What does AUSO stand for in MetroCluster operations?

• A. Automatic Unplanned System Operation
• B. Automated Unplanned Switchover
• C. Auto Unplanned System Operation
• D. Automatic Unplanned Switchover

Answer: (D)

Automatic Unplanned Switchover describes the automatic failover process in MetroCluster when a failure at the primary site prevents normal I/O, prompting the system to promote the remote site to active without human intervention. This keeps data accessible by switching operations to the mirrored partner, preserving uptime during unexpected outages. The term emphasizes three things: automatic execution (no manual steps required), unplanned nature (triggered by a fault rather than maintenance), and switchover (the process of switching the active site). The other phrasings don’t fit because they either replace Switchover with System Operation or use alternate wording (Automated/Auto) that isn’t the standard terminology for this specific automatic failover mechanism.
