2. To create an array automatically, click One-click Create.
NOTE!
 There is no need to select disks when creating an array with One-click
Create. The system identifies all usable disks. RAID 1 is created when
two disks are available. When three or more disks are available, RAID
5 is created. If more than four disks are available, a global hot spare
disk will be created.
 Arrays created in this way are named ARRAYX, for example, ARRAY1,
ARRAY2.
3. To create an array manually, select the desired disks and then click
Create. In the window displayed, enter the array name, select the
array type, and select local disks. Click OK to complete the setup.
Note that no hot spare disk will be created automatically. Make sure
all disks are selected to create array(s); otherwise, disk space will be
wasted (because disks that are not selected will not be used for
storage).
Rebuilding an Array
By checking array status you can determine whether maintenance is
necessary.
NOTE!
To be alerted when an array is degraded or damaged, you can configure
alarm-triggered action at Alarm > Alert.
An array is in one of four statuses: normal, degraded, damaged, rebuild.
The status is normal if no physical disk is lost. When the number of
physical disks lost reaches the specified value, the array is considered
damaged. The status between normal and damaged is degraded. A
degraded array can be recovered to normal status through rebuilding.
