Modification of replication structures
Replication Manager provides capabilities to configure additional copy pairs as business operations
expand and improve performance by expanding buffer capacity for copying volumes. You can also
change pair states manually after error recovery. Using the wizards provided in the GUI, you can set
up pairs while visually keeping track of complex replication structures.

Architecture and components
Replication Manager works in conjunction with programs such as Device Manager, HP StorageWorks
P9000 for Business Continuity Manager Software and P9000 mainframe agent. Replication Manager
can be deployed using different system configurations depending on the type of hosts (open system
or mainframe system). Replication Manager can also be used in mixed environments that include both
types of hosts.
To view examples of system configurations (where Replication Manager of each management server
is in a cluster configuration between sites), see “
System configurations ” on page 24.
For specific system configurations and the system requirements, see the HP P9000 Replication Manager
Software Configuration Guide.
A typical system configuration comprises the following components:
• Management client: The machine on which the GUI for Replication Manager runs. Because the
GUI accesses the instance of Replication Manager on the management server through a Web
browser, no programs need to be installed on the management client.
• Management server: The management server at the local site is a machine running Replication
Manager and its prerequisite program, the Device Manager server. The management server
provides management information about Replication Manager in response to requests from man-
agement clients.
In an open system, the management server at the remote site is a machine running the Device
Manager server, which manages information about the hosts and pair management server at the
remote site. You can have Replication Manager manage the Device Manager server of the remote
site by registering the Device Manager server as an information source. (The Device Manager
server at the local site is automatically registered as an information source when you install Rep-
lication Manager.)
In a mainframe system, when the Device Manager server is installed on the management server
at the remote site and is managing the mainframe host, you can acquire detailed information
about the managed storage systems in Replication Manager by registering this Device Manager
server as an information source.
• Pair management server: A server used for collecting management information, such as copy pair
statuses and remote copying performance information. In an open system, P9000 RAID Manager
and a Device Manager agent need to be installed on this server. The pair management server
can also serve as a host. In a mainframe system, the host plays the same role as the pair manage-
ment server in an open system. For this reason, the mainframe host is sometimes called a pair
management server.
• Host (application server): A machine on which application programs are installed and uses a
storage system as an external storage device.
By installing a Device Manager agent on each host in an open system, you can use Replication
Manager to view information such as each host's IP address, mount point, and linked copy groups.
In a mainframe system, HP StorageWorks P9000 for Business Continuity Manager Software or
P9000 mainframe agent needs to be installed on the hosts. You can have Replication Manager
