Web browser on a management client
The Web browser collects the host, storage subsystem, and copy pair information (#1) maintained in the
database from XP Replication Monitor server on the management server, and displays this information in a
window.
In response to a request from a user to update the copy pair configuration information (#2) or copy pair
status (#2), the web browser asks the management server to update the information in the XP Replication
Monitor server database. In response to a request from a user to change the copy pair status (#2), the web
browser asks the Device Manager server on the management server to implement the pair status change.

The XP Replication Monitor server collects the following information from the Device Manager server, and
from the XP Replication Monitor agent on the pair management servers, and updates this information in the
XP Replication Monitor server database:
• Configuration information on copy pairs managed by the pair management servers (#3)
• Information indicating the pair status of copy pairs managed by the pair management servers (#4)
