cinder iscsi driver initialization failed

MarginHu2017 — Wed, 04 Jun 2025 15:01:22 GMT

Hi Guys,

I'm using Openstack community upstream Ocata with Netapp Storage FAS8040, and found cinder iscsi driver initialization failed, the following is configuration and log,

you can check detail info from the attachement.

cinder.conf

[NetappIscsiBackend]
volume_backend_name = NetappIscsiBackend
volume_driver = cinder.volume.drivers.netapp.common.NetAppDriver
netapp_server_hostname = cloud-sz-netapp-b14-02.sz.cloud.genomics.cn
netapp_transport_type = https
netapp_server_port = 443
netapp_storage_protocol = iscsi
netapp_storage_family = ontap_cluster
netapp_login = admin
netapp_password = netapp123
netapp_vserver = svm_iscsi
#netapp_vserver = ntap01
max_oversubscription_ratio = 1.0
reserved_percentage = 5
use_multipath_for_image_xfer = True

Have you tried the steps from the following document?

http://netapp.io/2017/02/15/use-certificate-verification-netapp-ontap-openstack-cinder-driver/

Re: cinder iscsi driver initialization failed

MarginHu2017 — Tue, 06 Jun 2017 18:25:14 GMT

yes, I have tried but the issue still appeared, maybe I do something wrong because my os is centos7 not Ubuntu.

Last , I enable http protocol on the netapp storage , and use http instead of https , this is only workaround.

I hope netapp offer a detail solution for it.

Hi Netapper :

any progress ?
