Dell 34XX, 38XX Disabling The Remote Replication Legacy Premium Feature, Snapshot Virtual Disks

CAUTION: Possible loss of data access – Deleting a primary virtual disk or a secondary virtual disk permanently removes the data from the storage array.

Disabling The Remote Replication (Legacy) Premium Feature

You disable the Remote Replication (legacy) premium feature to prevent the new replication relationship from being created. When you disable the Remote Replication (legacy) premium feature, the premium feature is in a Disabled/Active state. In this state, you can maintain and manage previously existing replication relationships; however, you cannot create new relationships. To disable the Remote Replication (legacy) premium feature, use this command:

disable storageArray feature=remoteReplication

Deactivating The Remote Replication (Legacy) Premium Feature

If you no longer require the Remote Replication (legacy) premium feature and you have removed all of the replication relationships, you can deactivate the premium feature. Deactivating the premium feature re-establishes the normal use of dedicated ports on both storage arrays and deletes both replication repository virtual disks. To deactivate the Remote Replication (legacy) premium feature, use this command:

deactivate storageArray feature=remoteReplication

Interaction With Other Premium Features

You can run the Remote Replication (legacy) premium feature while running these premium features:

•Snapshot—both standard Snapshot and Snapshot (legacy) premium features

•Virtual Disk Copy

When you run the Remote Replication (legacy) premium feature with other premium features, you must consider the requirements of the other premium features to ensure that you set up a stable storage array configuration.

In addition to running with the premium features, you can also run the Remote Replication (legacy) premium feature while running Storage Partitioning and Virtual Disk Expansion (VDE).

Snapshot Virtual Disks

A snapshot virtual disk is a point-in-time image of a virtual disk. It is typically created so that an application, such as a backup, can access the snapshot virtual disk and read the data while the source virtual disk remains online and accessible to hosts.

CAUTION: Before using the source virtual disk of a snapshot virtual disk as your target, you must disable all snapshot virtual disks associated with the source virtual disk. By disabling the snapshot virtual disks, you avoid altering the snapshot data if the source virtual disk is changed.

Creating a snapshot virtual disk automatically creates a snapshot repository virtual disk. The snapshot repository virtual disk stores information about the data that has changed since the snapshot virtual disk
