System and method for processing commands in a storage enclosure

A method for managing the handling interrupts in a storage enclosure, wherein the storage enclosure includes first and second storage enclosure processors, each of which is coupled to a first expander module associated with the first storage enclosure processor and a second expander module associated with the second storage enclosure processor, comprising:

• monitoring the operational status of each of the first and second storage enclosure processors;
• receiving an interrupt issued by the first expander module or the second expander module at each of the first storage enclosure processor and the second storage enclosure processor,
• masking off at each of the first storage enclosure processor and the second storage enclosure processor interrupts issued by the expander module associated with the other storage enclosure processor, and
• if it is determined that one of the first storage enclosure processor or the second storage enclosure processor is not operational, unmasking at the operational storage enclosure processor interrupts issued by the non-operational storage enclosure processor.

A storage enclosure, comprising:

• a first command port;
• a second command port;
• a first storage enclosure processor;
• and
• a second storage enclosure processor;
• wherein a first command line is coupled between the first command port and each of the first storage enclosure processor and the second storage enclosure processor;
• wherein a second command line is coupled between the second command port and each of the first storage enclosure processor and the second storage enclosure processor;
• wherein a command transmitted by either the first command port or the second command port is received by each of the first storage enclosure processor or the second storage enclosure processor.
