Table 15-3 describes some best practices for monitoring replication between groups. The first column lists the
monitoring condition, the second column describes it,
and the third column provides a reference for more
information about addressing the issue.
Table 15-3: Replication Monitoring Best Practices
Monitor Description Reference
Incomplete replication
operations
If a repl
ication operation fails to complete, you might need to
increase replication space.
See Monitoring replication on
page 15-5
Incomplete manual
transfer operation
s or
failback operations
Some operations require multiple tasks that administrators must
co
mplete. Make sure you complete all multi-task operations.
See Monitoring replication on
page 15-5
Low free delegated
space
If delegated space is low, replica reserve space might not be able to
increase automatically to s
tore new replicas.
See Monitoring a specific
partner on page 15-10 and

on page 15-8
Number of replicas If too many replicas exist, consider decreasing the replica res
erve
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.

Monitoring outbound replication
Outbound replication transfers volume data from the current group to a replication partner.
To monitor outbound replication, click
Monitoring and then Outbound Replication. The Outbound
Replication panel provides the following information:
• Volume and partner name
• Transfer status, start time, and amount of data transferred
See the online help for information about the data fields and options.
To see more detail about a volume in the list, move
the pointer over t
he volume name. A pop-up window appears,
listing the following:
• Volume name
• Storage pool
• Thin provisioning status (enabled or disabled)
• Reported size, volume reserve, and snapshot reserve
• Current and requested status (online or offline)
• Access type (read-write permission and whether shared for cluster access)
• Replication partner
• Description, if any
