HBA Host bus adapter.
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.
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 dep ends on the selected emulation
mode. The term LDEV i s often used synonymously with the term volume.
LUN Logical unit number. A LUN results from mapping a SCSI logical unit number ,
port ID, and LD EV I D to a RAI D g roup. 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 L D EVs has a size of 4,693 MB.
LUSE A LUN is normally associated with only a single L DEV. 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 and Security Manager
product is installed.
OFC Open Fi bre 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 m ore 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 p orts available per I/O adapter. The
XP family of disk arrays suppor ts 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.

Remote Web C on-
sole (RWC)

on the SVP that allows you to con figure a nd manage the disk array.
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 controller. The SVP
provides a direct interface into the disk array. SVP use is reserved for HP
support representatives only.
