<br>works. Even when monitoring the status of the UPS works, you must still<br>make sure the system shuts down cleanly and reboots when power returns.<br>There is no better way to guarantee that, than to yank the mains cable
<br>from the UPS and see what happens (at a convenient time, that is).</blockquote><div><br>Yes, I know, but I'm scared to screw my raid during unclean shutdowns.<br></div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

<br>> Yes, I guess you're right, but I start to get sick of it.<br><br>You have every reason to. You expected something to work (and if your<br>UPS indeed would have used the SafeNet software, it would, or else give<br>
you an error message that the configuration was not OK) and instead it<br>is giving you all sorts of trouble. Please complain to the company that<br>sold you the UPS (or better yet, to Sweex for providing incorrect<br>information on their website).
