9-3
The default setting is 1% backoff. This default allows you to easily work with drives
that have the same nominal capacity, but different actual capacities. The backoff
percentage affects all arrays created on the controller after you set the percentage.
If the drives in an array are not equal in size, the array capacity in a RAID-5 array is
based on the smallest member’s capacity. The backoff percentage is then backed off
the capacity from that amount.
To change the backoff percentage:
1
From the System Menu, select
Configuration Menu
and press
Enter
.
The Configuration Menu displays.
2
Select
Backoff Percent
and press
Enter
.
The Backoff Percent screen displays.
3
Enter the backoff percent you want to use and press
Enter
.
Enter the percentage as three digits in the following format: 00.0%. The default
is 01.0%.
