I think I know the answer to this question based on all of the research I've done, but figured I'd ask anyway. I needed a couple of servers for an HA cluster, and our "order" guy here ordered me a couple of Dell PowerEdge T110 II. I'd planned on using IPMI to fence these things with, but later found out that this model is only one of two PE servers Dell sells that has a stripped down BMC on it, and allows only local access. It's my fault for not looking closer at the specs, but I figured a PowerEdge server would have the stuff I needed. So now I'm looking for a way to fence these without purchasing more equipment. I thought maybe IF-MIB, but I can't discover enough about that to determine whether that'll work for me. I find it strange that using Conga (luci) from a third administration server I can reboot these two Dell nodes, and wonder why that works, how it's done, and why that wouldn't work as a fence method. Any one dealt with this particular Dell PE and fencing in any form other than using something like an APC fence? Thanks for any suggests. I've pretty much wore Google out, and I'm now in that round-robin mode of results where everything leads back to the same pages on different servers. steve campbell

All 3 are a basic configuration (no iDrac express or enterprise). But they do have ipmi and are controllable and fencable via lan. These boxes just share ipmi with the onboard nic. Are you sure yours are only accessible locally? And if you have local ipmi I see no reason why external should not work.
