Abstract: A path selection module selects at least two fiber channel paths between a fiber channel host and a fiber channel destination. A trace route module performs one or more fiber channel trace route procedures for each of the at least two fiber channel paths. The trace route module provides a set of fiber channel links between the fiber channel host and the fiber channel destination for each of the at least two fiber channel paths. A record registration module registers with one or more event servers to receive link incident records for the fiber channel links in the sets of fiber channel links.

Abstract: An apparatus, system, and method are disclosed for communicating over multiple paths. A reserve interception module intercepts a single-path reserve command from a host. The host-computing environment is configured to issue single-path commands, but is not configured to issue multiple-path commands. A reserve generation module generates a multiple-path reserve command in response to the single-path command. A reserve command module reserves multiple paths between the host and the storage device using the multiple-path command, enabling the host to communicate over multiple paths with the storage device.

Abstract: A method and system for path management of data processing in an environment which includes a plurality of hosts running multiple operating systems is disclosed. The method and system includes providing a portable path management code and providing a plurality of control modules. Each of the control modules has an area which can only be accessed by the portable path management code. The method and system also include providing an interface to at least one device driver from the portable management code to allow the portable management code to control access to plurality of paths to a plurality of storage subsystems by the at least one device driver. The method and system in accordance with the present invention can provide path load balancing and fail over for a plurality of paths to a plurality of storage subsystems. The path management code is portable and platform independent so that the functionality can be ported easily to each operating system in the multiple system environment.
