Using Adaptec RAID Configuration
Assigning Array Properties
Note that you cannot change array properties from the ACU once
the array is created. To change array properties once the array is
created, use Adaptec Storage Manager.
To assign properties to the new array:
1 In the Array Properties menu, select an array type and press
Enter. Note that only those array types available according to
the number of drives selected are displayed. For a description of
the supported array types, see the installation guide shipped
with your controller.
The physical SCSI limitation for the controller is 15 drives per
channel. The maximum number of drives allowed and
minimum number of drives required depends on the RAID
level. Consult Table 2-1 for a listing of this information.
2 Type in an optional label for the array and press Enter.
3 Enter the desired array size. The maximum array size available
based on the segments you selected is displayed automatically.
If you want to designate a different array size, type the desired
array size and select MB (megabytes), GB (gigabytes), or TB
(terabytes) from the drop-down list. If the available space from
the selected segments is greater than the size specified, the
remaining space will be available for use in other arrays.
