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
Manager Software. Depending on the type of volume scan, volumes are assigned
the local DAD, Non Gen'ed DAD, or remote DAD attribute.
DAD ID A name that identifies a DAD.
dataset Defines the location for storing a file (a volume area accessible by applications)
on the mainframe host and defines the attribute values of that file. Creation of a
file on the mainframe host requires that a dataset be assigned in advance.
delta resync A status in which synchronization processing is performed by copying differential
data to an Continuous Access Journal copy pair in which part of the copy pair
exists on the local site and part exists on a remote site in a 3DC Multi-Target
configuration.
device group An LDEV grouping function supported by HP P9500 storage systems. (Also known
as a copy group defined within a storage system.)
Device Manager Software that enables integrated management of disk resources and the hardware
configuration of storage systems. Device Manager can be used to operate and
manage a system consisting of multiple HP StorageWorks XP disk array .
DEVN (Device
Number) A device number that is assigned to identify an LDEV when it is being used by
a mainframe system. A DEVN is expressed as a 4-digit hexadecimal number.
disk configuration
definition file A file containing a list of volumes managed by HP StorageWorks P9000 for
Business Continuity Manager Software. The data in the file is created or added
to when volume discovery is performed. The file name matches the DADID.
disk list A list of disk configuration definition files.
DKC Disk Controller
Dummy DEVN A dummy DEVN is assigned by the user during a Non Gen'ed scan or remote
scan. This information allows HP StorageWorks P9000 for Business Continuity
Manager Software to manage volumes to which no DEVNs have been assigned
by the mainframe host.
Extended
Consistency Group
(EXCTG) An attribute for maintaining data integrity between the copy pairs contained in
consistency groups. In principle, each copy group container is assigned this
attribute. This attribute ensures data integrity between P-VOLs and S-VOLs across
multiple storage systems. This attribute is available only in a mainframe
environment.
FC Fibre Channel
Gen’ed Volume A volume recognized by a mainframe host.

HORCM HP StorageWorks Continuous Access Synchronous
HORCM Instance The basic unit of P9000 RAID Manager software structure. Each copy of a P9000
RAID Manager on a server is a P9000 RAID Manager instance. Each instance
uses a defined configuration file to manage volume relationships while
maintaining awareness of the other P9000 RAID Manager instances. Each P9000
