To increase data protection by converting a local RAID-0 virtual volume to a distributed virtual volume, the recommended method is to create a corresponding device on the remote cluster and then attach it as a mirror to the existing local device. This process effectively creates a distributed virtual volume that spans across both clusters.

Create a Device on the Remote Cluster: Start by creating a new device on the remote VPLEX cluster. This device should be of the same size as the local RAID-0 virtual volume and should not have a virtual volume associated with it1.

Attach as a Mirror: Once the remote device is created, attach it as a mirror to the local RAID-0 virtual volume. This operation is performed using the VPLEX CLI and will begin the process of mirroring the data from the local device to the remote device1.

Synchronization: After attaching the remote device as a mirror, the VPLEX system will synchronize the data between the local and remote devices. This ensures that both devices have identical data and are in a consistent state1.

Distributed Virtual Volume: Once the synchronization is complete, the local and remote devices together form a distributed virtual volume. This volume now has increased data protection because it is distributed across two different clusters1.

Verification: Verify that the distributed virtual volume is functioning correctly by checking its status and ensuring that it is accessible from both clusters1.

Best Practices: It is important to follow the best practices for creating and managing distributed virtual volumes as outlined in the Dell VPLEX Deploy Achievement documents. This includes proper planning, execution, and verification of the mirroring process1.

In summary, the recommended method to change a local RAID-0 virtual volume to a distributed virtual volume is to create a corresponding device on the remote cluster and attach it as a mirror, thereby forming a distributed virtual volume with increased data protection.

When using VPLEX with RecoverPoint enabled consistency groups, it is important to ensure that local copy volumes and production volumes are placed in separate consistency groups. This separation is crucial for maintaining the integrity of the data replication and recovery processes.

Consistency Group Configuration: Consistency groups in VPLEX are logical groupings of virtual volumes that VPLEX treats as a single unit for operations such as data mobility and recovery. When RecoverPoint is enabled, these groups also align with RecoverPoint consistency groups for replication purposes1.

Separation of Volumes: Keeping local copy volumes (volumes used for local replication) and production volumes (active volumes serving data to hosts) in separate consistency groups helps to prevent any potential conflicts or issues with replication and ensures that the local copies are consistent and usable for recovery1.

RecoverPoint Replication: RecoverPoint provides continuous data protection and replication for recovery to any point in time. The separation of volumes into different consistency groups helps to manage and maintain the replication process effectively1.

Operational Management: By separating these volumes into different consistency groups, administrators can manage operations such as replication, failover, and recovery with greater precision and control1.

Best Practices: This separation is part of the best practices recommended by Dell EMC when configuring VPLEX with RecoverPoint, ensuring that the system operates efficiently and that data is protected in case of any failures1.

In summary, when using VPLEX with RecoverPoint enabled consistency groups, local copy volumes and production volumes must be placed in separate consistency groups to ensure proper replication and recovery processes.

Upgrading a VPLEX from VS2 to VS6 hardware involves several critical requirements to ensure a successful and non-disruptive process:

GeoSynchrony Version: The system must be running at least GeoSynchrony 6.0. This is the software that orchestrates operations across the VPLEX infrastructure and ensures compatibility between different hardware generations1.

Code Level Consistency: Both the VS2 and VS6 platforms must be operating at the same software code level. This uniformity is crucial to prevent any incompatibility issues during the upgrade process1.

Engine Count: The number of engines in the existing VS2 setup must match the number of engines in the VS6 configuration. This alignment is necessary to maintain performance and capacity expectations post-upgrade1.

WWN Zoning: Proper WWN (World Wide Name) zoning must be in place. WWN zoning is a method of isolating network traffic to ensure that devices within a Fibre Channel network can only communicate with each other if they are in the same zone1.

Upgrade Process: The upgrade process typically involves replacing the VS2 hardware with VS6 components. This hardware swap should be done in a manner that does not disrupt the ongoing operations and services1.

Post-Upgrade Verification: After the hardware upgrade, it’s essential to verify that all systems are functioning correctly. This includes checking the status of the front-end and back-end ports, as well as the health of the virtual volumes1.

Documentation and Support: Detailed procedures for the upgrade process can be found in the SolVe Desktop Procedure Generator, which provides step-by-step instructions for upgrading cluster hardware from VS2 to VS61.

In summary, the requirements for upgrading a VPLEX from VS2 to VS6 include running GeoSynchrony 6.0 or higher, ensuring both platforms are at the same code level, matching the number of engines, and having proper WWN zoning in place.
