Glossary
access method An IBM-specific term for software that moves data between main storage and I/O devices to
create channel programs and manage system buffers.
AL Arbitrated loop.
allocation The ratio of allocated storage capacity versus total capacity as a percentage. Allocated storage
refers to those logical devices (LDEVs) that have paths assigned to them. Allocated storage capacity
is the sum of the storage of these LDEVs. Total capacity is the sum of the capacity of all LDEVs
on the disk array.
ambient
temperature
The air temperature in the area where a system is installed. Also called intake temperature or
room temperature.
array group A group of four or eight physical hard disk drives (HDDs) installed in a P9000 or XP disk array
and assigned a common RAID level. RAID1 array groups consist of four (2D+2D) or eight HDDs
(4D+4D). RAID5 array groups include a parity disk, but also consist of four (3D+1P) or eight
HDDs (7D+1P). All RAID6 array groups are made up of eight HDDs (6D+2P). This is also known
as a parity group or a RAID group.
BC P9000 or XP Business Copy. An HP application that provides volume-level, point-in-time copies
in the disk array.
BC Z The version of Business Copy that supports mainframe volumes.
CB Circuit Breaker.
CHA Channel adapter. A device that provides the interface between the array and the external host
system. Occasionally, this term is used synonymously with the term channel host interface processor
(CHIP).
CLI Command-line interface. An interface comprised of various commands which are used to control
operating system responses.
Cnt Ac-J P9000 or XP Continuous Access Journal software.
Cnt Ac-J Z The version of Continuous Access Journal that supports mainframe volumes.
Cnt Ac-S P9000 or XP Continuous Access Synchronous software.
Cnt Ac-S Z The version of Continuous Access Synchronous that supports mainframe volumes.
CU Control Unit. Used to organize the storage space attached to the disk controller (DKC). You can
group similarly configured logical devices (LDEVs) with unique control unit images (CUs). CUs
are numbered sequentially. The disk array supports a certain number of CUs, depending on the
disk array model. Each CU can manage multiple LDEVs; therefore, both the CU number and the
LDEV number are required to identify an LDEV.
CVS CVS devices (OPEN-x CVS or 3390-x CVS) are custom volumes configured using array
management software to be smaller or larger than normal fixed-size OPEN or mainframe system
volumes. Synonymous with volume size customization (VSC). OPEN-V is a CVS-based volume.
C-Track Continuous Track. An HP software program that detects internal hardware component problems
on an array and automatically reports them to HP Support Services.
DFSMS Data Facility Storage Management Subsystem.
DKA Disk adapter.
DKC Disk controller.
DKU Disk Unit.
emulation mode The LDEVs associated with each RAID group are assigned an emulation mode that makes them
operate like OPEN system disk drives. The emulation mode determines the size of an LDEV or
volume.
OPEN-V: User-defined custom size
3390-3/3R: 2.838 GB
3390-9: 8.514 GB
3390-L: 27.844 GB
