HP XP RAID Manager Software - Manual (Page 178)

FICON Fibre connectivity. An FC layer 4 protocol used to map mainframe channel command and data
I/O operations onto standard FC infrastructure, protocol, and FC services.
HBA Host bus adapter.
HDD Hard disk drive.
IMPL Initial microprogram load.
LCP Local control port.
LDKC Logical disk controller.
local disk A disk in the local array. Sometimes refers to a disk in a local host.
LUN Logical unit number. A LUN results from mapping a logical unit number, port ID, and LDEV ID to
a RAID group. The size of the LUN is determined by the emulation mode of the LDEV and the
number of LDEVs associated with the LUN.
LUSE Logical Unit Size Expansion. The LUSE feature is available when the HP StorageWorks LUN
Manager product is installed, and allows a LUN, normally associated with only a single LDEV,
to be associated with 1 to 36 LDEVs. Essentially, LUSE makes it possible for applications to access
a single large pool of storage.
MPB MSL to MicroProcessor Blade
MSCS Microsoft Cluster Service.
OPEN- x A general term describing any of the supported OPEN emulation modes (for example, OPEN-E).
There are two types of OPEN-x devices: legacy OPEN-x devices with a fixed size (such as OPEN-3,
OPEN-8, OPEN-9, and OPEN-E), and OPEN-V, which has a variable size and is a CVS-based
volume.
ORM Online Read Margin
P-VOL Primary volume.
path A path is created by associating a port, a target, and a LUN ID with one or more LDEVs. Also
known as a LUN.
PCB Printed circuit board.
PDEV Physical device.
port A physical connection that allows data to pass between a host and the disk array. The number
of ports on a disk array depends on the number of supported I/O slots and the number of ports
available per I/O adapter. The P9000 and XP family of disk arrays supports Fibre Channel (FC)
ports and other port types. Ports are named by port group and port letter, such as CL1-A. CL1 is
the group; A is the port letter.
RAID level A configuration of disk drives that uses striping, mirroring, and parity to improve performance
and data availability and reliability.
RAID Manager The CLI configuration and replication tool for the P9000 or XP disk array that system administrators
can use to enter RAID Manager commands from open-system hosts to perform Continuous Access,
Business Copy, Database Validator, and Data Retention operations, as well as provisioning
commands on logical devices.
RAID1/5 Specific RAID architectures.
RCU Remote control unit.
Remote Web
Console A browser-based program installed on the SVP that allows you to configure and manage the disk
array.
RIO Remote I/O.
S-VOL Secondary or remote volume. The copy volume that receives the data from the primary volume.
SAS Serial Attached SCSI.
SATA Serial Advanced Technology Attachment.
SIM Service information message.
SVP Service processor. A computer built into a disk array. The SVP, used only by an HP service
representative, provides a direct interface to the disk array.
