REST API: Error when PATCHing volume comment

pbolin

We are testing some functionality in the new REST API, and I have been having issues with updating volume comments on a couple filers. Filers I have tested on are running:
NetApp Release 9.7P11D1: Wed Jan 27 17:40:19 UTC 2021
NetApp Release 9.7P8: Thu Oct 15 04:11:57 UTC 2020
NetApp Release 9.8P4: Mon May 03 09:22:00 UTC 2021

I suspect there is some issue with the job control in some way, but I have not been able to verify. Have poked around in logs in systemshell as well as checked 'job history show' for any clues. I submitted a case to Support and they suggested I ask here.

 

The program I am using to do the updates:
import netapp_ontap
from netapp_ontap import config, HostConnection, NetAppRestError, utils
from netapp_ontap.resources import Svm, Volume, Aggregate, VolumeMetrics, Cluster, Node, CLI
from pprint import pprint as pp
import logging
logger = logging.getLogger()
logger.setLevel(logging.DEBUG)
ch = logging.StreamHandler()
ch.setLevel(logging.DEBUG)
logger.addHandler(ch)

utils.DEBUG = 1
utils.LOG_ALL_API_CALLS = 1

naauth = {'username': <USER> , 'password': <PASS>}

admin = <FILER>
with HostConnection(admin, verify=False, **naauth):
netapp_ontap.host_connection._HOST_CONTEXT.port=<PORT>
resource = Volume(uuid='dbdccb94-c936-11eb-b0cb-00a098ce3ae6')
resource.comment = "testingacomment"
result = resource.patch()
if result.is_err:
logger.error(f"Volume Comment Update Failed - {result.http_response.status_code} - {result.http_response.reason}")

Actually a better place to ask REST API questions is on Slack in the Netapp API channel.  Go to netapp.io and click on the Slack icon at top-right.  Post your question in the #api channel and you should get a response fairly quick.

The issue is that a volume has 2 UUIDs: uuid and instance_uuid.   The uuid was initially accepted, but the job reported a failure as described above.  When switching to the instance_uuid, the call succeeded.
