Newbie UPS help
I am a newbie and I just got a Sun Ultra 5, and want an UPS. I have been looking at the different models, but I do not know which brand has software that is compatable with Solaris 2.8 for automatic shutdown. I have looked at the power setup options in Solaris, but there doesn't seem to be any options for auto shutdown. If anyone can help get me started, it would be much appreciated. Thanks

clone
CLONE(8) NUT Manual CLONE(8)
NAME
clone - UPS driver 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:
[realups]
driver = usbhid-ups
port = auto
[clone-outlet-1]
driver = clone
port = usbhid-ups-realups
load.on = outlet.1.load.on
load.off = outlet.1.load.off
load.status = outlet.1.status
[...]
IMPORTANT
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.
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.
