To assign properties to the new array:
1
In the Array Properties menu, select an array type, then press
Enter
.
Only the available array types, RAID 0, 1, and 10 are displayed. RAID 0 and 1 requires two
to four drives. RAID 10 requires a minimum of four disk drives.
2
Optional
:
Type a label of no more than 15 characters for the array, then press
Enter

For RAID 0, select the desired stripe size. Available stripe sizes are 16, 32, and 64 KB
(default).
Note:
It is recommended that you do not change the default.

The options under
Create RAID Via
allows you to select between the different creation
methods for RAID 0, 1, and 10. The following table gives examples of when each is
appropriate.
Note:
●
Before adding a new drive to an array, back up any data contained on the new drive.
Otherwise, all data will be lost.
●
Only disk drives that were previously configured as simple volumes can be used for
RAID 0 or 1 migration when the single/source drive has data on it. See
Configuring
Disk Drives
on page 56
to create a simple volume.
●
If you stop the build or clear process on a RAID 1 from ACU, you can restart it by
pressing
Ctrl+R
.
●
A RAID 1 and 10 created using the Quick Init option may return some data
miscompares if you later run a consistency check. This is normal and is not a cause for
