122 Alphabetical list of commands
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.

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

write-through when CompactFlash memory fails.

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 to 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.
