When connecting RecoverPoint clusters over IP, it is crucial that the network infrastructure supports the data transmission requirements of RecoverPoint.

Jumbo frames are larger than standard Ethernet frames and can carry more data, reducing overhead and improving performance1.

If jumbo frames are not enabled on the IP network, the RecoverPoint clusters may fail to connect due to the inability to handle the larger data packets required for efficient replication and synchronization2.

The MTU (Maximum Transmission Unit) size also plays a role in this process.An MTU size of 9000 is often recommended for jumbo frames, but if the network devices do not support this configuration, it can lead to connection issues2.

It’s important to ensure that all network devices along the path support jumbo frames and are configured correctly to allow for the larger MTU size required by RecoverPoint clusters1.

For detailed troubleshooting steps and to confirm the exact cause of the connection failure, refer to the Dell RecoverPoint documentation or contact Dell EMC support for assistance. The information provided here is based on general knowledge of networking requirements for RecoverPoint systems and may not reflect the most recent updates or specific configurations.

Physical Connection: The RPAs should be physically connected to each other using their iSCSI ports.This is because the host systems are configured with iSCSI HBAs, which indicates that the storage network is based on iSCSI protocol1.

Configuration in RecoverPoint: In the RecoverPoint Deployment Manager, ensure that the iSCSI ports of the RPAs are correctly configured to communicate with the VNX array.

Verification: After the physical connections and configurations are made, verify that the RPAs can communicate with the VNX array and that the iSCSI connections are stable and operational.

It is important to note that while the RPAs are connected through their iSCSI ports, they should not be connected to any MirrorView ports on the VNX array.Additionally, ensure that the RPAs are connected directly to the FC ports on the Storage Processors (SPs) and not to an expansion SFP on the file side1.

The correct sequence of steps to implement RecoverPoint with VPLEX is:

Zone the RPA FC ports to the VPLEX cluster VPLEX BE and FE ports

Register the RPA initiators with VPLEX and then create a storage view (masking)

Import the certificates and add the RecoverPoint cluster to VPLEX

Register the VPLEX credentials in RecoverPoint

License VPLEX with RecoverPoint

Explanation:When integrating RecoverPoint with VPLEX, it is essential to follow these steps in the correct order. Begin by zoning the RPA FC ports to both the BE (Back-End) and FE (Front-End) ports of the VPLEX cluster. Then, register the RPA initiators with VPLEX and create a storage view (masking). Next, import the necessary certificates and add the RecoverPoint cluster to VPLEX. Register the VPLEX credentials in RecoverPoint, and finally, license the VPLEX with RecoverPoint to complete the setup.

The snapshots that represent the point-in-time images during normal replication are kept:

C. In the Journal pool on the XtremIO array containing the production volume

Explanation:In a RecoverPoint system, the Journal volumes are used to store the snapshots that represent the point-in-time images of the data being replicated. When both the production and copy volumes are provisioned from XtremIO arrays, the Journal pool on the XtremIO array containing the production volume is utilized to store these snapshots during normal replication.

Initiator Type - RecoverPoint Appliance: When registering each RPA initiator with the VNX, it is essential to specify the initiator type as “RecoverPoint Appliance” to ensure proper identification and compatibility within the storage network.

Failover Mode - 4 (ALUA): The failover mode should be set to 4, which corresponds to Asymmetric Logical Unit Access (ALUA).This mode allows for optimized path failover and is the recommended setting for RecoverPoint appliances1.

For more detailed information and guidance on the configuration process, refer to the documentation provided by Dell, such as the RecoverPoint Deploying VNX and CLARiiON Arrays and Splitter Technical Note, which outlines the necessary steps for proper RPA initiator registration and configuration1.

Accessing the RPA: To retrieve the WWNs / PWWNs, you need to log into each RecoverPoint Appliance (RPA) individually.

Step 1: Use an SSH client to connect to the RPA.

Step 2: Log in with the boxmgmt user credentials.

Navigating to SAN Diagnostics: Once logged in, navigate to the SAN Diagnostics menu.

Step 3: From the main menu, select the option for SAN Diagnostics. This menu provides various diagnostic tools and information related to the SAN environment.

Retrieving WWNs / PWWNs: Within the SAN Diagnostics menu, you can retrieve the WWNs / PWWNs.

Step 4: Select the option to display the initiators. This will list the WWNs / PWWNs associated with the RPA.

Verification: Ensure that the retrieved WWNs / PWWNs are correct and correspond to the intended RPAs. This information is crucial for configuring zoning on the Brocade switch.

References: This process is verified based on the official Dell RecoverPoint documentation, which outlines the steps for accessing and retrieving WWNs / PWWNs from the RPAs12.

Install the new RecoverPoint/EX cluster: Begin by deploying the new RecoverPoint/EX cluster at the new data center. This involves setting up the physical or virtual appliances that will form the new cluster.

Add the license to the new cluster: Once the new cluster is installed, the next step is to add the appropriate licenses. This is crucial as it enables the new cluster’s functionality within the RecoverPoint environment.

Connect the new cluster to the existing system: After the licensing is in place, the new cluster needs to be connected to the existing RecoverPoint system. This includes configuring the communication between the new and existing clusters to ensure proper replication and synchronization.

For detailed guidance on these steps, the RecoverPoint Deployment Manager can be used.It provides a suite of wizards that assist with various operations, including modifying cluster settings and adding new clusters to an existing system1.Always ensure to use the latest version of the Deployment Manager and follow the instructions provided within the tool for a non-disruptive setup1.

It is also recommended to consult the Dell RecoverPoint for Virtual Machines Installation and Deployment Guide for comprehensive instructions and best practices2.Additionally, for automation and scripting of deployment tasks, including adding new clusters, refer to the documentation on RecoverPoint for VMs Deployment Automation3.

=========================

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.

Understanding Group Sets: Group Sets in Dell RecoverPoint allow administrators to create a consistent point-in-time image across multiple Consistency Groups. This is particularly useful in environments where data consistency across different applications or databases is critical.

Functionality: When using Group Sets, a single bookmark can be applied to multiple Consistency Groups simultaneously. This ensures that all the groups are synchronized to the same point in time, providing a consistent recovery point across different data sets.

Implementation:

Step 1: Access the RecoverPoint Management Application.

Step 2: Navigate to the Group Sets section.

Step 3: Create a new Group Set and select the Consistency Groups that need to be included.

Step 4: Apply a bookmark to the Group Set. This action will create a consistent point-in-time image across all selected Consistency Groups.

Verification: After setting up the Group Set and applying the bookmark, verify that the point-in-time image is consistent across all included Consistency Groups. This can be done by checking the bookmarks and ensuring they are synchronized.

References: This information is verified based on the official Dell RecoverPoint documentation, which details the use and configuration of Group Sets for achieving consistent point-in-time images across multiple Consistency Groups12.

Deployment Manager Overview: The Deployment Manager is a tool used to install and configure RecoverPoint clusters. It guides users through various steps to ensure the proper setup and configuration of the system.

Prepare New Cluster for Connection: During this step, the Deployment Manager prepares the new cluster for connection to the existing infrastructure. This involves several sub-steps, including network configuration, validation of the environment, and ensuring that all necessary components are in place.

Adding Licenses: As part of the “Prepare New Cluster for Connection” step, new RecoverPoint licenses are added to the cluster. This is crucial because the licenses enable the functionality of the RecoverPoint system, allowing it to perform replication and recovery tasks.

Verification: After adding the licenses, the Deployment Manager verifies that the licenses are correctly applied and that the cluster is ready for the next steps in the deployment process.
