  • MetroCluster
  • Cluster shut down due to overtemperature issue
  • Automatic Unplanned Switchover (AUSO) not triggered

Answer

  • Shut down caused by overtemperature is classified as environmental shutdown, which is considered a graceful, and AUSO is not triggered
  • AUSO will only be triggered if the storage at the disaster site is accessible.
  • AUSO functionality can be achieved by using a functional third site arbitrary solution like Tiebreaker or ProLion Solution
