[Rdo-list] Problem of integrating EMC VNX as Cinder backend:

When I try to use EMC driver to integrate EMC VNX to be cinder backend, I got following error in /var/log/cinder/volume.log 2013-05-13 14:40:52 CRITICAL [cinder] No module named emc Traceback (most recent call last): File "/usr/bin/cinder-volume", line 57, in <module> server = service.Service.create(binary='cinder-volume') File "/usr/lib/python2.6/site-packages/cinder/service.py", line 435, in create service_name=service_name) File "/usr/lib/python2.6/site-packages/cinder/service.py", line 330, in __init__ *args, **kwargs) File "/usr/lib/python2.6/site-packages/cinder/volume/manager.py", line 129, in __init__ configuration=self.configuration) File "/usr/lib/python2.6/site-packages/cinder/openstack/common/importutils.py", line 40, in import_object return import_class(import_str)(*args, **kwargs) File "/usr/lib/python2.6/site-packages/cinder/openstack/common/importutils.py", line 30, in import_class __import__(mod_str) ImportError: No module named emc My cinder.conf : [DEFAULT] logdir = /var/log/cinder state_path = /var/lib/cinder lock_path = /var/lib/cinder/tmp volumes_dir = /etc/cinder/volumes iscsi_helper = tgtadm sql_connection = mysql://cinder:cinder@127.0.0.1/cinder rootwrap_config = /etc/cinder/rootwrap.conf # VG based backend #volume_name_template = volume-%s #volume_group = cinder-volumes verbose = True auth_strategy = keystone # RabbitMQ rpc_backend = cinder.openstack.common.rpc.impl_kombu rabbit_host = 10.68.125.11 #EMC backend driver iscsi_target_prefix = iqn.1992-04.com.emc iscsi_ip_address = 198.19.10.111 volume_driver = cinder.volume.emc.EMCISCSIDriver #volume_driver = cinder.volume.emc.EMCSMISISCSIDriver cinder_emc_config_file = /etc/cinder/cinder_emc_config.xml [keystone_authtoken] admin_tenant_name = service admin_user = cinder admin_password = password auth_host = 10.68.125.11 auth_port = 35357 auth_protocol = http signing_dirname = /tmp/keystone-signing-cinder The cinder version is: openstack-cinder-2013.1-2.el6.noarch Kimi Zhang +86 186 0800 8182
