Xymon has a problem with clusters. It should be possible to tell Xymon
that "these nodes are in a cluster, so don't alert me unless at
least N of them are down at the same time". Right now, it isn't.

So if you want to eliminate the red status on the individual nodes
in the cluster, you cannot do that.

If it's only the alerts you want to stop, then you can configure 
no alerts to be sent for the individual nodes - only send alerts
for the cluster status (bskidmsrv001.ldap or .ldaps).
