– Integrated Striping (IS) (also known as RAID 0)
Use this option to create an integrated striping array of two to eight disks. All
data on the array disks will be deleted.
v
Hard disk drive capacities affect how you create arrays. The drives in an array
can have different capacities, but the RAID controller treats them as if they all
have the capacity of the smallest hard disk drive.
v
If you use an integrated SAS/SATA controller with RAID capabilities to configure
a RAID 1 (mirrored) array after you have installed the operating system, you will
lose access to any data or applications that were previously stored on the
secondary drive of the mirrored pair.
v
If you install a different type of RAID controller, see the documentation that
comes with the controller for information about viewing and changing settings for
attached devices.

Formatting a hard disk drive
Low-level formatting removes all data from the hard disk. If there is data on the disk
that you want to save, back up the hard disk before you perform this procedure.
Note:
Before you format a hard disk, make sure that the disk is not part of a
mirrored pair.
To format a drive, complete the following steps:
1. From the list of adapters, select the controller (channel) for the drive that you
want to format and press Enter.
2. Select
SAS Topology
