3.1.2 Hot Spares
Hot Spares can be setup so that if your RAID fails the hot spare will automatically be rebuilt into your
RAID. If you can spare the capacity, WiebeTech recommends creating a hot spare for data backup. To
create a hot spare select the “Hot Spares” tab on the ATTO Configuration Tool. Right click in the empty
section on the bottom of the tool. Select “New Hot Spare”. Now simply drag the drive you want to use as
a hot spare into the empty area.

4.1.2 Using Volumes
When you connect the unit to the Mac for the first time and turn on the power, you’ll
probably see a message saying that the disk is unreadable. This is because you
must format the volume before using it. The easiest way to do this is to use Mac OS
X’s Disk Utility. If you plan to use the unit on both Macs and PCs, select “MS DOS
File System” as the format type. If you only plan to use the unit on Macs, then select
“Mac OS Extended”. After the volume is formatted, an icon representing the drive
volume will appear (“mount”) on the desktop. You can now use the volume just like
an internal hard drive.
Eject the volume before powering down the unit by dragging the volume’s icon to the trash bin, or by
selecting the volume then pressing Command-E. Shutting down the unit without first ejecting the volume
can result in data loss.
