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, if you don't have an HDD
cabinet for Hot Swap, you have to power off, then change the hard drive. Upon
booting anew, the screen will prompt you to use "Build Mirror Disk" in BIOS to re-
build. Please notice that if you connect the newly removed hard drive back to AEC-
6885, 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 to Mirror Array accord-
ing to the instructions on the screen. If you want to reserve the hard drive's con-
tents, click 2 to cancel the RAID setting so as to add the array you want to reserve.
