Delete Inbound Replica Collection Sets, Replica Collections, or Replicas
You can delete an inbound volume replica collection, an inbound replica that is part of a replica collection, or the entire inbound replica
collection set for a volume collection. Deleting a replica collection deletes all the replicas that are in the collection.
The following considerations apply:
• Dell recommends that you delete replicas when you are logged in to the primary group.
• Deleting a replica collection set disables replication on the volume collection.
• To delete the most recent replica, you must disable replication for the volume or collection.
1. Click Replication and expand the partner name.
2. Expand Volume Replication.
3. Click Inbound Replica Collections.
4. Click Pause inbound if you are deleting an inbound replica collection set. When prompted, click Yes to conrm the operation.
5. Delete items as follows:
• To delete a replica collection set, select the replica set and click Delete replica collection set.
• To delete multiple replica collections, select a replica collection set and click Delete Replica Collections. When the dialog
box opens, hold down the Control key while selecting replica collections and then click OK.
• To delete a single replica collection, expand the replica collection set, select the replica collection, and click Delete replica
collection.
• To delete an individual replica, expand the replica collection, select the replica, and click Delete replica.
6. In the Activities panel, click Resume inbound to resume inbound replication.
The replica, replica collection, or replica collection set no longer appears in the group. However, the replica or replica set still appears
on the partner (primary group), if it is available. You can log in to the primary group and delete the replica or replica set.
About Replication Borrowing
Replication borrowing allows you to temporarily increase the available replication space for a volume by borrowing space from other
sources. By allowing replicas to borrow beyond their congured reserve, this available space is utilized more eciently and the max-
keep policy is maintained.
Keep the following considerations about replication borrowing in mind:
• All members in a group must be running PS Series rmware version 8.0 or later. Replication borrowing does not work in
environments running mixed versions of the rmware.
• Replication borrowing is always enabled and happens automatically.
Example of Replication Borrowing
Replication requires a replica reserve that is suciently large enough to hold all of the replicas that you want to keep. For a volume
that is scheduled to replicate once per day with a max-keep of 3, if the replica reserve is set too high, a lot of space will not be used.
This underutilization of space might lead you to reduce the reserve to hold only three days of replication data.
