Congure a Volume Collection for Replication
You can simultaneously replicate data in related volumes by replicating the volume collection. The resulting set of replicas is called a
replica collection.
NOTE: To replicate a volume collection, you must congure all the volumes in the collection to replicate to the same
partner.
1. Click Volumes.
2. Expand Volume Collections and then select the collection that you want to replicate.
3. Click Congure replication to open the Congure Replication Settings dialog box.
4. Select the replication partner for the volume collection and make sure each volume is congured to replicate to the selected
partner:
• Click the not replicated link if a volume is not congured for replication, and congure the volume.
• Click the partner name link if a volume is congured to replicate to a dierent partner. Modify the volume replication
conguration and change the partner.
5. Click OK.
Display Replication Activity and Replicas for a Volume Collection
To display replication activity and replicas for a volume collection:
1. Click Volumes.
2. Expand Volume Collections and then select the collection name.
3. Click the Replication tab.
The Replication Summary panel shows:
• Replication partner for the collection
• Replication schedules for the volume collection, including the next scheduled replication operation, if any
The Remote Replicas panel shows the replica collections for the volume collection. Expand a replica collection to see the individual
replicas and their status.
Modify Volume Collection Replication Conguration Settings
You can modify the replication conguration of a volume collection or of the volumes in the collection.
1. Click Volumes.
2. Expand Volume Collections and then select the collection that you want to modify.
3. Click Modify replication settings to open the Volume Collection – Modify Replication Settings dialog box.
4. To modify the settings, double-click the volume in the collection list to open up the replication settings for that volume. Make
adjustments for each volume as necessary.
5. Click OK to save your changes.
About Replicas
Similar to a snapshot, a replica represents the contents of a volume at the time the replica was created. Each replicated volume has a
replica set, which is the set of replicas created over time. You can create replicas of individual volumes or volume collections. You can
create replicas manually at any time, or you can set up a schedule.
Individual replicas are identied by the date and time that the replication operation started. The replica set name is based on the
volume name and includes a dot-number extension to ensure that all replica set names are unique, in case two dierent partners
replicate volumes with the same name to the same group. The number in the extension reects the order that each partner was
congured as a replication partner to the group. For example, all replica sets from the rst congured partner have a dot-1 extension
(such as dbase.1). Replica sets from the next congured partner have a dot-2 extension (such as dbase.2).
