Hi John, on the "Parameters" line the different nodes should not be separated by ":". Each node should be specified by a separate "mgsnode=..." or "failover.node=..." statement. I'm not sure if separating the two interfaces of each node by "," is correct here, or if this should be splitted again in two separate statements.
