ABSTRACT:
Methods and apparatuses for facilitating the management of multiple controller code versions for implementing operational aspects of storage system controllers are provided. In particular, multiple versions of storage controller code are loaded into the physical memory of a storage controller. The logical region in which a particular controller code version is loaded may be designated in metadata as a primary, secondary or other region. The controller code that is associated with a logical version designated as the primary region is selected by the storage controller for execution upon a storage controller reboot. Accordingly, time consuming copy operations are not required in order to switch between different versions of storage controller code.
