Actually I then found the "Host Utilities Installation and setup 6.0"
guide from NetApp with reference to multipath config for rh el 5.6 and
up. So my starting config will be this one:

         device {
                vendor                  "NETAPP"
                product                 "LUN"
                getuid_callout          "/sbin/scsi_id -g -u -s /block/%n"
                prio_callout            "/sbin/mpath_prio_alua /dev/%n"
                features                "1 queue_if_no_path"
                hardware_handler        "1 alua"
                path_grouping_policy    group_by_prio
                failback                immediate
                rr_weight               uniform
                rr_min_io               128
                path_checker            directio
        }
}

It could be interesting to propose a different default, perhaps?
