I have configured volume_driver as emc_smis_driver but it is not loaded. Default lvm is loaded. Here is my setup details.

Controller node : Host A cinder-api and cinder-scheduler configured

Compute node : Host B cinder-volume configured

vinder.conf file on Host B

volume_driver = cinder.volume.drivers.emc.emc_smis_fc.EMCSMISFCDriver
cinder_emc_config_file = /etc/cinder/cinder_emc_config.xml

zoning_mode = fabric

[fc-zone-manager]
fc_fabric_names = openstack
zoning_policy = initiator-target
brcd_sb_connector = cinder.zonemanager.drivers.brocade.brcd_fc_zone_client_cli.BrcdFCZoneClientCLI
fc_san_lookup_service = cinder.zonemanager.drivers.brocade.brcd_fc_san_lookup_service.BrcdFCSanLookupService
zone_driver = cinder.zonemanager.drivers.brocade.brcd_fc_zone_driver.BrcdFCZoneDriver

I am tried creating volumes but it end up with these errors.

In /var/log/cinder/cinder-volume.log the loaded volume_driver is lvm but i configured to load emc driver. By default cinder is loading lvm as volume driver

volume_driver = cinder.volume.drivers.emc.emc_smis_fc.EMCSMISFCDriver
cinder_emc_config_file = /etc/cinder/cinder_emc_config.xml
