HP Storage Essential
HP Storage Essential acts as the main console for heterogeneous storage infrastructure management
software, providing SAN visualization and reporting, asset management, performance and capacity
monitoring and planning, and policy-driven event management.
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 configurations 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 the management server by using SVP
as a virtual command device instead of a storage system 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.
NOTE:
• If copy pairs are managed in a configuration that uses an SVP (the out-of-band method), the
processing time of Replication Manager might increase because the command response time of
RAID Manager tends to increase, compared to when copy pairs are managed in a configuration
that uses a physical command device (the in-band method).
• In SVP configurations, you can use the GUI to check the configuration of and change the pair
status of copy pairs defined as device groups.
