NetApp: Failed to get info for aggregate

[Oisin]

NetApp driver is attempting and failing to get the aggregate capacity for the scheduler;
https://github.com/openstack/cinder/blob/master/cinder/volume/drivers/netapp/dataontap/client/client_cmode.py#L1510

I suspect this occurs as the driver is attempting to access a cluster level API with a SVM scoped account.

Looks like this bug was introduced in the "NetApp: Add aggregate capacity info to scheduler" commit;
https://review.openstack.org/#/c/335103/

The change was added to address the "Report NetApp cDOT aggregate capacity info to scheduler" blueprint;
https://blueprints.launchpad.net/cinder/+spec/netapp-report-aggregate-utilization

The following error message and traceback is spamming the cinder volume log;

[req-10239228-7cfe-44ee-8578-370761de516a - - - - -] Failed to get info for aggregate aggr1_02.

"I suspect this occurs as the driver is attempting to access a cluster level API with a SVM scoped account."

Your suspicion is correct.

We're spamming the log; this sort of check can be done and logged once.

    NetApp: Track SVM and Cluster scoped credentials

    This fix avoids logging an exception when a user
    chooses to use an SVM scoped account. cDOT
    driver requires cluster scoped privileges to
    gather backend statistics, performance
    counters, etc. These APIs are not available for
    SVM scoped credentials.

@Jose,

Would it be possible to have this fix back ported to the Newton release?
