MegaRAID Storage Manager Online Help System |
Changing Power Settings
The RAID controller includes Dimmer Switchâ„¢ technology that conserves energy by placing certain unused drives into powersave mode. You can use the Power Settings field to choose whether to allow unconfigured drives to enter powersave mode.
When this option is selected, unconfigured drives may be spun down. When not selected, these drives are not spun down. The controller will automatically spin up drives from powersave mode whenever necessary. The powersave option is not selected by default. You have to select it to enable spin-down of drives.
If your controller does not support this option, the Power Settings field does not display.
Follow these steps if you need to change the powersave setting.
- Select the Physical View tab in the left panel of the MegaRAID Storage Manager window, and select a controller icon.
- In the right panel of the MegaRAID Storage Manager window, select the Operations tab, and select Power Settings.
- Click Go to allow unconfigured drives to enter powersave mode.
Your power settings are saved and the screen is refreshed so that the Operations tab is selected, but no operations are selected. On the device menu in the left panel of the physical view screen, the nodes for the unconfigured good drives that are spun down appear with - Powersave after their status.
The unconfigured good drives go to spun-down mode after 30 minutes if they are not used for a configuration, or they can be manually spun down using the option Prepare for Removal.
If you go back to the Power Settings operation, the checkbox displays the saved setting.
