Access the Symmetrix CLI: Log into the Symmetrix Command Line Interface (CLI) on the system where the VMAX LUNs are provisioned.

Run the Command: Execute the symdev -sid list -rp_tag command to list all devices with the RecoverPoint tag.

Verify Tagging: Review the output to confirm that the VMAX LUNs intended for use with RecoverPoint are correctly tagged.

This command is part of the EMC Symmetrix CLI and is specifically used to verify the tagging of LUNs for RecoverPoint, ensuring that they are recognized by the RecoverPoint system for replication purposes1.

Access the Cluster Management Interface: Use a web browser to navigate to the RecoverPoint Cluster Management IP address.

Navigate to the Load Statistics: Append /info/long_term_statistics to the Cluster Management IP in the browser's address bar.

View the Report: The RecoverPoint Cluster Load report can be viewed on this page, which provides long-term statistics including load information.

This method allows administrators to retrieve historical load data even if they did not capture the output at the time the capture load command was run1.

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.

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.

Understanding RPA Addition: Adding a new RPA node to an existing RecoverPoint cluster is a common task to enhance the system's capacity and performance. The process is designed to be non-disruptive to ensure continuous replication and data protection.

Non-Disruptive Addition:

Step 1: Use the Deployment Manager's ''Add RPA'' wizard. This tool automates the process of adding a new RPA to the cluster without interrupting ongoing replication1.

Step 2: Follow the wizard's instructions to connect the new RPA to the existing cluster. This includes configuring network settings, updating the cluster configuration, and ensuring that the new RPA is properly integrated.

Verification:

Step 3: After adding the new RPA, verify that it is correctly recognized by the RecoverPoint system. Check the status of the new RPA in the RecoverPoint Management Application.

Step 4: Ensure that the existing Consistency Groups and replication processes are functioning as expected. There should be no interruption or need for reconfiguration of the Consistency Groups1.

Monitoring:

Step 5: Monitor the system to ensure that the new RPA is performing correctly and that there are no issues with replication. Use the management tools to check the health and performance of the entire cluster.
