This INTEGER indicates whether ClusterXL has actively verified (health-checked) the state of this monitored interface, as opposed to merely assuming it based on link state. An interface that reports up but isn't actually verified might still be silently failing at a layer ClusterXL's basic check doesn't probe, so this flag tells an admin how much to trust the accompanying haStatus value. If haStatus says OK but haVerified indicates no active verification occurred, that status should be treated with more caution than a fully verified one.
