A.3 Considerations for installing a pair management server
(open system)
To ensure adequate performance when collecting information in an open system, we recommend that you use a
pair management server where the XP Replication Monitor agent is installed to manage the copy pairs to be
monitored.
When monitoring the copy pairs that are not managed on a pair management server where the XP Replication
Monitor agent is installed (such as copy pairs that are not defined in a Raid Manager XP configuration definition
file), XP Replication Monitor software collects information from all the storage subsystems, using the Device
Manager's refresh function. The refresh function updates the database maintained by Device Manager with the
volume information and configuration information recorded in the connected storage subsystems. This processing
may take from a few minutes to several tens of minutes for each storage subsystem.
