Communication with input/output system devices

A system for procuring information from entities in a network via an Input/Output (I/O) processing system, the system comprising:

• a channel subsystem for communication with an I/O operating system and the network entity, the channel subsystem configured to perform a method comprising:
• obtaining, by the channel subsystem, a transport command word (TCW) specified by an operating system, the TCW comprising an address of a transport services request block (TSRQB) and an address of a transport services response block (TSRSB);
• obtaining, by the channel subsystem, the TSRQB;
• building, by the channel subsystem, at least one command request based on the TSRQB, and sending, by the channel subsystem, the at least one command request from the channel subsystem to at least one network entity, the at least one command request including at least one of a fibre-channel generic services (FC-GS) request, a fibre-channel link services (FC-LS) request, and a fibre-channel link-level function (FC-SB) request;
• receiving, by the channel subsystem, a response to the at least one command request from the at least one network entity;
• and
• storing, by the channel subsystem, the response to the TSRSB based on the address of the TSRSB obtained from the TCW.

A computer-implemented method for procuring information from entities in a network via an Input/Output (I/O) processing system, comprising:

• obtaining, by a channel subsystem, a transport command word (TCW) specified by an operating system, the TCW comprising an address of a transport services request block (TSRQB) and an address of a transport services response block (TSRSB);
• obtaining, by the channel subsystem, the TSRQB;
• building, by the channel subsystem, at least one command request based on the TSRQB, and sending, by the channel subsystem, the at least one command request from the channel subsystem to at least one network entity, the at least one command request including at least one of a fibre-channel generic services (FC-GS) request, a fibre-channel link services (FC-LS) request, and a fibre-channel link-level function (FC-SB) request;
• receiving, by the channel subsystem, a response to the at least one command request from the at least one network entity;
• and
• storing, by the channel subsystem, the response to the TSRSB based on the address of the TSRSB obtained from the TCW.
