I could have sworn that we got one of these units working in the past, but we must have been using a different firmware version or something. Implementing a new one even harder.Īnyway, the short answer is that the AP7900 just doesn't work with either the apcmastersnmp or the apcmaster STONITH modules. So, getting in and fixing one tends to be pretty hard work. The problem is that STONITH plug-ins are fairly complicated to implement because of the way they're designed. Of course, with the exception of the “external” plug-in which I designed, and Scott Kleihege largely implemented. I know I shouldn't be surprised, because it seems like every time I try to use one of the Heartbeat STONITH plug-ins I find it just doesn't work.
