HP StorageWorks P9000 Replication Manager Software 7.1.1 Configuration Guide (TB584-96029, September 2011)

cluster software Software 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.
consistency group A group used as a unit in Continuous Access or Continuous Access Journal that
maintains integrity of the update order for volumes.
Continuous Access Software that duplicates volumes between storage systems. Continuous Access
duplicates all data on the volumes. Two types of Continuous Access are provided:
Continuous Access Synchronous and Continuous Access Asynchronous. For more
information, see the Continuous Access manuals.
Continuous Access
Journal
Software that asynchronously duplicates multiple volumes between storage
systems. Continuous Access Journal temporarily stores differential data on a
journal volume and then duplicates the data. Continuous Access Journal can
duplicate data on remote sites; it can also be used to create 3DC multi-target
and cascade configurations among multiple sites. For more information, see the
Continuous Access Journal manuals.
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 pair Denotes a primary and secondary volume pair linked by the volume replication
functionality of a storage system. Also called a pair volume. In this manual,
copy pair is sometimes referred to simply as 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,
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.
CU (Control Unit) A virtual control unit created in an storage system. (Also known as 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.
DAD (Device
Address Domain)
A DAD is a group of volumes that is managed by HP StorageWorks P9000 for
Business Continuity Manager Software. Volumes are registered in a DAD during
a volume scan (discovery) by HP StorageWorks P9000 for Business Continuity
