Copy pair status
An alert is sent when a copy pair or copy group achieves a specified status. For example, you can
specify a condition for a copy group so that an alert is sent when an error status is detected. In this
case, an alert is sent indicating the copy pairs of the group that are in error status. When all the
constituent pairs attain Completed status, the copy group is given the Completed status.
CAUTION:
Even if the status of constituent pairs in the copy group changes again, the copy group remains in
the Completed status.
Performance threshold
An alert is sent when a performance metric exceeds the preset threshold. You can specify the thresholds
for the following performance metrics:
• Write delay time (C/T delta) in seconds on a copy group basis
• Pool volume usage on a pool basis (open systems)
• Sidefile usage on a copy group basis
In open systems, you can specify the thresholds for the sidefiles on the primary and secondary
volumes. In mainframe systems, you can only specify the threshold for the primary volume.
• Journal volume usage on a copy group basis
In open systems, you can specify the journal volume usage thresholds for the primary and secondary
volumes. In mainframe systems, you can also specify the thresholds for metadata.
Copy license usage threshold
An alert is sent when the copy license usage exceeds a preset threshold. Replication processes are
disabled immediately once this threshold is exceeded. It is therefore necessary to set a license usage
threshold value that provides enough time to add additional license capacity.
NOTE:
You can specify the copy license usage threshold if the version of the Device Manager server (acting
as the information source) is 6.1 or later.
Alert completion
Alerts are automatically marked as Completed according to the criteria in the following table.
Table 7 Alert completion conditions
Completion criteria Monitored condition
When current usage is less than or equal to the usage
(%) specified for the alert.
• Pool usage for each pool
• Journal usage for each journal group
• License usage
• Sidefile and journal volume usage
