Topic: UPS - Nut How to (urgent)

[Laurent DINCLAUX]

Hi,

I have an UPS from centralion (http://www.centralion.com/product/blazer1000.html)

The bundled software is UPSmart. Got the rpm but X-window is necessary. So I have tried powstatd that have already done great jobs for me Unfortunatly, it doens't seems to work with my UPS, using powstatd -t, I don't notice any changes on signals when I run off power. I don't know how it is possible but it is.

I am now thinking of using NUT. Activated it from console and reboot. Pluged out power and nothing happens: seems the default NUT driver doens't match my UPS. As NUT's web site (http://www.exploits.org/nut/)  has really poor documentation, here where I am now:

- does anyone knows witch NUT driver will work with UPSmart cables ?
-  I want to test generic driver, how can I test NUT receives anything and/or recognizes my UPS ? Any monitoring tools for NUT that will do that job ?
- Seems NUT has a cgi web interface to monitor UPS actvity. Where are those cgi files ?

Thanks in advance

Hi,
I am using a APC ups with nut, are you using serial or usb? If serial have you tried USB, I believe that NUT is configured for USB by default, I just plugged my UPS in the USB port, started NUT, rebooted and tested the UPS, it shutdown my server gracefully - no problem. I have never tried to get the activity interface to work, I personally don't see a need for it, the power goes off, battery takes over, 40 minutes later the server shutdown gracefully. What more could you ask from a UPS? Although it would be nice to be able to send the signal to another server plugged into the UPS but I'm not that good! I did try to install the NUT rpm on SME 5.5 but I couldn't get it to work so I upgraded to 5.6u4. A search for NUT UPS found:

plus lots more. I hope this helps.
Regards,
Del

Well I went a little futher.

My ups uses serial port1. I found that page http://hutton.sh/~phil/blazer.html. It has a patch for my UPS but it also says that bestups driver should work. So here what I did:
# /sbin/e-smith/db configuration setprop nut Model bestups
# /sbin/e-smith/db configuration setprop nut Device /dev/ttyS0
# /sbin/e-smith/signal-event post-upgrade
# reboot

Now my ups.conf looks like that:
[UPS]
        driver = bestups
        port = /dev/ttyS0

I am know trying it. On power fail, nothing happens for now. I am waiting my ups goes to low battery.....

What should I do il I want to applie the patch provided on http://hutton.sh/~phil/blazer.html ?
Can I use rpm --rebuild ??

Little more further:

I did  a # service ups stop

Then # service ups start:
Starting bestups: Network UPS Tools - Best UPS driver 0.51 (1.2.0)
This program is currently running as nutups (UID 420)
/dev/ttyS0 is owned by user root (UID 0), mode 0660
Change the port name, or fix the permissions or ownership of /dev/ttyS0 and try again.
Unable to open /dev/ttyS0: Permission denied
                                                           [ FAILED ]
Starting upsd:                                             [   OK   ]
Starting UPS monitor (master):                             [   OK   ]

I did a quick workaround chmoding /dev/ttS0 to 777 (maybe there is a better way ??)

Then
# service ups start
Starting bestups: Network UPS Tools - Best UPS driver 0.51 (1.2.0)
Syncing with UPS: ..............................
Failed - giving up...
                                                           [ FAILED ]
Starting upsd:                                             [   OK   ]
Starting UPS monitor (master):                             [   OK   ]

Seems the driver is not working whith my UPS. How can iI apply the patch provided here: http://hutton.sh/~phil/blazer.html.
Please help !

Did you read the top of that website? just you asked how to patch it you just type what it says...

patch -p1 < ../nut-1.2.1-blazer.patch

Might sound silly but you could have missed it

Have you ever tried to appliy such patch on an rpm ???

Have to apply it to source and then recompile

Powstatd does not work because UPS which works with UPSmart have the another protocol. I have the same problem. I have bought the ScanPower UPS with UPSmart software. I contacted with the manufacture and they said that 1) I have to find the software which works with this protocol; 2) I have to find the libraries needed for UPSmart. They said that these libraries I can find in the RedHat 7.1 - 7.3 installation CD's. If you have any idea - contact me too
