Abstract
The present invention relates to communications methods and apparatus for detecting and/or mitigating split brain occurrences in high availability systems. A split brain condition being a condition wherein both a standby processing node and another processing node of a cluster of processing nodes included in a high availability system are both operating at the same time in an active mode of operation. An exemplary method embodiment of operating a high availability system including a plurality of processing nodes includes the steps of determining at a standby processing node that a failure condition exists, said standby processing node being one of the cluster of processing nodes; switching the standby processing node from a standby mode of operation to an active mode of operation in response to determining that a failure condition exists; and determining whether the high availability system is experiencing a split brain condition.
