HP XP7 Replication Manager Configuration Guide (TK981-96012, May 2014)

NOTE:
Replication Manager acquires configuration information from the Device
Manager server at the following times:
• For a local Device Manager:
The configuration management information displayed in each window is
acquired from Device Manager when each source management window of
Replication Manager is displayed. You need not manually refresh the system
configuration information before using Replication Manager to set up a
storage system or define copy pair configurations.
• For a remote Device Manager, all configuration information is acquired
when a configuration refresh is performed.
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 XP7 Remote Web Console), the status is
acquired from Device Manager server because the RAID Manager configuration definition file is
not available.
Acquiring performance information
Replication Manager issues a request to Device Manager Agent to acquire performance inform-
ation (such as the sidefile usage rate, pool volume usage rate, and write delay time (C/T delta)).
In turn, Device Manager Agent uses RAID Manager to obtain the data from the storage system.
Creating and deleting copy pairs and changing copy pair statuses
Replication Manager issues a request to Device Manager Agent to create and delete copy pairs
or to change the status of copy pairs. The Device Manager Agent uses RAID Manager to perform
the operations on the storage system.
Data collection in mainframe systems
This section describes the data collection and flow of processing between programs in mainframe
systems.
