1. Click the Create Array button. The Create Drive Array screen appears.

Figure 6-4. Create Drive Array screen

Always group physical drives of the same size. If you mix drive sizes, the capacity

of the larger drives is wasted.

Select the three drives you want to make up the array from the drives on

the left. For this example, the following drives were selected:

q Port 1:SCSI ID 0

q Port 1:SCSI ID 1

q Port 1:SCSI ID 2

2. Click the Assign Drive(s) to Array button.

Given the reliability of a particular generation of hard drive technology, the

probability of an array experiencing a drive failure increases with the number of drives in

an array. Compaq recommends that you limit the number of drives in an array to 14.
