Hi all,
We have an interesting case here where some volumes' relationships are not listed in snapmirror list-destinations REST api.
However, these volumes' relationships are clearly visible and present in both ontap console and REST api CLI passthru as described below.
The problematic volume used in this case is SL10248 but there are more. Our ontap is NetApp Release 9.7P13: Thu Apr 15 02:06:46 UTC 2021
Check the SL10248 relationships using ontap CLI, observe two relationships present

Check the SL10248 relationships using REST API CLI passtgrough. Observe two relationships present, same as above:
simacr@simacr-linux:~$ curl --insecure --user user:pass "https://con-svm-201/api/private/cli/snapmirror/list-destinations?source-volume=SL10248&fields=relationship_id"

Check the snapmirror relationships using proper REST API call. List all relationships to avoid filtering ambiguities. Redirect to file due to size. Grep the output for SL10248 AND by UUID to confirm the missing relationships. Show the output sample to prove the output contains valid data, but incomplete regarding SL10248:
simacr@simacr-linux:~$ curl --insecure --user user:pass "https://con-svm-201/api/snapmirror/relationships/?list_destinations_only=true&fields=source" >o
