Abstract
Error handling and recovery, implemented in a storage server, detects an error in a peripheral device of the storage server. If the error is recoverable, the system contains the error by isolating the peripheral device to prevent the generation of additional interrupt signals and migrates operations of the peripheral device to a back-up peripheral device. The system initiates error recovery by calling a recovery routine and a reinitialization routine, both provided by a device driver for the peripheral device. After device recovery is complete, the system migrates operations of the back-up peripheral device back to the peripheral device.
