An apparatus, system, and method are disclosed for providing a network interface to a small computer system interface ('SCSI') storage device driver. The method includes detecting an event in one of a storage device and a SCSI device driver of the storage device and comparing an event identifier associated with the event to a list of event identifiers. The method includes suspending an application in communication with the storage device through the SCSI device driver and sending a request associated with the event to a remote event manager over a transaction control protocol/Internet protocol ('TCP/IP') connection, each in response to the event identifier matching a listed event identifier. The method includes receiving a response related to the event from the remote event manager over a TCP/IP connection. The method includes resuming the application after sending the response to the storage device through the SCSI device driver or failing the application.

Apparatus, system, and method for extending a device driver to facilitate a network connection to a remote event manager

Provided are a method, system, and program for selecting a path to a device to use when sending data requests to the device. Data requests are submitted to the device on a first path. Device information is maintained indicating a position of a data transfer mechanism of the device that performs the submitted data request. A second path to the device is selected if the first path fails. Data requests are submitted to the indicated position at the device on the selected second path.
