Changing a volume's cache settings

CAUTION:
• Only disable write-back caching if you fully understand how the host operating system, application,
and adapter move data. If used incorrectly, you might hinder system performance.
• Only change read-ahead cache settings if you fully understand how the host operating system,
application, and adapter move data so that you can adjust the settings accordingly.
To change a volume's cache settings
1. In the Configuration View panel, right-click a volume and select Configuration > Modify Volume Cache
Settings.
2. In the main panel, set the read-ahead cache options:
• Write Policy. Select write-back or write-through. The default is write-back.
