Hey rcallawa, sorry for the delay in replying - I'm not sure why I didn't get an email when you replied...
Anyway, in reply to your questions, this cloud started life on Folsom and has been upgraded through Grizzly -> Havana -> Icehouse on RHEL6.
netapp_volume_list is unset in cinder.conf. 😞
I suggest that if netapp_volume_list is unset, then NO volume should be used, that 'cinder create' should fail until it is set.
In Folsom/Grizzly era the netapp driver would create (at least) one volume per tenant. I assumed this was to enforce tenant quotas. How are tenant quotas enforced now that we're supposed to specify the FlexVol all the iscsi LUNs are supposed to get created in?
Ugh - 549 LUNs to move out of the /var/lib/glance NFS volume.
