摘要： Provided are a computer program product, system, and method performing an atomic write operation across multiple storage devices. A determination is made of a plurality of storage devices on which to write data for a write operation. A tag is generated to uniquely identify the write operation. A write command is sent to each of the determined storage devices including the tag and write data to cause each of the storage devices to write the write data at the storage device. Each of the storage devices maintains a copy of a previous version of the data to be updated by the write operation. A revert command is sent with the tag to one of the storage devices to cause the storage device to restore the copy of the previous version of the write data at the storage device.
