management server.
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. Pair status is also
called copy pair status.
paired volume Denotes a primary and secondary volume pair linked by the volume replication function of the
storage subsystem. Also called a copy pair. In this manual, copy pair is sometimes written
simply as pair.
prefix The name of the prefix portion of the copy group definition file (prefix.GRP.copy-group-id)
created by Business Continuity Manager. XP Replication Monitor software uses the prefix as a
unique name to identify copy group definition files created by Business Continuity Manager.
primary volume (P-
VOL)
The source volume that is copied to another volume using the volume replication function of the
storage subsystem.
property files Generic term for the files that define the XP Replication Monitor operating environment. The XP
Replication Monitor operating environment can be modified by changing the appropriate
property files.
RAID Manager XP Software used to control the storage subsystem from the host in an open system, which is used
to control storage subsystem volume duplication features (such as Continuous Access XP
Synchronous and Business Copy XP) by issuing commands from the host to the storage
subsystem, and also is used for gathering information about pair configuration in the storage
subsystem. XP Replication Monitor software acquires information about copy pair configuration
and status in conjunction with a Device Manager server, a Device Manager agent, and RAID
Manager XP.
refresh The term refresh refers to updating the database that is maintained by the XP Replication
Monitor server, by using the most recent information. This database stores copy pair
configuration information and copy pair status information obtained from the Device Manager
server, the XP Replication Monitor agent, and Business Continuity Manager.
secondary volume
(S-VOL)
The destination volume to which the primary volume is copied using the volume replication
function of the storage subsystem.
secondary-primary
volume (SP-VOL)
The volume located in the middle of the cascade structure, when a cascade structure is used by
the volume replication function of the storage subsystem. Indicates the secondary volume in an
upper level copy pair and the primary volume in a lower level copy pair.
Snapshot XP Software provided by the storage subsystem, used to duplicate volumes within a storage
subsystem. For more information, see the Snapshot XP manual.
subsystem An external storage device (storage subsystem) connected to the host. In this manual,
subsystem means storage subsystem.
trace log file A log file containing detailed program processing information, used to analyze program
processing in the event of an error during XP Replication Monitor software operation.
volume A collective name for the logical devices (LDEVs) and logical units (LUs) that are created in the
storage subsystem.
volume replication
functions
Generic term used in this manual to refer to high-speed volume replication functions in the
storage subsystem (such as Business Copy XP and Continuous Access XP Synchronous). The
mirror control function provided by the storage subsystem can be used to quickly create a
replica of the volume without passing through the LAN.
