host mode

Each port can be configured for a particular host type. These modes are

represented as two-digit hexadecimal numbers. For example, host mode 08

represents an HP-UX host.

LD, 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-9). The number of resulting LDEVs depends on the selected emulation

mode. The term LDEV is also known as 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

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.

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.

Physical address.

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.

port

A physical connection that allows data to pass between a host and a disk array.

RAID

Redundant array of independent disks.

R-SIM

Remote service information message.

SCSI

Small Computer Systems Interface. A standard, intelligent parallel interface for

attaching peripheral devices to computers, based on a device-independent

protocol.

SIM

Service information message.

SNMP

Simple Network Management Protocol. A widely used network monitoring and

control protocol. Data is passed from SNMP agents, which are hardware and/or

software processes reporting activity in each network device (hub, router, bridge,

and so on) to the workstation console used to oversee the network. The agents

return information contained in a MIB (Management Information Base), which

is a data structure that defines what is obtainable from the device and what can

be controlled (turned off, on, and so on).

STMS

Sun StorEdge Traffic Manager.

SVP

Service processor. A notebook computer built into the disk array. The SVP

provides a direct interface to the disk array and used only by the HP service

representative.
