netapp cdot ipspace multiple subnets

[Maurice Escher]

I see an error on creating manila shares with the following setup:

Manila on Pike with DHSS=true on cDot netapp ontap 9.1.

Neutron Network net1 has two subnets sub1 and sub2.
I have respecting share networks sharenet_sub1 and sharenet_sub2.

I create share1 in sharenet_sub1 and share2 in sharenet_sub2.
share2 errors with:

" Port "nodeX:port1" cannot be used because it is currently the home port or current port of a LIF. To view LIFs with a specified home port, use the "network interface show -home-node <nodename> -home-port {<netport>|<ifgrp>}" command. To view LIFs with a specified current port, use the "network interface show -curr-node <nodename> -curr-port {<netport>|<ifgrp>}" command. "

on manila/share/drivers/netapp/dataontap/client/client_cmode.py in _remove_port_from_broadcast_domain
in https://github.com/sapcc/manila/blob/stable/pike-m3/manila/share/drivers/netapp/dataontap/client/client_cmode.py#L670-L674

same like master https://github.com/openstack/manila/blob/master/manila/share/drivers/netapp/dataontap/client/client_cmode.py#L715-L719

One subnet maps to one broadcast domain - ok.
One subnet maps to one ipspace. Subnets of the same network cannot overlap, why not map one neutron network instead to one ipspace?
Or somehow enable to add the port to both ipspaces? Or create a new port for the new subnet?

I'm happy to hear any suggestions.

Thanks,
Maurice

    NetApp ONTAP: Fix use of multiple subnets with DHSS=True

    NetApp ONTAP Multi-SVM driver was raising an error while trying to
    create shares on multiple subnets that belong to the same neutron
    network, as it was trying to map multiple ipspaces to the same VLAN
    port.

    This fix allows the driver to use the same ipspace and VLAN port across
    all subnets belonging to the same neutron network.
