    Command:

    clone

    
    
    

    NOTE

           This man page only documents the specific features of the clone driver.
           For information about the core driver, see nutupsdrv(8).
    
    
    

    DESCRIPTION

           This driver, which sits on top of another driver socket, allows users
           to group clients to a particular outlet of a device and deal with this
           output as if it was a normal UPS.
    
    
    

    EXTRA ARGUMENTS

           This driver supports the following settings:
    
           load.off=command
               Recommended. Set the command on the "real" UPS driver that will be
               used to switch off the outlet. You need both load.off and load.on
               in order to power cycle the outlet. Otherwise, shutting down the
               clients powered by an outlet is a one way street (see IMPORTANT).
    
           load.on=command
               Recommended. Set the command on the "real" UPS driver that will be
               used to switch on the outlet. You need both load.off and load.on in
               order to power cycle the outlet. Otherwise, shutting down the
               clients powered by an outlet is a one way street (see IMPORTANT).
    
           load.status=value
               Recommended. Set the variable on the "real" UPS driver that will be
               used to indicate the outlet status (i.e. on/off). If not specified,
               the clone driver will attempt to keep track of the outlet status,
               but this is less reliable.
    
           offdelay=num
               Set the timer (in seconds) before the outlet is turned off after
               the shutdown condition (OB LB) for this outlet is met or a command
               to shutdown was issued. Defaults to 120 seconds.
    
           ondelay=num
               Set the timer (in seconds) for the outlet to switch on in case the
               power returns after the oulet has been switched off. Defaults to 30
               seconds.
    
           mincharge=value
               Set the remaining battery level when the clone UPS switches to LB
               (percent).
    
           minruntime=value
               Set the remaining battery runtime when the clone UPS switches to LB
               (seconds).
    
    
    

    IMPLEMENTATION

           The port specification in the ups.conf(5) reference the driver socket
           that the "real" UPS driver is using. For example:
    
           driver. When a upsmon master sees the OB LB flags and tells the upsd
           server it is OK to initiate the shutdown sequence, the server will
           latch the FSD status and it will not be possible to restart the systems
           connected without restarting the upsd server.
    
           This will be a problem if the power returns after the clone UPS
           initiated the shutdown sequence on it's outlet, but returns before the
           real UPS begins shutting down. The solution is in the clone driver,
           that will insert the FSD flag if needed without the help of a upsmon
           master.
    
    
    

    CAVEATS

           The clone UPS will follow the status on the real UPS driver. You can
           only make the clone UPS shutdown earlier than the real UPS driver, not
           later. If the real UPS driver initiates a shutdown, the clone UPS
           driver will immediately follow.
    
           Be aware that the commands to shutdown/restart an outlet on the real
           UPS drivers are not affected, so if you tell the real UPS driver to
           shutdown the outlet of the clone UPS driver, your clients will lose
           power without warning.
