• Replication operation status and replica status.
2. In the Remote Replicas panel, click
Replication History to show details about each replication operation:
• Time the operation started.
• Replication partner.
• Total replication time. The duration time includes the amount of t
ime during which replication was paused
or the network was down.
• Amount of data transferred.
• Data transfer speed.
• Status of the replication.
Replicating volume collections
Volume collections enable you to perform an operation on multiple volumes at the same time.
If you replicate a volume collection, the resulting set of replicas is calle
d a replica collection. When complete, a
replica collection contains one replica for each volume in the collection. A replica collection set is the set of all the
replica collections for a volume collection.
Requirement: Before
you can replicate a volume collection, the volumes in the collection and the volume
collection must be configured to replicate to the same partner. See Configuring a volume for
replication on
page 12-25 and Configuring a volume collection for replication on page 12-26.
1. Click
Volumes, then expand Volume Collections, then select the collection, and then click Create
replica now.
2. In the Create Replica Collection dialog box:
• If you want to perform the replication using manual t
ransfer replication, select Perform manual
replication
. See About manual transfer replication on page 12-3.
• Click
Yes to start the replication.
You should monitor replication to make sure replicas complete in
a timely manner. See Displaying replication
activity and replicas for a volume collection on page 1
2-29.
If replication operations are taking longer than expected, make sure you have adequate network bandwidth
between the groups, in addition
to full IP routing. A slow network link can cause long replication times.
Displaying replication activity and replicas for a volume collection
Click Volumes, then expand Volume Collections, then select the collection name, and then click the
Replicas tab.
In the Volume Collection Replicas wind
ow, the Replication Summary panel shows:
• Replication partner for the collection.
• Replication schedules for the volume collection, including the next
scheduled replication operation, if any.
