<P class=MsoNormal><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I am
running cluster suite with RH ES 3.0 and 7 server nodes, and have a
configuration question.<SPAN style="mso-spacerun: yes"> </SPAN>I would
like to have a backup server in my configuration which is normally not running
any services – failed services in my cluster are to always failover to the
backup server.<SPAN style="mso-spacerun: yes"> </SPAN>I think I can do
this by having restricted failover domains consisting of 2 members – the active
server and the backup; i.e. there would be 6 <SPAN
class=862290014-20092004>such </SPAN>restricted failover domains defined, one
for each active server (or maybe there is an easier way – any suggestions?)<SPAN
class=862290014-20092004>, all pointing to the same backup
server.</SPAN></SPAN></P>

<P class=MsoNormal><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"><SPAN
class=862290014-20092004>The</SPAN> problem is that <SPAN
class=862290014-20092004>my cluster configuration currently obtain the IP
address of the backup server through DNS. After a failure occurs we are
changing the DNS so that a different server assumes the backup role - in other
words, after the services are switched to the backup and the failed server is
repaired, the repaired server then assumes the backup server
role. Since the IP addresses of the servers in the cluster suite are
obtained through DNS, this effectively changes the IP addresses out from under
the cluster suite, and I'm not sure what effect this may have on the
system. Is there a better way to achieve what we are trying to
do?</SPAN></SPAN></P>
