摘要： A method to adjust a multi-path device reservation by supplying a computing device and a storage controller interconnected with a communication link. The method further reserves a data storage device in communication with the storage controller, where that data storage device reservation is held by a first communication path group comprising a first plurality of communication paths configured in the communication link. If the method detects a failed communication path configured in the first communication path group, the method configures a second communication path group by removing the failed communication path from the first communication path group, wherein the second communication path group maintains the data storage device reservation.

摘要： A method to maintain write operation atomicity where a write operation crosses a data storage medium track boundary. The method supplies a storage controller comprising a host adapter, a processor, and a NVS. The primary host adapter receives from a host computer a write request and data. The method determines if the write request will cross a data storage medium track boundary. If the write request will cross a data storage medium track boundary, the method indicates to the host adapter that the write request comprises a two-track transfer, and writes the data to the primary NVS as the data is received. If the host computer fails prior to providing all the data to the storage controller, the method discards the data written to the NVS to ensure write operation atomicity.
