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 .
CSV 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.
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.
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
