Issue

  • Call home for switchover vetoed is seen but no switchover is attempted:

Call home for METROCLUSTER SWITCHOVER VETOED
  • Errors seen showing all nodes are online:

Node_1 (overridable veto): Both DR partner nodes are online. Either shut down the remote nodes manually, then try the command again, or use the "-override-vetoes" parameter to force the remote nodes to shut down.
  • Audit logs show no CLI commands were ran.
  • Tiebreaker logs show no switchover attempts.
  • MGWD logs show API calls for switchover on disaster:

ERR: metrocluster::PATCH: MCC patch: action 1 (switchover) specified 
NOTICE: metrocluster::PATCH: REST SO; forcedOnDisaster: yes, dryRun: no, controllerReplacement: no
