dikkiedirk Posted January 20, 2013 Share Posted January 20, 2013 I have my UPS set-up and configured like shown in the attachment. What timings should I set to allow the server to properly powerdown? The settings as shown don't work because the server was shutdown "dirty" last night because of a power outage and is now running a parity check. Link to comment
S80_UK Posted January 20, 2013 Share Posted January 20, 2013 Depends on your UPS, the condition of its batteries, the load connected at the time of the failure, and so on. However, I would set the battery level to maybe 50%. This setting specifies how much charge can remain in the batteries before a shut down is initiated. I would also set time out to maybe 60 seconds rather than 300 which should make it see the mains failure more quickly. Link to comment

The UPS is a IBM rebrand of the APC SmartUPS 1500, it was installed march 2012, it shows a rumtime of 70 minutes when I am running a parity check. My server has 15 disks. Does the setting for Battery Level override the Minutes setting? What exactly does the timeout setting do? BTW, this was the first time the batteries were exhausted. The show full capacity now.

I'm guessing you have the wrong cable type configured. That is, unless there is another PC/server on the LAN that actually has the UPS connected to it. For any UPS connected directly to the unRAID server you would be using "smart" or "usb", or "serial" as cable type. All of the settings work together. The FIRST that is reached triggers a shutdown. So, if you still have 90% of battery capacity, but have been on the UPS for 5 minutes, the server will be shut down since 300 seconds have been reached. Or, if you had a much smaller UPS (or a larger load on it) and after 1 minute you only had 10% of battery capacity remaining, your server would be shut down. Or if you had an estimated 10 "Minutes" runtime left, it would start a shut down of the server... Whichever comes first starts the process. If you are using another PC for the UPS and communicating via LAN for status as it looks like you are configured, the router or switch must be powered by the UPS, or all communication with the UPS is lost on a power outage and it will run till its batteries are exhausted. You also have "kill ups" set to No. With that setting, the UPS will not shut itself off, and it WILL exhaust its batteries. That is typically NOT the setting you need unless the UPS is powering other devices needed after the server shuts down. Joe L. Link to comment
dikkiedirk Posted January 20, 2013 Author Share Posted January 20, 2013 The UPS has a 9617 Network Management Card in it and is connected directly to my network. No serial or USB connection is used. Link to comment
Joe L. Posted January 20, 2013 Share Posted January 20, 2013 The UPS has a 9617 Network Management Card in it and is connected directly to my network. No serial or USB connection is used. That explains it... (most UPS are not that sophisticated) You have a very nice UPS. You should have the "Kill UPS" set to Yes unless it is powering other devices which must stay on after the unRAID server shuts down. Is your router and/or switch powered by the UPS? (it must be for the UPS to communicate with the server in a power outage.) Do you have the "Clean Powerdown" add-on installed? The stock powerdown command in unRAID will not stop the server if any disk is busy and unable to be un-mounted. Joe L. Link to comment

Nice UPS yes, and cheap, got it as an open box item at a local IT shop complete with the 9617 card built in and ready to go. It communicates nicely with apcupsd. But even nicer would be to get it properly setup configured so that my server powers down clean in a power outage. My syslog shows: Jan 20 05:43:01 Tower1 logger: | Installing new package /boot/packages/apcupsd-3.14.3-i486-1kjz.tgz Jan 20 05:43:02 Tower1 logger: | Installing new package /boot/packages/powerdown-1.02-noarch-unRAID.tgz I guess those are the right packages for apcupsd and powerdown or not?and Link to comment
dikkiedirk Posted January 21, 2013 Author Share Posted January 21, 2013 If I set kill UPS to yes will the UPS be switched off? When will that happen? After the server has been cleanly shut down? Link to comment
S80_UK Posted January 21, 2013 Share Posted January 21, 2013 The command is sent to the UPS before the server shuts down (of course) but the UPS then waits a preset time before it switches off. In some APC UPS units you can configure that delay, but generally it is long enough by default. Link to comment
Joe L. Posted January 22, 2013 Share Posted January 22, 2013 If I set kill UPS to yes will the UPS be switched off? When will that happen? After the server has been cleanly shut down? Yes, Yes, the UPS shuts down after a delay sufficient for the server to finish shutting off. When power returns, and if you have the BIOS on your server set to power itself back up, the server will automatically start back up. Link to comment

My concern is that the server is shut down clean, so there will be no parity check when the server starts. So the kill ups command should be sent short before the the server shuts down. The array should be offline then at least. Link to comment
S80_UK Posted January 22, 2013 Share Posted January 22, 2013 As Joe L describes it in his post above... Yes, Yes, the UPS shuts down after a delay sufficient for the server to finish shutting off. My point was just to explain the sequence of events. My server has gone through several shut downs in this way caused by mains power failures and due to the UPS behaviour it always restarts without needing a parity check. Link to comment
dikkiedirk Posted January 23, 2013 Author Share Posted January 23, 2013 Good to hear! The default shutdown delay for my UPS is 90 seconds but I can inrease it easily if necessary. Link to comment
Joe L. Posted January 23, 2013 Share Posted January 23, 2013 Good to hear! The default shutdown delay for my UPS is 90 seconds but I can inrease it easily if necessary. Usually it is not necessary as the command to shut down the UPS is one of the very last things done on the server before it turns its own power off. It has already stopped the array and all other processes at that point. (or at least that is how it is handled in the unMENU install... never looked at the plugin version, but since it is basically a "plg" version copied from my unRAID .conf file, it should be the same.)
