System requirements for managing copy pairs
In Device Manager , the following components can be used to manage copy pairs:
• GUI
By launching the Replication Manager GUI from the Device Manager GUI, you can define copy
pairs or change pair statuses. Even if the Replication Manager license is not registered, you can
use a part of the Replication Manager functionality by only using the Device Manager license.
• CLI
You can use the Device Manager CLI to define copy pairs or change pair statuses.
The following sections describe the system configurations and requirements to manage copy pairs by
using Device Manager.
System configuration for managing copy pairs
In Device Manager, the following configurations can be used to manage copy pairs:
• Local management method
In this configuration, copy pairs are managed for each host by connecting a command device to
each application server via Fibre Channel.
• Configuration that uses a pair management server (central management method)
In this configuration, copy pairs are centrally managed by connecting a command device to a
computer other than application servers (pair management server) via Fibre Channel.
• Configuration that uses a virtual command device server
In this configuration, a command device is connected to a computer (virtual command device
server) via Fibre Channel, and then copy pairs are managed by a computer on the LAN via the
virtual command device server.
• Configuration that uses SVP
In this configuration, copy pairs are directly managed by using an SVP as a virtual command
device instead of managed by using a storage system physical command device. You do not need
to prepare a command device for the storage system. This configuration is supported only when
both the P-VOL and S-VOL exist in P9500.
There are two types of configurations: configurations in which copy pairs are defined and managed
by using a configuration definition file, and configurations in which copy pairs are defined and
managed as a device group
