HP StorageWorks XP Replication Monitor software installation and configuration guide (T1784-96008, November 2006)

Appendix B Glossary 117
Appendix B Glossary
application server The machine on which application programs are installed. Also called the host. The host uses
the storage subsystem as an external storage device.
In an open system, information about the host can be acquired if a Device Manager agent is
installed on the host.
In a mainframe system, the host on which Business Continuity Manager is installed is also
called the pair management server. The pair management server can acquire copy pair
configuration and status information about the copy pairs it manages.
batch collection
command for
maintenance
information
Software that collects necessary information, such as log files and property files, related to a
problem that cannot be resolved at the user level for forwarding on to customer support.
Business Continuity
Manager
Software used to control the storage subsystem from the host in a mainframe system. Using
Business Continuity Manager to issue commands from the host to the storage subsystem, you
can acquire copy pair configuration and status information. A XP Replication Monitor server
acquires information about copy pair configuration and status in conjunction with Business
Continuity Manager.
Business Copy XP Software provided by the storage subsystem, used to duplicate volumes within a storage
subsystem. For more information, see the Business Copy XP manual.
cascade structure A structure of consecutive copy pairs. In a cascade structure, the secondary volume of a given
copy pair coincides with the primary volume of another copy pair. This volume is called the
secondary/primary volume (SP-VOL).
cluster configuration In the XP Replication Monitor operating environment, the term cluster configuration refers to the
configuration of duplicated management servers consisting of an executing node and a
standby node.
cluster software Software required to be installed on management server nodes to boost overall availability by
duplicating management servers as a cluster system. Available software depends on the OS
that runs on the management server.
Command View XP
AE Suite Common
Component
A component that provides functionality common to all Command View XP AE Suite products,
including login, output log, and web services. Installed as part of a XP Replication Monitor
server.
Command View XP
AE Suite common
log file
A log file for detailed information on events such as server startup. Used to check errors that
occur during XP Replication Monitor operation.
Continuous Access
XP Journal
Software provided by the storage subsystem and used to asynchronously duplicate volumes
between storage subsystems. For more information, see the Continuous Access XP Journal
manual.
Continuous Access
XP Synchronous
Software provided by the storage subsystem, used to duplicate volumes between storage
subsystems. For more information, see the Continuous Access XP Synchronous manual.
copy group A group of multiple copy pairs. Operations such as pair status modification apply to all copy
pairs in the group.
copy pair Denotes a primary and secondary volume pair linked by the volume replication function of the
storage subsystem. Also called a pair volume. In this manual, copy pair is sometimes written
simply as
pair.
copy pair state Indicates in detail the current state of a copy pair status. Each copy pair state value is
categorized into one of the six copy pair status values used in XP Replication Monitor software
(error, suspend, copying, sync, simplex, and unknown).
copy pair status Indicates the current status of the copy pair. XP Replication Monitor software uses six status
values: error, suspend, copying, sync, simplex, and unknown. Also called pair status.
copy progress Progress status of the volume replication function performed by the storage subsystem. XP
Replication Monitor software displays the copy progress, according to the copy pair status, for
items that are Active or Inactive. For Active items, the copy progress is displayed when the
copy pair status is copying or sync. For Inactive items, the copy progress is displayed when the
