-# Turn off disk's enclosure slot if an I/O is hung triggering the deadman.
-#
-# It's possible for outstanding I/O to a misbehaving SCSI disk to neither
-# promptly complete or return an error.  This can occur due to retry and
-# recovery actions taken by the SCSI layer, driver, or disk.  When it occurs
-# the pool will be unresponsive even though there may be sufficient redundancy
-# configured to proceeded without this single disk.
-#
-# When a hung I/O is detected by the kmods it will be posted as a deadman
-# event.  By default an I/O is considered to be hung after 5 minutes.  This
-# value can be changed with the zfs_deadman_ziotime_ms module parameter.
-# If ZED_POWER_OFF_ENCLOSURE_SLOT_ON_DEADMAN is set the disk's enclosure
-# slot will be powered off causing the outstanding I/O to fail.  The ZED
-# will then handle this like a normal disk failure and FAULT the vdev.
-#
-# We assume the user will be responsible for turning the slot back on
-# after replacing the disk.
-#
-# Note that this script requires that your enclosure be supported by the
-# Linux SCSI Enclosure services (SES) driver.  The script will do nothing
-# if you have no enclosure, or if your enclosure isn't supported.
-#
-# Exit codes:
-#   0: slot successfully powered off
-#   1: enclosure not available
-#   2: ZED_POWER_OFF_ENCLOSURE_SLOT_ON_DEADMAN disabled
-#   3: System not configured to wait on deadman
-#   4: The enclosure sysfs path passed from ZFS does not exist
-#   5: Enclosure slot didn't actually turn off after we told it to
