Abstract
For efficient handing of semi-asynchronous RAID write failures using a processor device in a computing environment, a write operation is committed on a primary copy of data on a primary entity while sending the data to a secondary entity while awaiting an acknowledgment by the secondary entity. The acknowledgment indicates to the primary entity that metadata for the write operation has arrived at the secondary entity without necessarily indicating the data has arrived at the secondary entity.
