Yes. Just "route add -host target target" entries, and in.mpathd will use those as ping targets. > Its a real stablity problem when an arbitrary server is rebooted and a > couple of > interfaces on a couple of logical domains goes into failed mode, when mpathd > decides errouneously that the network has failed. > > So I am going to try to set up routes to imaginary subnets to > populate the localrouting table with stable polladresses. > > > What could go wrong if I do this ? > Why isnt there an other method for telling Mpathd what polladdresses to > use ? I suppose you could file an RFE. I think the reason it's done that way is to make sure that all of the routing-related configuration information is located in one place. And, by default, the routes in the kernel's forwarding table point to local routers, which are normally _good_ things to be probing. If this is OpenSolaris (I hope it is), then you can use "ipmpstat -t" to learn more about the targets. I'd thought there was a general way to disable this entirely, but I can't find it at the moment ... -- James Carlson 42.703N 71.076W <carls...@workingcode.com> _______________________________________________ networking-discuss mailing list networking-discuss@opensolaris.org
