Patent ID: 7487403

Claim:
A method, comprising: intercepting, with a module, a signal indicating a failure of a path in a fabric providing a connection to a shared device; generating, with the module, an interrupt to a device driver in an operating system providing an interface to the shared device that is inaccessible due to the path failure; requesting, with the device driver, information from the module on a status of a plurality of devices that are not accessible due to the path failure; receiving, by the device driver, information indicating the inaccessible device; reconfiguring, by the device driver, to discontinue use of the inaccessible device; managing, by the module, operations of multiple logical partitions each executing a separate operating system and device driver interfacing to the devices; and determining, by the module, a logical partition assigned to the inaccessible device from an assignment of logical partitions to devices in response to the signal, wherein the interrupt is sent to the device driver in the determined logical partition.
