Glossary
AL Arbitrated loop.
AL-PA Arbitrated loop physical address.
array group A group of 4 or 8 physical hard disk drives (HDDs) installed in an XP disk array
and assigned a common RAID level. RAID1 array groups consist of 4 (2D+2D)
or 8 HDDs (4D+4D). RAID5 array groups include a parity disk but also consist
of 4 (3D+1P) or 8 HDDs (7D+1P). All RAID6 array groups are made up of 8
HDDs (6D+2P).
Command View
XP Advanced
Edition Software
HP StorageWorks Command View XP Advanced Edition Software, installs on
the user-provided Device Manager server and provides a browser-based platform
from which you can manage the SVS200 and the XP family of disk arrays—even
globally distributed arrays.
command device A volume on the disk array that accepts XP Continuous Access Software or XP
Business Copy Software control operations which are then executed by the disk
array.
CU Control Unit. Contains LDEVs and is approximately equivalent to SCSI Target ID.
CVS Custom volume size. CVS devices (OPEN-x CVS) are custom volumes configured
using array management software to be smaller than normal fixed-size OPEN
system volumes. Synonymous with volume size customization (VSC).
emulation modes The logical devices (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:
OPEN-3: 2.46 GB
OPEN-8: 7.38 GB
OPEN-9: 7.42 GB
OPEN-E: 13.56 GB
OPEN-L: 36 GB
OPEN-V: User-defined custom size
failover Disconnecting a failed unit or path and replacing it with an alternative unit or
path in order to continue functioning.
FC Fibre Channel.
FC-AL Fibre Channel arbitrated loop.
FCP Fibre Channel Protocol.
HBA Host bus adapter.
