AEC-6896S/6896 Manual

3.2.2 Mirror Mode

This mode needs a pair of hard drives for each array. If the two hard drives you have
chosen contain the same data, or different data that you don't want to keep, you can
select "Create Only". But if not, please choose one of them as the source hard drive
(label is disk0 or disk1), and copy the data from the source one to another.
Figure 3-6
When one of the hard drives in mirror array is damaged, you have to power off, then
change the bad hard drive. Upon booting anew, the screen will prompt you to use
"Build Mirror Disk" in BIOS to rebuild. Please notice that if you connect the newly
removed hard drive back to AEC-6896, in the channel display area at the bottom of
BIOS screen, the hard drive will be added to a new array (its number is different
from the original mirror array). After choosing "Build Mirror Disk", you will find the
prompt: problem mirror array as shown below. If you want to update the hard drive's
contents in the array, click 1 to change to Non RAID, then combine it with another
correct hard drive into Mirror Array according to the instructions on the screen. If
you want to reserve the hard drive's contents, click 2 to cancel the RAID setting so
as to add the array you want to reserve.
