multipath on ps5500 with a bit modern Linux - how?

hi everybody,

I'm trying to get multipath do its job but I'm afraid I've got lost as where I make an error/mistake.

There is a few howtos on Dell website but those regards old OS version, one could say ancient, would be great to see those updated, or write anew for oses like rhel 7.x

My problem. I have what I think is simple multipath yet system does not get the Equallogic multipathed.

Could and Eqlx expert cast an eye on the config:

defaults {
  polling_interval       10
  path_selector              "round-robin 0"
  path_grouping_policy   multibus
  prio                           alua
  path_checker              tur
  rr_min_io                    100
  max_fds                      8192
  rr_weight                    priorities
  failback                    immediate
  no_path_retry              fail
  user_friendly_names     yes
}

blacklist {
  devnode ".*"
  wwid    "*"
}
blacklist_exceptions {
    #devnode                 "(sdq|sds|sdr)"
    wwid                    "36090a028004bb5e2faa1e4f9edafc883"
    wwid                    "36090a028004b353affa114faedaf48ca"
    wwid                    "36090a028004bd5c3efa604fbedafc880"
}

multipaths {
  multipath {
    wwid                    36090a028004bb5e2faa1e4f9edafc883
    alias                   equalLogic-0
    path_selector           "round-robin 0"
    path_grouping_policy    group_by_prio
    rr_min_io               10
    rr_weight               priorities
    failback                immediate
    features                "1 queue_if_no_path"
  }
  multipath {
    wwid                    36090a028004b353affa114faedaf48ca
    alias                   equalLogic-1
    path_selector           "round-robin 0"
    path_grouping_policy    group_by_prio
    rr_min_io               10
    rr_weight               priorities
    failback                immediate
    features                "1 queue_if_no_path"
  }
  multipath {
    wwid                    36090a028004bd5c3efa604fbedafc880
    alias                   equalLogic-2
    path_selector           "round-robin 0"
    path_grouping_policy    group_by_prio
    rr_min_io               10
    rr_weight               priorities
    failback                immediate
    features                "1 queue_if_no_path"
  }
}

and suggest what might be wrong there? I don't port-channel client's connection, and the connection is configured like this:

team.config:                            {"runner": {"name": "activebackup", "active": true, "fast_rate": true, "tx_hash": ["eth", "ipv4", "ipv6"]}, "link_watch": {"name": "ethtool"}}

Which I believe should result in iface being what a while ago was called a bond device.

Every help would be great to receive.
