Abstract
An example computer-implemented method for performing failover operations in a data storage system is described herein. The data storage system can include a first storage controller and a second storage controller for processing input/output ('I/O') operations for the data storage system. The method can include, in response to a failure of the first storage controller, performing failover operations with the second storage controller, and processing the I/O operations with the second storage controller. The failover operations can include preparing a disk subsystem layer for I/O operations, preparing a device manager layer for the I/O operations, and preparing a network layer for the I/O operations. The disk subsystem, device manager, and network layers can be prepared for the I/O operations without dependencies. In particular, preparation of the network layer is not dependent on preparation of the disk subsystem layer or the device manager layer.
