Figure 9 Data collection (open systems)
Acquiring configuration and license information
Replication Manager acquires the following information via Device Manager server:
• Copy pair configuration information
• Volume configuration information (including the command device, pool volumes, and journal
volumes)
• License information for the volume replication functionality
Device Manager server stores information acquired from storage systems, while Replication
Manager stores information acquired from Device Manager server.
Information for performing remote copy between multiple sites (in which a copy pair is defined
between multiple Device Manager servers) is acquired via Device Manager Agent because
this information cannot be retained by Device Manager server.
Acquiring copy pair statuses
Replication Manager sends a request to Device Manager Agent, which in turn uses RAID Manager
to collect the status of copy pairs from the storage system.
For a copy pair defined by the storage system (such as Remote Web Console ), the status is ac-
quired from Device Manager server because the RAID Manager configuration definition file is
not available.
