Spare
Option
With
a spare disk, you can enhance the security of RAID 1 (or
RAID 0/1, if supported) array . If one
of the disks in the array fails, the spare disk will automatically take it over.
You
can open the Edit Spare window to add or remove spare disk(s). If
your RAID controller supports spare pool, you can add or remove one or
more spare disk(s). There are
three ways to open the Edit Spare window.
1.
Right-click on the device item in the array tree will pop up a menu. Select Edit
Spare on the menu.
2.
Click the menu Configuration->Edit Spare.
3. Click
the Spare button on the tool bar.
