ATACTL(8)               NetBSD System Manager's Manual               ATACTL(8)


NAME

     atactl - a program to manipulate ATA (IDE) devices


SYNOPSIS

     atactl device command [arg [...]]


DESCRIPTION

     atactl allows a user or system administrator to issue commands to and
     otherwise control devices which reside on standard IDE and ATA con-
     trollers.  It is used by specifying a device to manipulate, the command
     to perform, and any arguments the command may require.


DEVICE COMMANDS

     The following commands may be used on IDE and ATA devices.  Note that not
     all devices support all commands.

     identify

     Identify the specified device, displaying the device's vendor, product,
     revision strings, and the device's capabilities.

     idle

     Place the specified device into Idle mode.  This mode may consume less
     power than Active mode.

     standby

     Place the specified device into Standby mode.  This mode will consume
     less power than Idle mode.

     sleep

     Place the specified device into Sleep mode.  This mode will consume less
     power than Standby mode, but requires a device reset to resume operation.
     Typically the wd(4) driver performs this reset automatically, but this
     should still be used with caution.

     setidle idle-timer

     Places the specified device into Idle mode, and sets the Idle timer to
     idle-timer seconds.  A value of 0 will disable the Idle timer.

     setstandby standby-timer

     Places the specified device into Standby mode, and sets the Standby timer
     to standby-timer seconds.  A value of 0 will disable the Standby timer.

     checkpower

     Will print out if the device is in Active, Idle, or Standby power manage-
     ment mode.

AUTHORS

     The atactl command was written by Ken Hornstein.  It was based heavily on
     the scsictl(8) command written by Jason R. Thorpe.


BUGS

     The output from the identify command is rather ugly.
