R_CTL
Route control. The first eight bits of the header, which defines the type of frame and its contents.
R_RDY
Receiver ready. A primitive signal indicating that the port is ready to receive a frame.
R_T_TOV
Receiver transmitter timeout value, used by receiver logic to detect loss of synchronization between transmitters and
receivers.
RAID
Redundant array of independent disks. A collection of disk drives that appear as a single volume to the server and
are fault tolerant through mirroring or parity checking. See also
RCS
Reliable Commit Service.
remote switch
An optional product for long-distance fabrics, requiring a Fibre Channel-to-ATM or SONET gateway.
responder
The N_Port with which an exchange originator wishes to communicate.
RLS
Read Link Status.
route
As applied to a fabric, the communication path between two switches. May also apply to the specific path taken by

.
RSCN
Registered state change notification. A switch function that allows notification of fabric changes to be sent from the
switch to specified nodes. The fabric controller issues RSCN requests to N_Ports and NL_Ports, but only if they have
registered to be notified of state changes in other N_Ports and NL_Ports. This registration is performed via the State
Change Registration (SCR) Extended Link Service. An N_Port or NL_Port can issue an RSCN to the fabric controller
without having completed SCR with the fabric controller.
RTWR
Reliable transport with response. May appear as a task in
portlogdump
command output.
running disparity
A binary parameter that indicates the cumulative disparity (positive or negative) of all previously issued transmission
characters.
