(dual ethernet controllers and 1 separate controller for the heartbeat). Both are running linux-ha and are both connected to a dell powervault 220S storage array which is configured so that both hosts can access the drives concurrently (cluster mode). Im following the instructions at http://www.gyrate.org/archives/9 and am at step 17.. which says to configure CCS. I guess we could get an APC power switch, but what would you folks suggest? i.e. what model for just a 2 cluster node (each server has 2 power supplies). Or is there a better way? regards, Jason -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
