Spindown 0.2.2 (Default branch)
Spindown is a daemon to spin down idle disks andthus save energy and give the disks a longerlifetime. It also works with USB disks andhot-swappable disks because it uses the device IDto identify the disk instead of the device name(such as hda or sdb). This means that it doesn'tmatter if the disk is swapped while the daemon isrunning.License: GNU General Public License v3Changes:
The command configuration options now expect thewhole command to execute and not just only theparameters. It still defaults to "sg_start--stop". Gentoo init scripts were added. The FIFOis removed when shutting down the program.Image

NAME

       sys_attrs_pwrmgr - pwrmgr subsystem attributes

DESCRIPTION

       This reference page lists and describes attributes for the Power Manager (pwrmgr) kernel subsystem. To change these attributes so that they
       take effect each time you boot the system, you create a stanza file with the attribute settings you want and then use the sysconfigdb  com-
       mand  to  update  the  system configuration database with the information in this file. See the EXAMPLES section for more information about
       this process.  Refer to the sys_attrs(5) reference page for an general introduction to the topic of kernel subsystem attributes.

	      A value that enables (1) or disables (0) CPU slowdown after the CPU becomes idle.

	      A value that enables (1) or disables (0) all power management functions (for CPU, disks, and graphics hardware).	The number of min-
	      utes to wait before powering down registered disks after they become idle.

	      A value that enables (1) or disables (0) disk spindown after registered disks become idle.

	      The  number  of  minutes	before entering DPMS off mode after display hardware has become idle. If you specify 0 for this attribute,
	      DPMS off mode is disabled.

	      A value that enables (1) or disables (0) Display Power Management Signaling (DPMS) modes for graphics display hardware.

	      The number of minutes before entering DPMS standby mode after display hardware has become idle. If you specify 0 for this attribute,
	      DPMS standby mode is disabled.

	      The number of minutes before entering DPMS suspend mode after display hardware has become idle. If you specify 0 for this attribute,
	      DPMS suspend mode is disabled.

EXAMPLES

       The following example shows a sample stanza file named power_mgr.stanza:

       pwrmgr:
			 default_pwrmgr_state=1
			 cpu_slowdown=1
			 disk_spindown=1
			 disk_dwell_time=20
			 graphics_powerdown=1
			 graphics_standby_dwell=5
			 graphics_suspend_dwell=10
			 graphics_off_dwell=15

       This file: Enables power management in general, plus  all three of the power management options for idle hardware (CPU slowdown, disk spin-
       down, and DPMS modes for graphics displays) Specifies a wait of 20 minutes before spinning down a disk after it has become idle Specifies a
       wait of 5, 10, and 15 minutes before entering DPMS standby, suspend, and off modes,  respectively,  after  graphics  display  hardware  has
       become idle

       See stanza(4) for more information about stanza files.

       The  following command updates the /etc/sysconfigtab database with the information in the stanza file: # sysconfigdb -a -f power_mgr.stanza
       pwrmgr

       See sysconfigdb(8) for more information about using this command to update the system configuration database.
