select ''Next'' to proceed with the wizard.

Create a Consistency Group for the application: The first step is to create a Consistency Group (CG) in the RecoverPoint system for the mission-critical application. This CG will manage the replication and ensure consistency across the volumes.

Determine the number of replication sets: Each volume provisioned from the VNX for the application will be represented as a separate replication set within the CG. Since there are three volumes, there will be three replication sets.

Configure replication sets: Each replication set will include the production volume (source) and the replica volume (target). The replication sets will be managed under the same CG to maintain consistency across all the application data.

For more detailed information, you can refer to the Dell EMC RecoverPoint documentation, which provides guidelines on how to configure replication sets within a CG. It is also advisable to consult the RecoverPoint Deployment Manager for step-by-step instructions on setting up and managing CGs and replication sets1.

Snapshot Writes: When application testing is performed on a remote copy, writes are directed to an XtremIO snapshot. This snapshot is a point-in-time image of the data.

Journal Behavior: These writes do not advance the Image Access log capacity because the snapshot operates independently of the Journal. The Journal is used for logging changes to the production data, not the snapshot data1.

Static Image Access Log: As a result, the Image Access log capacity remains static during the testing of the remote copy, as it is not affected by the writes to the snapshot1.

It's important to understand that the Image Access log is designed to track changes to the replicated data in real-time. However, when operating on a snapshot, these changes are not logged in the same way, hence the Image Access log capacity does not change1.

Initiator Identification: Unisphere identifies a RecoverPoint initiator with VNX through RPA registration by using the World Wide Name (WWN) of the RecoverPoint Appliance (RPA).

Registration Process: During the registration process, the RPA's WWN is used to uniquely identify and authenticate the RPA within the storage network.

Unisphere Integration: Once registered, the RPA can be managed and monitored through Unisphere, which is the management interface for VNX and other EMC storage systems.

For detailed procedures on RPA registration and integration with Unisphere, refer to the Dell RecoverPoint deployment documentation or the Unisphere for RecoverPoint user guide12.

Check RPA Versions: Verify the software versions on all RPAs to ensure they are running the same version of RecoverPoint.

Update RPA Version: If any RPA is running a different version, update it to match the version running on the other RPAs.

Retry Installation: Once all RPAs are running the same version, retry the failed step in the Deployment Manager Installer1.

It is crucial for the proper functioning of the RecoverPoint cluster that all RPAs run the same version of the software. Discrepancies in versions can lead to issues during installation and operation1.
