OPEN-E). The number of resulting LDEVs depends on the selected emulation
mode. The term LDEV is often used synonymously with the term volume.
LUN
Logical unit number. A LUN results from mapping a SCSI 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.
For example, a LUN associated with two OPEN-3 LDEVs has a size of 4,693
MB.
LUSE
A LUN is normally associated with only a single LDEV. The LUSE feature allows
a LUN to be associated with 1 to 36 LDEVs. Essentially, LUSE makes it possible
for applications to access a single large pool of storage. The LUSE feature is
available when the HP StorageWorks XP Array Manager product is installed.
OFC
Open Fibre Control.
OPEN- x
A general term describing any one 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, OPEN-E), and
OPEN-V, which has a variable size and is a CVS-based volume.
PA
Physical address.
path
"Path" and "LUN" are synonymous. Paths are created by associating a port and
a LUN ID with an LDEV.
port
A physical connection that allows data to pass between a host and the disk
array. The number of ports on an XP disk array depends on the number of
supported I/O slots and the number of ports available per I/O adapter. The XP
family of disk arrays supports Fibre Channel (FC) ports as well as other port
types. Ports are named by port group and port letter, such as CL1-A. CL1 is the
group, and A is the port letter.
RAID
Redundant array of independent disks.
R-SIM
Remote service information message.
SCSI
Small computer system interface.
SIM
Service information message.
SNMP
Simple Network Management Protocol.
SVP
Service processor, which is the PC built into the disk array. The SVP provides a
direct interface into the disk array. SVP use is reserved for HP support
representatives only.
SVS
Storage Virtualization System, an appliance that manages multiple disk array
storage systems.
TID
Target ID.
Volume
On the XP array, a volume is a uniquely identified virtual storage device
composed of a control unit (CU) component and a logical device (LDEV)
component separated by a colon. For example 00:00 and 01:00 are two
uniquely identified volumes; one is identified as CU = 00 and LDEV = 00, and
the other as CU = 01 and LDEV = 00; they are two unique separate virtual
storage devices within the XP array.
