DESCRIPTION
This reference page lists and describes attributes for the Power Man‐
ager (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 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 dis‐
play 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 Manage‐
ment 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 min‐
utes 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.
