Oracle clustering system will be installed by Oracle experts (good for me ^_^)
and I assume it will be the RAC system which will manage the concurrent
accesses.
The point I can't understand is why I can't mount the shared partitions on both
servers :(
DELL support team answered me I need to use GFS instead of ext3, even if I
should be able to mount the partitions.
I'm a bit lost in this configuration, and even more since the Redhat clustering
suite has begun a special product sold apart :(

What file system is on the shared disk? What Cluster Management software are
you using?
Per oracle, you will use Oracle's Cluster Manager (oracm) and OCFS (oracle
clustering file system) to achieve this -- at least with 9i R2.
The Cluster Manager needs to be installed first (and running), you need to have
the shared disk mounted and you need to have the interconnect set up on the
machine. Once that is done, you need to install the Oracle Software.
This can be a little trick in itself (at least on 64 bit RHEL) to get the order
right and for the pieces to actually see all of the needed pieces at install
time (though it is supposedly possible to convert to rac after you already have
a DB also)
The Cluster Manager is on the DB Install CDs (it is an install option).
OCFS is downloadable from oss.oracle.com (don't use OCFS2 as it is only for a 2
.6 kernel)
