In a Dell RecoverPoint environment, Direct Access mode allows for write access to a replica volume during testing or other scenarios. However, when using XtremIO arrays, Direct Access mode is not available because XtremIO handles replication differently compared to other array types.Instead, XtremIO uses its snapshot technology, which does not support Direct Access in the same way as traditional replication methods1.

Here’s why Direct Access is limited with XtremIO:

XtremIO Snapshot Technology: XtremIO arrays use snapshot technology for replication, which is different from the replication methods used by other array types like VMAX, VNX, or VPLEX.

Direct Access Mode: This mode typically allows a replica volume to be mounted and written to directly, but due to the way XtremIO handles snapshots, this functionality is not supported.

RecoverPoint Integration: RecoverPoint integrates with XtremIO to provide replication and disaster recovery solutions, but the Direct Access feature is not compatible with XtremIO’s snapshot-based replication1.

Therefore, when using XtremIO arrays in a RecoverPoint environment, administrators need to be aware of this limitation and plan their disaster recovery and testing strategies accordingly1.

When initializing a Consistency Group with a local copy in a RecoverPoint environment, several factors can affect the duration of the process. One possible reason for a longer than expected initialization time is slow performing storage on the production array.If the production storage is not able to handle the I/O operations efficiently, it can lead to delays in the initialization process1.

Another factor to consider is the available bandwidth to the RecoverPoint Appliances (RPAs).Limited WAN bandwidth can also cause delays, but since the scenario mentions a local copy, WAN bandwidth is less likely to be the issue unless the RPAs are also handling remote replication1.

Size mismatch between the production and copy volumes or the copy not being attached to the same splitter as production could also be potential issues, but these would typically prevent initialization from proceeding rather than causing a delay1.

For a detailed diagnosis and resolution, it is recommended to review the system’s performance metrics and logs, and consult the official Dell RecoverPoint documentation or contact Dell EMC support directly1.

The Dell RecoverPoint documentation recommends a wait period of 7 days before running the Balance Load tool. This period allows for the system to stabilize and for any anomalies in the load distribution to become apparent, ensuring that the Balance Load tool can operate effectively. It’s important to note that this information is based on the best practices outlined in the Dell RecoverPoint documentation and may be subject to change with different versions or specific system configurations.For the most accurate and up-to-date information, it is always best to consult the latest official Dell RecoverPoint documentation or contact Dell EMC support directly1.

To meet the requirement of keeping a local copy of the production data in a RecoverPoint environment with VNX(SE) clusters, the administrator can add a local copy into the existing Consistency Group. This action does not require deleting and reconfiguring the existing Consistency Group or upgrading the license. Here are the steps:

Access Unisphere for RecoverPoint: Log into the Unisphere interface for RecoverPoint management.

Navigate to the Consistency Group: Find the Consistency Group that needs the local copy.

Add a Local Copy: Use the option to add a copy into the selected Consistency Group.

Configure the Local Copy: Specify the settings for the local copy, such as the Journal volume and RPO settings.

Apply Changes: Save the changes to implement the local replication.

This process allows the administrator to enhance the data protection strategy by adding a local copy for operational recovery or other business needs without disrupting the existing remote replication setup1.
