Interconnect path failover

A system for interconnect failover between a primary storage controller and a secondary storage controller, comprising:

• an interconnect failover module configured to:
• identify a failover trigger associated with a first interconnect path between a primary storage controller and a secondary storage controller;
• send a fence instruction to the secondary storage controller, the fence instruction instructing the secondary storage controller to fence I/O operations from the first interconnect path;
• receive a fence acknowledgement message from the secondary storage controller;
• and
• perform interconnect failover for the first interconnect path utilizing a second interconnect path to transmit storage information from the primary storage controller to the secondary storage controller.

A computer readable medium comprising instructions that when executed perform a method for interconnect failover between a primary storage controller and a secondary storage controller, comprising:

• identifying a failover trigger associated with a first interconnect path between a primary storage controller and a secondary storage controller;
• sending a fence instruction to the secondary storage controller, the fence instruction instructing the secondary storage controller to fence I/O operations from the first interconnect path;
• receiving a fence acknowledgement message from the secondary storage controller;
• and
• performing interconnect failover for the first interconnect path utilizing a second interconnect path to transmit storage information from the primary storage controller to the secondary storage controller.
