Share instance xxx failed on creation.

[TatusGepetto]

Hi,

I'm facing an issue with share creation when DHSS is True and huawei is used as a backend. My error code is:

I configured huawei_backend as below, but I'm not sure if NFSClient IP is the one which should be taken or it has to be something else:

<?xml version='1.0' encoding='UTF-8'?>
<config>
    <Storage>
            <Product>Dorado</Product>
            <LogicalPortIP>10.1.20.100;10.1.20.101;10.1.20.102;10.1.20.103</LogicalPortIP>
            <RestURL>https://10.1.0.247:8088/deviceManager/rest/</RestURL>
            <UserName>xxx</UserName>
            <UserPassword>!xxx</UserPassword>
    </Storage>
    <Filesystem>
            <StoragePool>StoragePool001</StoragePool>
            <NFSClient>
                    <IP>100.71.0.253</IP>
            </NFSClient>
    </Filesystem>
</config>

100.71.0.253 -> this IP is taken directly from neutron network which is defined as attached:

If I'm doing something wrong - please let me know. Or if something else has to be defined - let me know. Thanks in advance.
