• Maximum reserve, snapshot reserve, and free space
• How the latest replication occurred (ove
r the network or through Manual Transfer Replication)
• Whether a failback snapshot is enabled
• Current and operational status (online or offline)
• Number of replicas in the replica set
• Description, if any
Click a replica set name or double-click a ro
w to navig
ate to the Inbound Replicas window for that partner, with the
replica set selected and its detail shown.
Monitoring outbound replication history
To see replication history, click Monitoring and then Replication History. The Outbound Replication
History panel provides the following information:
• Volume and partner name
• Replication start time, duration, and status
• Amount of data transferred and the transfer speed
See the online help for information about the data fields and options.
Table 15-6 describes replica status and descriptions.
Table 15-6: Replica Status
Status Description
complete Replication operation is complete, and all the data is on the secondary group.
incomplete or
in progress Rep
lication operation is not complete.
A replication operation cannot start i
f another operation replication for the same
volume is in progress.
Periodically examine the replication duration information. If you see long replication times, make sure the network
connection between the partners is sufficient. A slow network link between the partners can cause long replication
times. If a replication operation makes no progress, the group generates a warning event. Make sure you have
adequate network bandwidth between the groups, in addition to full IP routing. If necessary, increase the network
bandwidth.
In the Transferred column, check how much
data yo
u are replicating. You might want to use manual transfer
replication if you are transferring a large amount of data.
Monitoring replication partners
You can display information about all the configured replication partners for a group. This information includes
both outbound details (volumes on this group replicating to others) and inbound (replication from other groups to
this group).
