Fibre Channel Zone Manager¶

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.

Configure Block Storage to use Fibre Channel Zone Manager¶

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.

Description of zoning configuration options
Configuration option = Default value	Description
[DEFAULT]
`zoning_mode` = `None`	(String) FC Zoning mode configured
[fc-zone-manager]
`fc_fabric_names` = `None`	(String) Comma separated list of Fibre Channel fabric names. This list of names is used to retrieve other SAN credentials for connecting to each SAN fabric
`fc_san_lookup_service` = `cinder.zonemanager.drivers.brocade.brcd_fc_san_lookup_service.BrcdFCSanLookupService`	(String) FC SAN Lookup Service
`zone_driver` = `cinder.zonemanager.drivers.brocade.brcd_fc_zone_driver.BrcdFCZoneDriver`	(String) FC Zone Driver responsible for zone management
`zoning_policy` = `initiator-target`	(String) Zoning policy configured by user; valid values include “initiator-target” or “initiator”

To use different Fibre Channel Zone Drivers, use the parameters described in this section.

Note

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.

Note

Default value of zoning_mode is None and this needs to be changed to fabric to allow fabric zoning.

Note

zoning_policy can be configured as initiator-target or initiator

Brocade Fibre Channel Zone Driver¶

Brocade Fibre Channel Zone Driver performs zoning operations through HTTP, HTTPS, or SSH.

Set the following options in the cinder.conf configuration file.

Description of brocade zoning manager configuration options
Configuration option = Default value	Description
[DEFAULT]
`zoning_mode` = `None`	(String) FC Zoning mode configured
[fc-zone-manager]
`brcd_sb_connector` = `HTTP`	(String) South bound connector for zoning operation

Configure SAN fabric parameters in the form of fabric groups as described in the example below:

Description of brocade zoning fabrics configuration options
Configuration option = Default value	Description
[BRCD_FABRIC_EXAMPLE]
`fc_fabric_address` =	(String) Management IP of fabric.
`fc_fabric_password` =	(String) Password for user.
`fc_fabric_port` = `22`	(Port number) Connecting port
`fc_fabric_ssh_cert_path` =	(String) Local SSH certificate Path.
`fc_fabric_user` =	(String) Fabric user ID.
`fc_southbound_protocol` = `HTTP`	(String) South bound connector for the fabric.
`fc_virtual_fabric_id` = `None`	(String) Virtual Fabric ID.
`principal_switch_wwn` = `None`	(String) DEPRECATED: Principal switch WWN of the fabric. This option is not used anymore.
`zone_activate` = `True`	(Boolean) Overridden zoning activation state.
`zone_name_prefix` = `openstack`	(String) Overridden zone name prefix.
`zoning_policy` = `initiator-target`	(String) Overridden zoning policy.

Note

Define a fabric group for each fabric using the fabric names used in fc_fabric_names configuration option as group name.

Note

To define a fabric group for a switch which has Virtual Fabrics enabled, include the fc_virtual_fabric_id configuration option and fc_southbound_protocol configuration option set to HTTP or HTTPS in the fabric group. Zoning on VF enabled fabric using SSH southbound protocol is not supported.

System requirements¶

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.

Cisco Fibre Channel Zone Driver¶

Cisco Fibre Channel Zone Driver automates the zoning operations through SSH. Configure Cisco Zone Driver, Cisco Southbound connector, FC SAN lookup service and Fabric name.

Set the following options in the cinder.conf configuration file.

[fc-zone-manager]
zone_driver = cinder.zonemanager.drivers.cisco.cisco_fc_zone_driver.CiscoFCZoneDriver
fc_san_lookup_service = cinder.zonemanager.drivers.cisco.cisco_fc_san_lookup_service.CiscoFCSanLookupService
fc_fabric_names = CISCO_FABRIC_EXAMPLE
cisco_sb_connector = cinder.zonemanager.drivers.cisco.cisco_fc_zone_client_cli.CiscoFCZoneClientCLI

Description of cisco zoning manager configuration options
Configuration option = Default value	Description
[fc-zone-manager]
`cisco_sb_connector` = `cinder.zonemanager.drivers.cisco.cisco_fc_zone_client_cli.CiscoFCZoneClientCLI`	(StrOpt) Southbound connector for zoning operation

Configure SAN fabric parameters in the form of fabric groups as described in the example below:

Description of cisco zoning fabrics configuration options
Configuration option = Default value	Description
[CISCO_FABRIC_EXAMPLE]
`cisco_fc_fabric_address` =	(StrOpt) Management IP of fabric
`cisco_fc_fabric_password` =	(StrOpt) Password for user
`cisco_fc_fabric_port` = `22`	(PortOpt) Connecting port
`cisco_fc_fabric_user` =	(StrOpt) Fabric user ID
`cisco_zone_activate` = `True`	(BoolOpt) overridden zoning activation state
`cisco_zone_name_prefix` = `None`	(StrOpt) overridden zone name prefix
`cisco_zoning_policy` = `initiator-target`	(StrOpt) overridden zoning policy
`cisco_zoning_vsan` = `None`	(StrOpt) VSAN of the Fabric

Note

Define a fabric group for each fabric using the fabric names used in fc_fabric_names configuration option as group name.

The Cisco Fibre Channel Zone Driver supports basic and enhanced zoning modes.The zoning VSAN must exist with an active zone set name which is same as the fc_fabric_names option.

System requirements¶

Cisco MDS 9000 Family Switches.

Cisco MDS NX-OS Release 6.2(9) or later.
