If you take a look at the 5.3.0.9/6.0.0.4 readme file in the ODM module, you'll find the following(which was very hard to locate):

OPT 433503 = Removed HA concurrent support package for Symmetrix and CLARiiON considering

             those versions of HACMP are no longer supported. Manual deinstallation of the

             fileset is required if it's no longer needed.

The HA fileset was needed for HACMP 5.1 and below.  It's not needed now.

For XtremIO, I believe you should be using one of the recent ODM versions which has XtremIO support.
(Again, you will probably have to check the readme files in the ODM one by one for any differences)

Thanks Owen & Ray.  This is interesting, because back during the days of HACMP 5.4.1 (a major mid cycle release), I still had to use the HA concurrent support filesets.  If HA concurrent support filesets are no longer needed, why would EMC still package /usr/sbin/cluster/diag/clconraid.dat in ODM 5.3.1.0?  The two utilities I mentioned that comes from the HA concurrent support filesets are used to set up this clconraid.dat file.  Oh well, I went ahead and manually configured the clconraid.dat file and see if that works.

very thanks.
