In-process replication activity between groups
Amount of free delegated space
If free delegated space is low and the replica volume reserve for each replicated volume has not reached its maximum (and,
therefore, can increase), consider increasing the delegated space.
About Monitoring Replication Operations
If you are replicating volume data, you should monitor replication operations to make sure that each operation completes.
From the Monitoring tab in the navigation panel, you can see information about:
Outbound replication (all volumes on the group congured for replication)
Inbound replication (all replica sets stored in the group from all partners replicating to this group)
Replication history (history of all outbound replications)
Replication schedules
In addition, you should monitor the usage of delegated space. If free delegated space is not available, replica reserve cannot increase
automatically. You can also monitor replica reserve for a volume. Insucient replica reserve limits the number of replicas.
Best Practices for Replication Monitoring
Table 63. Replication Monitoring Best Practices identies some best practices for monitoring replication between groups.
Table 63. Replication Monitoring Best Practices
Monitor Description
Incomplete replication operations If a replication operation fails to complete, you might need to increase replication space.
Incomplete manual transfer
operations or failback operations
Some operations require multiple tasks that administrators must complete. Make sure you
complete all multitask operations.
Low free delegated space If delegated space is low, replica reserve space might not be able to increase automatically
to store new replicas.
Number of replicas If too many replicas exist, consider decreasing the replica reserve percentage. If too few
replicas exist, consider increasing the replica reserve percentage.
A low free replica reserve can indicate optimal use of replica reserve space, if the desired
number of replicas exist.
Monitor Inbound Replication
Inbound replication transfers volume data from a replication partner to the current group.
To monitor inbound replication:
1. Click Monitoring.
2. Select Inbound Replication.
The Inbound Volume Replication panel displays a list of volumes. Select a volume name to display statistics about that volume.
Monitor Outbound Replication
Outbound replication transfers volume data from the current group to a replication partner.
To monitor outbound replication:
1. Click Monitoring.
2. Select Outbound Replication.
