Upgrading to Havana "Failed to invoke ems"

Just upgraded our test environment to Havana and am getting the following error:

So we can't schedule any volume builds because the scheduler thinks the netapp doesn't have any capacity.

We are using stable/havana (HEAD = ad05556a2f3acf11e7ab633fa59bf23a6cad11da)

Our ONTAP version is: 8.2P2

Should mention our cinder.conf options

netapp_server_port = 443
netapp_storage_family = ontap_cluster
netapp_storage_protocol = iscsi
netapp_transport_type = https
volume_driver = cinder.volume.drivers.netapp.common.NetAppDriver

Hi Sam,

What occurs when you run "event status show" from the Clustered ONTAP console?

Thanks!

Hi Sam. It arises because of the vsadmin role problem. The issue has been fixed in the change https://review.openstack.org/#/c/60183/ The file to fix ems in particular will be cinder/volume/drivers/netapp/utils.py. Let me know if it works for you.

Thanks
