LDEV

Logical device. An LDEV is created when a RAID group is carved into pieces

 

according to the selected host emulation mode (that is, OPEN-3, OPEN-8,

 

OPEN-L). 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 LUN Configuration 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-L).

OS

Operating system.

PA

Physical address.

path

“Path” and “LUN” are synonymous. Paths are created by associating a port,

 

a target, and a LUN ID with one or more LDEVs.

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.

remote console PC

The PC running HP StorageWorks Remote Control XP.
