an ICKDSF CONTROL command to reset the fenced condition to one of
the devices attached to the fenced interface.
- If no online paths remain to the device, do the following:
- VARY FORCE the devices attached to the interface offline.
- Cancel all jobs that are using the device.
- Vary online at least one path to the device.
- Vary the device online, making sure that no jobs allocate the
