It seems it was a problem/matter related with multipath layer, and I could
create the SD without masking the clustered LUNs
In fact, as I blacklisted the disks (PVs) that composed the VGs of the
interfering clustered logical volumes I was able to add the storage domain

Added this in my node multipath.conf
blacklist {
        wwid 3600507630efe0b0c0000000000001183
        wwid 3600507630efe0b0c0000000000001082
        wwid 3600507630efe0b0c0000000000001182
        wwid 3600507630efe0b0c0000000000001081
        wwid 3600507630efe0b0c0000000000001181
        wwid 3600507630efe0b0c0000000000001080
        wwid 3600507630efe0b0c0000000000001180
}

In case you think it should have succeeded also without multipath
blacklisting, you can compare previous vdsm.log with errors I already sent
with the one generated right now with successful creation here:
