1. In the Array Properties menu, select an array type and press Enter. Note that only the
available array types, RAID 0 and RAID 1, are displayed. Each of these types requires
two drives.
2. Type in an optional label for the array and press Enter.
3. For RAID 0, select the desired stripe size. Available stripe sizes are 16KB, 32KB and
64KB (default)
4. Create RAID via allows you to select between the different creation methods for RAID 0
and RAID 1. The following table gives examples of when each is appropriate.
RAID level
RAID 0 No Init
RAID 0 Migrate*
RAID 1 Build*
RAID 1 Clear
RAID 1 Quick Init
* If you select Migrate for RAID 0, or Build for RAID 1, you will be asked to select the
source drive. The contents of the source drive will be preserved. However, the data
on the new drive will be lost.
Before adding a new drive to an array, back up any data contained on the
new drive. Otherwise, all data will be lost.
A RAID 1 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 caus e for concern.
The Adaptec RAID Configuration Utility allows you to use drives of different
sizes in a RAID 1. If you choose the smaller drive as the second drive, you
will be warned about the risk of data loss.
Do not interrupt the creation of a RAID 0 using the Migrate option. If you
do, there is no way to restart and no way to recover the data that was on
the source drive.
When you are finished, press Done.
Chapter 4: SATA/RAID Setup (for SATA RAID model)
Create RAID via
Creating a RAID 0 on new drives.
Creating a RAID 0 from one new drive and one
drive with data you wish to preserve.
Any time you wish to create a RA ID 1, but
especially if you have data on one drive that you
wish to preserve.
Creating a RAID 1 on new drives, or when you
want to ensure that the array contains no data after
creation.
Fastest way to create a RAID 1. Appropriate when
using new drives.
