Glossary channel-attached (1) Pertaining to direct attachment of devices by data I/O channels to a computer. (2) Pertaining to devices attached to a control unit by cables, not telecommunication lines (D). Synonymous with local. channel path CHP. A single interface between a central processor and one or more control units, along which signals and data are sent to perform I/O requests (D). channel path identifier CHPID. In a channel subsystem, a value assigned to each channel path of the system that uniquely identifies the path (D). See also channel-to-channel (channel-to-channel) (input/output configuration program). channel subsystem CSS. A collection of subchannels that direct the flow of information between I/O devices and main storage, relieve the processor of communication tasks, and perform path management functions (D). channel-to-channel CTC. A channel attached to another channel (channel-to-channel) and specifies the I/O mode of operation for the channel path under the I/O configuration program (IOCP) channel path identifier (CHPID) statement 'Type' parameter (D). See also channel path identifier (input/output configuration program). channel wrap test A diagnostic procedure that checks S/390 host-to-Director or host-to-Switch connectivity by returning the output of the host as input. The test is host-initiated and transmits Fibre Channel frames to a Director or Switch port. A Director or Switch port enabled for channel wrapping echoes the frame back to the host. CHP See channel path. CHPID See channel path identifier.

(1) Pertaining to direct attachment of devices by data I/O channels to a computer. (2)

Pertaining to devices attached to a control unit by cables, not telecommunication lines (D).

Synonymous with

channel path

CHP. A single interface between a central processor and one or more control units, along

which signals and data are sent to perform I/O requests (D).

channel path identifier

CHPID. In a channel subsystem, a value assigned to each channel path of the system that

uniquely identifies the path (D). See also

channel-to-channel

(channel-to-channel)

(input/output configuration program).

channel subsystem

CSS. A collection of subchannels that direct the flow of information between I/O devices and

main storage, relieve the processor of communication tasks, and perform path management

functions (D).

channel-to-channel

CTC. A channel attached to another channel (channel-to-channel) and specifies the I/O mode

of operation for the channel path under the I/O configuration program (IOCP) channel path

identifier (CHPID) statement ‘Type’ parameter (D). See also

channel path identifier

(input/output configuration program).

channel wrap test

A diagnostic procedure that checks S/390 host-to-Director or host-to-Switch connectivity by

returning the output of the host as input. The test is host-initiated and transmits Fibre Channel

frames to a Director or Switch port. A Director or Switch port enabled for channel wrapping

echoes the frame back to the host.
