Node name See WorldWide Name (WWN).
NVRAM NVRAM stands for NonVolatile Random Access Memory.
Small amounts of NVRAM save configuration parameters.
Values are changed with a configuration utility and are
retained when power is removed.
ONC ONC stands for Open Network Computing, a remote
procedure call developed by Sun Microsystems.
Path A path to a device is a combination of a QLA2xxx adapter
and a target port. Note that this is distinct from any internal
paths within the fabric network. A fabric network appears
to the operating system as an opaque network between the
host bus adapter (initiator) and the target port.
Since a path is a combination of a host bus adapter and a
target port, a path is distinct from another path if it accessed
through a different host bus adapter, and/or it is accessing a
different target port. Consequently, when switching from
one path to another, the driver might be selecting a different
QLA2xxx adapter (initiator), a different target port, or both.
This will make a difference to the driver when selecting the
proper method of failover notification. It can make a
difference to the target device, which might have to take
different actions when receiving retries of the request from
another initiator or on a different port.
Point to point Two Fibre Channel nodes directly connected (non-loop).
Port Ports are access points in a device where a link attaches.
There are four types of ports, as follows:
❑ N_Port is a Fibre Channel device port that supports
point-to-point topology.
❑ NL_Port is a Fibre Channel device port that supports
loop topology.
❑ F_Port is a port in a fabric where an N_Port may attach.
❑ FL_Port is a port in a fabric where an NL_Port may
attach.
Port name A port name is the unique name of a port on a Fibre Channel
device. A WorldWide Name (WWN) may have several port
names associated with it (one port name for each port).
Protocol A protocol is a convention for data transmission that defines
timing, control, format, and data representation. SCSI, IP,
and VI are protocols.
QMS QMS stands for QLogic Management Suite.
