If ZED_POWER_OFF_ENCLOUSRE_SLOT_ON_FAULT is enabled in zed.rc, then power off the drive's slot in the enclosure if it becomes FAULTED. This can help silence misbehaving drives. This assumes your drive enclosure fully supports slot power control via sysfs.

The statechange-slot_off.sh zedlet which was added in openzfs#15200 needed to be installed so it's included by the packages. Additional testing has also shown that multiple retries are often needed for the script to operate reliably.
