Systems, methods, apparatus and software can combine information about host access to virtualization functionality and virtualization functionality access to storage, use this information in decisions pertaining to high availability of virtualization in an SAN. Upon detection of the partitioning of a SAN fabric, accessibility information is gathered. That information is analyzed to uncover potential failover scenarios, orchestrate such failovers, and in some cases select best case solutions from among several possible solutions based on access prioritization criteria (e.g., defined priority, maximum access, maximum I/O, etc.).
