Abstract
A single hardware I/O control block is used to efficiently abort a target I/O command for a target I/O device, e.g., one target I/O device in a plurality of target I/O devices. The abort command is included in the same hardware I/O control block that specified the target I/O command to be aborted. Execution of both the target I/O command and the abort command returns only one hardware I/O control block pointer and generates only one interrupt to a host system when both the target I/O command and the abort command are completed. All time relationships between the execution of the abort command and execution of the original target I/O command are supported. There are no holes where the abort command is lost or where the host system is advised of target I/O command completion prematurely, or is not advised of completion at all.
