Dear Toasters,
Can anyone please give me some tips on APC-UPS monitoring.
I have many APC Smart UPS'es and i use them to protect my File Servers. In the past when we used Sun hardware, we used to use the "Powerchute" software from APC. Now APC needs you to run some sort of Windows-box to be able to monitor all your machines.
I heard about apcupsd on another list and gave that a shot and it seems to do a pretty decent job when it comes to linux.
To protect my NetApp's, i am planning to use apcupsd on a linux machine and then try and somehow "correctly" use it to shutdown the netapp. I need to be careful about shutting down the netapp ONLY when the power is down and not every time the linux machine needs to be brought down.(so maybe an rc script WONT work)
Any ideas ? Comments ?
Thanks,

As far as I know, NetApps can survive a power cut without a problem. I heard that back in the old days, Tom Mendoza used to demonstrate the robustness of the filer by yanking the power during customer presentations.

Called NetApp and the looks like 6.3 and 6.4 have a "ups" command that you can use to connect to a UPS with a network interface(ONLY)
I have lost power a couple of times and havent really had a problem...but dont want to count on that. Looks like i will have to though..

There seems to be very little documentation regarding this, other than the syntax of the 'ups' command.
I'm interested in this as well, but mainly for consistency -- the filer usually handles power outages fairly well with its NVRAM (as long as the NVRAM batteries are good). We have everything in the same room on UPS, and it'd be nice to have the filer acknowledge UPS battery state as well...
However, it seems that my F760 running DOT 6.3.1R1 doesn't recognize my APC Silcon DP330E UPS (a room-sized MONSTER UPS, which we manage through a Web/SNMP interface).
Has anyone played around with the 'ups' command in DOT at all? Is this one of those things where you have to pay NetApp extortion to get a "license" to use your own toaster?
All I can coax out of my toaster is:
toaster> ups add -c xxx 10.1.1.10 ups: make/model could not be determined. You might be trying to add a make/model of ups that is not know to the filer. Please verify that the UPS is a supported model.
But, how do I determine which UPS's are supported? There doesn't seem to be ANYTHING in ANY file regarding UPS's, other than the SNMP MIBs...now.netapp.com isn't much help either...
BTW, null, we use a (home-grown) monitoring script, which I wrote, to poll the SNMP/Web interface of the UPS for battery status. When the "battery remaining" gets below a certain time value, the systems page the sysadmins, and shut themselves down in anticipation of total power loss. Then of course, somebody has to physically be in the room to restart all the systems when the UPS comes back online... This handles the situation where simply going to battery on UPS doesn't cause the systems to go offline -- they actually USE the UPS's battery.

I use the Smart UPS'es and so dont have a network connection. Cant use the NetApp functionality anyways, i was wondering if anyone actually had a solution to work around this problem...

I'm using "Network UPS Tools":
Not currently directly shutting down the filer (since we have two 100Kva UPSes, and plenty of time to do an orderly manual shutodwn), but just doing notification right now of outages.
