Description
If a disk has been replaced with a disk that has been used in another enclosure, the
status of the replacement disk is LEFTOVER instead of OK. The disk cannot be used until
it has been cleared. Use this button to clear the disk. (If you attempt to use this button
with a clean disk, no action is taken.)
Use this button to turn the Beacon LED of the selected disk on. This makes it easier to
identify a failed or failing disk in an enclosure for replacement.
Use this button to turn the Beacon LED of the selected disk off.
