\r\nThe majority consensus algorithm requires that \r\nyou create at least three state database replicas before you build or \r\ncommit any metadevices. To reach a consensus, at least two of the three \r\nreplicas must be available. \r\nThe majority consensus algorithm: \r\n● Makes sure that the system stays running if at least half of the state \r\ndatabase replicas are available. \r\n● Causes the system to panic if fewer than half of the state database \r\nreplicas are available. \r\n● Prevents the system from starting the Solaris Volume Manager \r\nsoftware unless a majority of the total number of state database \r\nreplicas are available. \r\n
