This operation enables you to add a remote replication pair into a consistency group. This ensures that the secondary resource data of the new pair and that of other pairs in the consistency group are consistent in time.
Prerequisites
- Replication Mode of the remote replication pair to be added to a consistency group is the same as that of the consistency group.
- Role of the consistency group to which the remote replication pair is to be added is Primary.
- Role of the remote replication pair to be added to a consistency group is Primary.
- The number of remote replication pairs in a consistency group has not reached the upper limit.
Precautions
- If a consistency group is in split status, when a remote replication pair is added, the system will split the remote replication pair first and then add it into the consistency group.
- If a consistency group is not in split status, when a remote replication pair is added, the system will split the consistency group first, then split the remote replication pair, add it into the group, and synchronize the consistency group.
Procedure
- Choose Data Protection > Block Protection > Remote Replication Consistency Group.
- Click More on the right of the desired remote replication consistency group and select Add Remote Replication Pair.
The Add Remote Replication Pair page is displayed on the right.
- In the Available Remote Replication Pairs area on the left, select one or more remote replication pairs and click
to add them to the Selected Remote Replication Pairs area on the right. - Click OK.
