link
A connection between ports on Fibre Channel devices. The link is a full duplex
connection to a fabric or a simplex connection between loop devices.
logon
Also
called login, it is a procedure whereby a user or network connection is
identified as being an authorized network user or participant.
loop
See
arbitrated loop
.
loop ID
Seven-bit values numbered contiguous from 0 to 126 decimal that represent the
127 valid AL_PA values on a loop (not all 256 hexadecimal values are allowed
as AL_PA values per Fibre Channel).
loop pair
A Fibre Channel attachment between a controller and physical disk drives.
Physical disk drives connect to controllers through paired Fibre Channel arbitrated
loops. There are two loop pairs, designated loop pair 1 and loop pair 2. Each
loop pair consists of two loops (called loop A and loop B) that operate
independently during normal operation, but provide mutual backup in case one
loop fails.
LTEA
Last Termination Event Array. A two-digit HSV Controller number that identifies
a specific event that terminated an operation. Valid numbers range from 00 to
31.
LUN
Logical Unit Number. A SCSI convention used to identify elements. The host sees
a virtual disk as a LUN. The LUN address a user assigns to a virtual disk for a
particular host will be the LUN at which that host will see the virtual disk.
management
agent
The HP Command View EVA software that controls and monitors the Enterprise
storage system. The software can exist on more than one management server in
a fabric. Each installation is a management agent.
management
agent event
Significant occurrence to or within the management agent software, or an
initialized storage cell controlled or monitored by the management agent.
