Abstract

Disclosed is a method for an I/O adapter (IOA) to emulate the Skip Write function. This emulation is performed transparent to the operating system software while minimizing any performance degradation vs Disk Drive implemented Skip Write function.

The requestor provides: a starting block address a length count of the number of blocks to write
