set auto-write-through-trigger Description Sets the trigger conditions that cause the controller to change the cache policy from write-back to write-through. You can set multiple triggers. By default super-cap-failure and auto-write-back are enabled. Alias: set awt. When the cache mode is changed, an event is logged. Syntax set auto-write-through-trigger [controller-failure enabled|disabled|on|off] [super-cap-failure enabled|disabled|on|off] [compact-flash-failure enabled|disabled|on|off] [power-supply-failure enabled|disabled|on|off] [fan-failure enabled|disabled|on|off] [temperature-exceeded enabled|disabled|on|off] [partner-notify enabled|disabled|on|off] [auto-write-back enabled|disabled|on|off] Parameters controller-failure enabled|disabled|on|off If the cache policy is set to write-back, specify whether the policy automatically changes to write-through when a controller fails. super-cap-failure enabled|disabled|on|off If the cache policy is set to write-back, specify whether the policy automatically changes to write-through when cache backup power is not fully charged or fails. compact-flash-failure enabled|disabled|on|off If the cache policy is set to write-back, specify whether the policy automatically changes to write-through when CompactFlash memory fails. power-supply-failure enabled|disabled|on|off If the cache policy is set to write-back, specify whether the policy automatically changes to write-through when a power supply fails. fan-failure enabled|disabled|on|off If the cache policy is set to write-back, specify whether the policy automatically changes to write-through when a fan fails. temperature-exceeded enabled|disabled|on|off Specify whether to force a controller shutdown if a temperature is detected that exceeds system threshold limits. partner-notify enabled|disabled|on|off Specify whether to notify the partner controller that a trigger condition occurred. Enable this option to have the partner also change to write-through mode for better data protection. Disable this option to allow the partner continue using its current caching mode for better performance. auto-write-back enabled|disabled|on|off Specify whether the cache mode automatically changes to write-back after the trigger condition is cleared. Example Enable the controller-failure trigger and disable the partner-notification trigger: # set auto-write-through-trigger controller-failure enabled partner-notify disabled Success: Command completed successfully. - Auto-write-through-trigger parameters were changed.
