configuration
definition file

The text file which defines connected hosts and the volumes and groups known
to the P9000 RAID Manager instance. Physical volumes (special files) used
independently by the hosts are combined when paired logical volume names
and group names are given to them. The configuration definition file establishes
the correspondence between the physical volumes used by the hosts, the paired
logical volumes and the names of the remote hosts connected to the volumes.
Also referred to as a P9000 RAID Manager configuration definition file or
HORCM configuration definition file.

consistency group

A group used as a unit in Continuous Access, or Continuous Access Journal that
maintains integrity of the update order for volumes.

copy group

A group of copy pairs. You can perform operations, such as modifying pair
statuses, on all the copy pairs in the group.

copy group
configuration
definition

A list of copy pairs. In a mainframe environment, it refers to a file containing a
list of copy pairs managed by HP StorageWorks P9000 for Business Continuity
Manager Software. The data in the file is created or added to when a copy pair
is defined. The file name matches the copy group. In an open system environment,
it is also referred to as copy pair configuration definition.

copy group
container
(container)

A collection of copy groups (consistency groups) available only in a mainframe
environment.

copy group list

A list of copy group configuration definitions.

copy pair

Denotes a primary and secondary volume pair linked by the volume replication
functionality of a storage system. Also called

paired volumes

. In this manual,

copy pair

is sometimes referred to simply as a

pair

.

copy pair state

A value that represents the status of both a primary volume and a secondary
volume. The copy pair state displayed in Replication Manager corresponds to
the copy pair status displayed in prerequisite products (such as Device Manager,
P9000 RAID Manager, and HP StorageWorks P9000 for Business Continuity
Manager Software) and in storage system operation management software (such
as Remote Web Console).

copy pair status

A value that represents the status of a copy pair. Six status values are defined
in Replication Manager:

error

,

suspend

,

copying

,

sync

,

simplex

, and

unknown

. Each status is indicated by an icon. The copy pair status is determined

by the combination of the copy pair states of the primary and secondary volumes.
Also called

pair status

.

copy progress

Progress status of the volume replication functionality executed by the storage
system. Replication Manager displays the copy progress, which depends on 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 copy pair status is

error

or

suspend

.

Comma Separated Value

CU (Control Unit)

A virtual control unit created in a storage system. Also called a CU image. The
LDEVs created in a storage system are connected to a single CU, and a number
is assigned to each CU for identifying its LDEVs. Therefore, volumes (LDEVs) in
a storage system are specified by the CU number (CU#) and LDEV number.
