Abstract
A request is received to upgrade firmware of a set of disk array enclosures (DAEs) in a storage system. Each DAE is chained to another DAE by first and second chains. The first chain provides an active path from a host server to the DAEs. The second chain provides a secondary path from the host server to the DAEs. A determination is made as to whether the secondary path is operational. If the secondary path is operational, data of the active path is failed over to the secondary path, the active path now being an inactive path. Firmware along the inactive path is upgraded. If the secondary path is not operational, the request to upgrade firmware is denied.
