Power Management of Disk Drives

You can override the power management of disk drives just as you can for monitors. When you change the idle time for disk drives, the idle time for all other devices and the system remains unchanged; only the setting for the disks' power changes. All disk drives connected to the system receive the same idle time.

For information on setting a different idle time for each disk drive, refer to the power.conf(4) man page.

To Change Disk Drive Power Management

1. Start Dtpower.

   This launches the Dtpower basic window.

2. In the Dtpower basic window, select More.

   The Quick Edit tab is displayed.

3. Check the Disks button.

   The corresponding pull-down list for idle time becomes active.

4. Either choose a time from the pull-down list of idle times or enter a unique value.

   Leave a blank space between the number you enter and units. Abbreviate the units to Sec, Min, or Hr, as appropriate. Decimal values are accepted. For example, if you enter 1.5 Hr, the disk drive idle time is set to 90 minutes.

   If you enter a new value, it is added to the list, and will be available the next time you use the pull-down list. The value will be displayed the way you entered it in the edit box.

5. Click OK.
