Abstract
A method and system for load balancing. The method includes determining that connectivity between a first host and a primary array controller of a storage system has failed. The first host is configured to send input/output messages (I/Os) to a storage system through a storage network fabric. An available host is discovered at a multi-pathing driver of the first host. The available host is capable of delivering I/Os to the primary array controller. An I/O is redirected from said first host to the available host over a secondary communication network for delivery to the storage system.
