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 command 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 minutes 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 spindown, 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.
