Managing Arrays To see whether the cache is working, you can check the status and change the properties in the Array Properties dialog box, Cache tab. When you perform a normal system shutdown, the controller automatically writes all data in the write cache to disk before the shutdown. To change the write cache properties: 1 In the System Browser window, select the array whose cache settings you want to change. 2 Click Properties. The Array Properties dialog box appears. 3 Click the Cache tab. 4 Select the new cache options you want. - Write Back-Turns on write cache. Caution: If your controller does not have a battery or if it is not charged, you risk losing data by selecting this option. - Write Through-Turns off write cache; however, the data written to the array is still stored in the cache and is available for read cache. 5 Click OK. Storage Manager Pro changes the properties immediately. Saving and Restoring a Configuration to a File Storage Manager Pro allows you to save a current configuration to a file for later use. This allows you to configure other controllers on other systems with the same size and type of drives. This is useful if you want to set up multiple systems with the same configuration or in the event you want to re-create a configuration after a crash. 3-5
