clone - UPS driver clone
This man page only documents the specific features of the clone driver. For information about the core driver, see nutupsdrv(8).
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.
This driver supports the following settings:
The port specification in the ups.conf(5) reference the driver socket that the "real" UPS driver is using. For example:
driver = usbhid-ups
port = auto
driver = clone
port = usbhid-ups-realups
load.on = outlet.1.load.on
load.off = outlet.1.load.off
load.status = outlet.1.status
Unlike a real UPS, you should not configure a upsmon master for this 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.
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.
