Can it be that the clustered VGs on other LUNs that are skipped is the cause?

BTW: tomorrow I should have a SAN guy able to mask them ...

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

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:
