The Fibre Channel Zone Manager allows FC SAN Zone/Access control management in conjunction with Fibre Channel block storage. The configuration of Fibre Channel Zone Manager and various zone drivers are described in this section.

If Block Storage is configured to use a Fibre Channel volume driver that supports Zone Manager, update cinder.conf to add the following configuration options to enable Fibre Channel Zone Manager. Make the following changes in the /etc/cinder/cinder.conf file. To use different Fibre Channel Zone Drivers, use the parameters described in this section. When multi backend configuration is used, provide the zoning_mode configuration option as part of the volume driver configuration where volume_driver option is specified. Default value of zoning_mode is None and this needs to be changed to fabric to allow fabric zoning. zoning_policy can be configured as initiator-target or initiator

Brocade Fibre Channel Zone Driver performs zoning operations via SSH. Configure Brocade Zone Driver and lookup service by specifying the following parameters: Configure SAN fabric parameters in the form of fabric groups as described in the example below: Define a fabric group for each fabric using the fabric names used in fc_fabric_names configuration option as group name.

Brocade Fibre Channel Zone Driver requires firmware version FOS v6.4 or higher. As a best practice for zone management, use a user account with zoneadmin role. Users with admin role (including the default admin user account) are limited to a maximum of two concurrent SSH sessions. For information about how to manage Brocade Fibre Channel switches, see the Brocade Fabric OS user documentation.
