Appendix D: Adaptec HostRAID Setup
Assigning Array Properties
Once a new array is completed, you can assign properties to the array.
Caution: Once the array is created and its properties are assigned, and you can- not change the array properties using this utility.
To assign properties to the new array:
1.In the Array Properties menu (as shown in the screen below), select an array type and press Enter. Only the available array types will be displayed on the screen. (*RAID 0 or RAID 1 requires two drives.)
2.Under the item "Arrays Label", type in a label and press <Enter>. (Note: The label shall not be more than 15 characters.)
3.For RAID 0, select the desired stripe size. (*Note: Available stripe sizes are 16, 32, and 64 KB. 64K is default. Please do not change the default setting.)
4.The item: "Create RAID via" allows you to select between the different ways of creating methods for RAID 0 and RAID 1.
The following table gives examples of when each is appropriate.
