Apparatus, system, and method for facilitating port testing of a multi-port host adapter

An apparatus for facilitating port testing of a multi-port host adapter, the apparatus comprising:

• an initiation module configured to send a multi-port test request to a controller of the multi-port host adapter, the multi-port test request identifying one or more ports of the multi-port host adapter for a port test routine, the controller comprising
• a scheduler configured to schedule execution of a plurality of threads to implement the port test routine, the threads comprising independent executable segments and
• a multithreading module configured to provide multithreaded execution of the plurality of threads such that the port test of one port and the port test of any additional ports of the multi-port host adapter are performed in parallel;
• a confirmation module configured to receive an acknowledgment from a port test module of the controller, the port test module configured to acknowledge the multi-port test request;
• a polling module configured to end a communication session with the controller, to send periodic status inquiries, and to process status report messages from the controller.

A system for facilitating port testing of a multi-port host adapter, comprising:

• a control processor configured to manage and control data processing in the system;
• a host adapter configured to communicate with a host over a network, the host adapter comprising a plurality of ports;
• a test module configured to execute a port test routine simultaneously on two or more ports of the host adapter, the test module comprising a scheduler configured to schedule execution of a plurality of threads to test at least two ports of the host adapter, the threads comprising independent executable segments of a port test routine, and
• a multithreading module configured to provide multithreaded execution of the plurality of threads such that the port test of the at least two ports an I/O processing continuing on any untested ports are performed in parallel;
• and
• a testing interface configured to communicate with the test module to initiate port tests and report results of port tests.

A computer program product comprising a computer readable storage medium having computer readable program code executable to perform operations to facilitate port testing of a multi-port host adapter, the operations comprising:

• dividing a port test routine into a plurality of threads, each thread comprising a segment of the routine;
• scheduling execution of the plurality of threads to test a first port and a second port of the multi-port host adapter, the test represented by the port test routine;
• and
• multithreading execution of the plurality of threads such that the port test of the first port and the port test of the second port are performed in parallel.

A method for facilitating port testing of a multi-port host adapter, the method comprising:
