Ben, I did as you said, turning off apache on both nodes 1 and 2. When I put node 1 on standby, HA turned on httpd on node 2. When I brought it out of standby, HA turned on httpd on node 1, and turned it off on node 2. So, success! Thank you very much! OK, I think the lightbulb just got switched on. The Web sites on nodes 1 and 2 should be exactly alike. If node 1 goes down, then node 2 kicks in, delivering the exact same content. Right? Doh! (I'm going to ask for my college tuition money back :-) ). If I might press on, how would that work with a database (take any; we use sybase running on Linux here). If the database on the "back up" server/node 2 is off, to be powered on if the database on the node 1 is unavailable, how is data replicated between the two? I hope it's OK to ask this.
