Is it possible that the setting is being affected by nova.conf and has gone the direction of iSCSI multipath?

[libvirt]
volume_use_multipath = False (Boolean) Use multipath connection of the iSCSI or FC volume

it seems that you are using iSCSI? if yes, enable multipath or not is controlled by connector, in other word, it is controlled by Nova. https://github.com/openstack/cinder/blob/master/cinder/volume/drivers/ibm/storwize_svc/storwize_svc_iscsi.py#L161
