D-RP-OE-A-24 Exam Dumps : Dell RecoverPoint Operate Achievement

The Dell EMC RecoverPoint Gen6 appliance contains two slots for I/O modules. For Slot1, the supported I/O modules are 10-Gb optical fiber and 10-Gb twisted copper pair.This means that Slot1 can accommodate either 10 GbE optical or 10 GbE copper I/O modules1.

The I/O modules are network interface cards with the following characteristics:

10-GB OPTICAL FIBER MODULE: 4 ports, Ethernet network type, supported speed of 10 Gb, wire type of optical fiber (SFP+).

10-GB TWISTED COPPER PAIR MODULE: 4 ports, Ethernet network type, supported speed of 10 Gb, wire type of BASE-T twisted copper pair1.

These modules provide the necessary connectivity for the RecoverPoint appliance to manage replication setup and operations, ensuring efficient data protection and disaster recovery capabilities1.

In a Dell RecoverPoint environment, Journal volumes are critical components used to track and manage point-in-time images for data replication and recovery. If Journal volumes are mistakenly masked to hosts, the following occurs:

Hosts Gain Access: The hosts that are zoned/masked to the Journal volumes gain the ability to write to these volumes.

Potential for Corruption: Any write access by hosts to the Journal volumes can lead to corruption of the Journal. This is because Journals are meant to be managed exclusively by RecoverPoint and should not be directly accessed or modified by hosts.

Impact on Replication: Journal corruption can disrupt the RecoverPoint replication process, potentially leading to data loss or an inability to recover to specific points in time.

Resolution: To prevent such issues, it is crucial to ensure that Journal volumes are not exposed to hosts and are only accessed by RecoverPoint Appliances (RPAs) for replication purposes12.

It is important to follow best practices for zoning and masking in a storage environment to avoid such critical configuration errors12.

When a Consistency Group failover is performed to a remote copy in a Dell RecoverPoint system, the point-in-time images stored in the copy Journal are deleted after the copy becomes the new production.This is because the copy Journal’s role is to maintain a record of changes for recovery purposes, and once the copy is promoted to production, its Journal is reset to start recording new changes from that point forward1.

The process involves the following steps:

Failover Initiated: The administrator initiates a failover to the remote copy.

Copy Becomes Production: The remote copy is promoted to the production role.

Journal Reset: The point-in-time images in the copy Journal are deleted as part of the promotion process.

New Production Journal: A new production Journal is started to record changes from the new production copy moving forward.

This ensures that the RecoverPoint system can continue to protect the data with a fresh start for the new production environment1.
