The new machines are intended to be use as a web servers running
PERL, PHP, Tomcat(maybe), Mysql
Again, all I want to do is have one running and the second one as a failover
and I want to be able to have identical software on each machine.
Thanks,
Néstor :-)

Depending on the applications you intend to run on these machines upgrading to RHEL 4 might be a better option still. AFAIK not all middleware and such is certified for RHEL 5 yet so you might want to check that first.
