       sys_attrs_pwrmgr - pwrmgr subsystem attributes

DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

       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.
