Seems to be a regression caused by https://bugs.launchpad.net/cinder/+bug/1328681

defining 2 fabrics works as expected fc_fabric_names=BRCD_FAB_1, BRCD_FAB_2

How to reproduce
1. configure FCZM
2. create FC volume
3. Attach FC volume
3. Detach FC volume

[fc-zone-manager]
brcd_sb_connector=cinder.zonemanager.drivers.brocade.brcd_fc_zone_client_cli.BrcdFCZoneClientCLI
#fc_fabric_names=BRCD_FAB_1

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
zoning_policy=initiator-target

[BRCD_FAB_1]
fc_fabric_address=
fc_fabric_user=

zone_activate=true

[BRCD_FAB_2]
fc_fabric_address=
fc_fabric_user=
fc_fabric_password=
zoning_policy=initiator-target

Seems to work as expected with

fc_fabric_names=BRCD_FAB_1, BRCD_FAB_2

Can you paste the exact definition in cinder.conf that is NOT working? From the snippet in the bug description, it looks as though BRCD_FAB_1 doesn't have values for any parameters.

Ok, that's fine, I understand. But why is fc_fabric_names commented out?
#fc_fabric_names=BRCD_FAB_1

This issue is not reproducible in my environment. I'm successfully able to attach/detach with zoning when a single fabric is listed in the conf file. Also, the original error in the bug shows invalid firmware error. Are you using the correct firmware? With the changes made for performance bug, the firmware check is removed, so you shouldn't hit this error anymore.
