NetApp API failed. Reason - 18177:Relationship is in use by SnapMirror in local cluster

[Maurice Escher]

Hi,

with DHSS=true on Xena with the NetApp driver on deleting a replica I get the following error:
https://paste.opendev.org/show/b8oLtjnFFydlPtZlI2yW/

The reason is: the snapmirror show command only show snapmirrors where the current cluster is the destination.

To also see snapmirrors where the current cluster is the source, you have to use snapmirror list-destinations.

So when there is still a replication setup the other way around to the one I'm trying to delete, I get above error, because the vserver peering is still in use.

The fix seems rather straightforward to me:
https://opendev.org/openstack/manila/src/commit/605925e8f4a70bb70a9921d6879101d30b7ad8b9/manila/share/drivers/netapp/dataontap/cluster_mode/lib_multi_svm.py#L703-L704
should use the client method 'get_snapmirror_destinations' instead of 'get_snapmirrors'

BR,
Maurice
