IBM System Storage DS3500: Introduction and Implementation Guide
If the logical drive contains critical data, you can set a high modification priority to keep the
time of a critical state (for example, after losing a disk) as short as possible, even if this affects
the system performance during the modification process.
The following modification priority rates are available:
򐂰 Lowest
򐂰 Low
򐂰 Medium
򐂰 High
򐂰 Highest
To change the modification priority, perform the following steps:
1. Select a logical drive, right-click it, and select Change

Modification Priority.
2. Make sure that the correct logical drive is selected, and set the new Modification Priority
value, as shown in Figure 9-26.

3. Click OK and then Yes in next window to confirm this change.
4. You will then see the completion window as shown in Figure 9-27

Note: The lowest priority rate favors system performance, but the modification operation
takes longer. The highest priority rate favors the modification operation, but system
performance might be compromised.
