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.

When the "Collect System Information" button is clicked, it initiates a log collection process that covers 2 hours before and 2 hours after the selected event. This ensures a comprehensive log collection around the time of the event, which is crucial for effective troubleshooting and analysis.

Zoning: All RecoverPoint Appliance (RPA) Fibre Channel (FC) ports must be zoned to the same Front-End (FA) ports as the hosts.This is to ensure that the RPAs can see the LUNs and perform the necessary operations1.

LUN Masking: After zoning, LUN masking must be configured to expose the LUNs to both the hosts and the RPAs through the same FA ports.This involves setting up the initiator group, port group, and storage group correctly1.

For detailed instructions on zoning and LUN masking with VMAX splitters, it is recommended to refer to the RecoverPoint Deploying with Symmetrix Arrays Technical Notes document, which provides comprehensive guidelines for these configurations1.

In the write phase of RecoverPoint replication, the write splitter intercepts write data from the production host and sends it to the RecoverPoint Appliance (RPA).

The RPA then immediately acknowledges receipt of the write data to the write splitter1.

This acknowledgement occurs as soon as the RPA receives the write, which is before the distribution phase or any acknowledgements from other copies involved in the replication process1.

The prompt acknowledgement allows the write splitter to continue processing other writes, ensuring efficient replication and system performance1.

For detailed information on the write phase and the role of the RPA and write splitter in RecoverPoint replication, it is advisable to consult the official Dell RecoverPoint documentation or contact Dell EMC support.

Verify Write Splitter: Before running the Deployment Manager for a RecoverPoint with Unity installation, ensure that the Unity RecoverPoint write splitter is enabled1.

Check Licensing: Although not mentioned in the question, it’s also important to verify that the correct licensing is in place for RecoverPoint with Unity1.

Run Deployment Manager: Once the write splitter is confirmed to be enabled, proceed with running the Deployment Manager, RecoverPoint with Unity Installer wizard1.

The write splitter is a crucial component that allows RecoverPoint to intercept write I/Os and replicate them to the remote site.Ensuring it is enabled is a necessary step before deployment1.

In order to perform dynamic resizing of a replication set, the requirement is:

B. Both production and the copies must be provisioned from an XtremIO array

Explanation:Dynamic resizing of a replication set requires both the production and replica copies to be provisioned from an XtremIO array. XtremIO's architecture supports this dynamic resizing capability, allowing administrators to adjust the size of the replication set without interrupting ongoing operations.

Access the CLI: Use the boxmgmt account to log into the Command Line Interface (CLI) of the RecoverPoint Appliance.

Run the Command: Execute the set_user name=admin password= command to initiate the password reset process.

Set New Password: Follow the prompts to set a new password for the admin user.

This process is used when the admin password has been lost and needs to be reset.It is important to follow the correct syntax and procedure to ensure the security and integrity of the system1.
