Abstract

A method, apparatus and program product are provided for moving data from a source memory zone to a target memory zone of a computer. A source host operating system invokes a synchronous multiple move command for SBAL output buffers with a common target zone. The machine firmware identifies and validates the target argument of the first SBAL, validates the target zone state, moves the data associated with the first SBAL to the target zone; and then iteratively moves the data associated with the remaining SBALs to the target zone.
