Storage system upgrade

Example embodiments of the present invention relate to a method, an apparatus, and a computer program product for updating disk geometry in a multipathing environment. The method includes receiving a disk geometry update for a logical unit on a storage array accessible via a multipathing device in the multipathing environment. The method then includes translating the disk geometry update for the logical unit for each respective disk device aggregated by the multipathing device. Requests for the logical unit then may be issued according to the updated geometry.
