Parameters
auto-stall-recovery enabled|disabled|on|off
Optional. Detects situations where a controller stall is preventing I/O operations from completing, and
recovers the system so that at least one controller is operational, thus avoiding data-unavailability
situations. This feature focuses on failover/recovery stalls. When a stall is detected, event 531 is
logged.
● disabled or off: Auto stall recovery is disabled. The system will constantly perform auto stall
detection in the background but will not automatically perform recovery actions.
● enabled or on: Auto stall recovery is enabled. The system will constantly perform auto stall
detection in the background and automatically perform recovery actions. This is the default.
