Openstack Ocatal manila failed to connect Netapp FAS8040

[MarginHu2017]

Hi  Experts,

I'm using Openstack upstream Ocata version, and netapp FAS8040 as Manila backend.

manila.conf

[netapp]
share_backend_name = netapp
share_driver = manila.share.drivers.netapp.common.NetAppDriver
driver_handles_share_servers = False
netapp_storage_family = ontap_cluster
netapp_server_hostname = 192.168.140.51
netapp_server_port = 80
netapp_login = admin
netapp_password = XXXXX
netapp_vserver = svm_nfs
netapp_transport_type = http
netapp_aggregate_name_search_pattern = ^((?!aggr1_sas).)*$

I'm sure  all parameters are right, but don't know why driver failed to initialize?

Two suggestions for you to consider:

• Check to make sure you have enabled http communication on the cluster. It’s disabled by default and needs priv advanced to set.
• Check the regex... ^((?!aggr1_sas).)*$ should be ^((?!aggr1_sas).*)$

Hi，

I‘m sure my netapp fas8040 is using http protocol not https, because my openstack cinder use http to connnect the equipment successfully.

Still failed after modify the paramter :

 netapp_aggregate_name_search_pattern = FAS8040_01_aggr1_sas

Finally , I solved this issue by the following command: ntap01::> vserver modify -vserver svm_nfs -aggr-list
