Fibre Channel Protocol.
Host bus adapter.
Hewlett-Packard Company.
Logical device. An LDEV is created when a RAID group is divided into
sections using a selected host emulation mode (for example, OPEN-9 or
OPEN-M). The number of resulting LDEVs depends on the emulation mode.
"LDEV" and "volume" are synonyms.
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.
Logical Unit Size Expansion, a feature which logically combines LDEVs
so they appear as a larger LDEV. This allows a LUN to be associated with 2
to 36 LDEVs. LUSE allows applications to access data requiring large
amounts of disk space.
Open Fibre Control.
A general term describing any one of the supported OPEN emulation
modes (for example, OPEN-L).
Operating system.
Physical address.
"Path" and "LUN" are synonymous. Paths are created by associating a port,
a target, and a LUN ID with one or more LDEVs.
A connector on a channel adapter card in the disk array. A port passes data
between the disk array and external devices, such as a host server. Ports are
named using a port group and port letter, for example, CL1-A.
Redundant array of independent disks.
