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, only the power management settings for the disks changes. All disk drives connected to the system receive the same idle time. The idle time for all other devices and the system remains as specified in the Default System Idle Time box, see Figure 23–3.

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 Disk Drives - Sleep After Idling For 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 in the edit box.

   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, the value is added to the list, and is available the next time you use the pull-down list. The value is displayed in the format you use in the edit box.

5. Click OK.
