IMPORTANT: If a demo license key expires, all SmartCache volumes configured with write-back
cache write policy are converted to write -through. When this happens, the logical drive details
show different values for Cache Write Policy and Cache Write Policy Requested. If the license is
reinstalled, the SmartCache volumes are restored to their original write-back cache write policy.
To modify the logical drive cache policy settings:
1. Open HP SSA.
For more information, see "Using the HP SSA GUI (on page 17)."
2. Select the controller.
3. Click Modify Controller Settings.
4. Under Physical Drive Write Cache State, select one of the following:
o Enabled
o Disabled
5. Click Save Settings.
6. A summary page appears. Click Finish to exit.
