The correct sequence of steps for Snap-based replication on XtremIO is:

Create the snapshot

Get the DIFF between the snapshot and the root volume

Create a second snap, and then retrieve the DIFF between the first and second snapshot

Transfer the DIFF

Create and promote the snapshot

Snap-based replication on XtremIO involves the following steps:

Create the snapshot: This step involves taking a snapshot of the source volume that will be used as

the baseline for replication.

Get the DIFF between the snapshot and the root volume: Here, the differences between the

snapshot and the root volume are calculated. This is necessary to understand what changes have

been made since the last snapshot.

Create a second snap, and then retrieve the DIFF between the first and second snapshot: A second

snapshot is created to capture the latest state of the volume. The differences (DIFF) between the first

snapshot and the second snapshot are then calculated.

Transfer the DIFF: The differences identified between the snapshots are transferred to the target

volume. This ensures that only the changes are replicated, optimizing the replication process.

Create and promote the snapshot: Finally, the snapshot is created and promoted to ensure the target

volume is updated with the latest changes.

This sequence ensures efficient and accurate replication by focusing on the changes between

snapshots, rather than replicating the entire volume each time.

Access the RecoverPoint CLI: The rp_import-certificate command is issued within the RecoverPoint

Command Line Interface (CLI).

Purpose of the Command: This command is used to update or import certificates into the

RecoverPoint system. It is particularly relevant when certificates have been changed to a self-signed

or CA-signed certificate, rather than a default one1.

Execution of the Command: To execute the command, you would typically need to be logged in as a

user with appropriate permissions, such as the root or security-admin user.

The rp_import-certificate command is an essential part of maintaining the security of the

RecoverPoint system by ensuring that the certificates used for secure communications are up to

date1.

When changing from physical RPAs to vRPAs in a RecoverPoint with VNX(SE) environment, the

licensing remains the same and no additional action is required. The existing licenses can be applied

to the virtual RPAs without the need for new licenses.

MetroPoint Consistency Group is designed to contain both active and standby production copies.

It integrates VPLEX Metro with RecoverPoint, providing a 3-site solution that allows for continuous

availability and operational recovery1.

A single Consistency Group is configured which contains the two Production copies (active and

standby) and a Replica Copy1.

This setup ensures that both VPLEX clusters’ data are protected and continuously available, with the

ability to failover between two Metro sites without impacting protection1.

For more detailed information, you can refer to Dell’s official documentation on MetroPoint, which

explains the functionalities and configurations of MetroPoint Consistency Groups12.

When configuring zoning for RecoverPoint with VNX(SE), it is essential to follow the best practices

and guidelines provided by Dell.

The zoning configuration typically involves manual setup to ensure that the RPA ports and VNX Front

End (FE) ports are correctly zoned to allow for proper communication and replication processes1.

The manual method allows for precise control over the zoning configuration, which is crucial for the

RecoverPoint system’s performance and reliability1.

While automatic zoning might be available in some environments, the recommended and supported

method for RecoverPoint with VNX(SE) is manual zoning, as it provides the necessary customization

and adherence to best practices1.

For the most accurate and detailed instructions, always refer to the latest official documentation or

contact Dell EMC support directly. The information provided here is based on general knowledge of

RecoverPoint systems and may not reflect the most recent updates or specific configurations.
