If a node is to be out of service for a longer period, it's best to remove it from the cluster for the time being. > last case I had boh ILOs on dieffrent Networksegments and was working on the > switch. > In both cases i got failover porblems. If I got it right, this also belongs to good/bad maintenance practice. When you say "the switch" do you mean the network switching device?

Though I still think that you could live with your ILOs. If the problem is network connectivity, try to improve that.
