Abstract:
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.
