Changing Power Settings

The RAID controller includes Dimmer Switch™ 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.
Note: 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.
1. Select the Physical View tab in the left panel of the MegaRAID
Storage Manager window, and select a controller icon.
2. In the right panel of the MegaRAID Storage Manager window, select
the Operations tab, and select Power Settings.
Figure 8.29 displays the Operations menu and the Power Settings
field.
3. 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
- Powersave after their status.
If you go back to the Power Settings operation, the checkbox
displays the saved setting.
