Dell PowerVault ME4 Series Storage System Administrator’s Guide

Creating a replication set from the Volumes topic

You can create a replication set, which specifies the components of a replication. The Create Replication Set panel enables you to create replication sets. You can access this panel from both the Replications and Volumes topics.

Performing this action creates the replication set and the infrastructure for the replication set. For a selected volume, snapshot, or volume group, the action creates a secondary volume or volume group and the internal snapshots required to support replications. By default, the secondary volume or volume group and infrastructure are created in the pool corresponding to the one for the primary volume or volume group (A or B). Optionally, you can select the other pool.

A peer connection must be defined to create and use a replication set. A replication set can specify only one peer connection and pool. When creating a replication set, communication between the peer connection systems must be operational during the entire process.

If a volume group is part of a replication set, volumes cannot be added to or deleted from the volume group.

If a replication set is deleted, the internal snapshots created by the system for replication are also deleted. After the replication set is deleted, the primary and secondary volumes can be used like any other base volumes or volume groups.
