I'd go with IPMI, it's simpler. I recall someone recommending external/ipmi over ipmilan.so, so that's what I use, but I can't remember why exactly. The APC PDUs do support outlet groups spanning several PDUs, using multicast I believe. There's even a note about it in README.rackpdu in the cluster-glue package: ==== In case your nodes are equipped with multiple power supplies, the PDU supports synchronous operation on multiple outlets on up to four Switched Rack PDUs. See the User's Guide for more information on how to setup outlet groups. ==== What I'm not clear about is how to tell the apcmaster stonith plugin which outlet group to control. The only parameters mentioned in its built-in help are ipaddr, login, and password. -Andrew _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker
