connector – Connector

Brick Connector objects for each supported transport protocol.

The connectors here are responsible for discovering and removing volumes for each of the supported transport protocols.

class os_brick.initiator.connector.InitiatorConnector

static factory(protocol, root_helper, driver=None, use_multipath=False, device_scan_attempts=3, arch=None, *args, **kwargs)

Build a Connector object based upon protocol and architecture.

class os_brick.initiator.connector.ISCSIConnector(root_helper, driver=None, execute=None, use_multipath=False, device_scan_attempts=3, transport='default', *args, **kwargs)

Connector class to attach/detach iSCSI volumes.

connect_volume(connection_properties)

Attach the volume to instance_name.

Parameters

connection_properties (dict) – The valid dictionary that describes all of the target volume attributes.

Returns

dict

connection_properties for iSCSI must include: target_portal(s) - ip and optional port target_iqn(s) - iSCSI Qualified Name target_lun(s) - LUN id of the volume Note that plural keys may be used when use_multipath=True

disconnect_volume(connection_properties, device_info, force=False, ignore_errors=False)

Detach the volume from instance_name.

Parameters

• connection_properties (dict that must include: target_portal(s) - IP and optional port target_iqn(s) - iSCSI Qualified Name target_lun(s) - LUN id of the volume) – The dictionary that describes all of the target volume attributes.

• device_info (dict) – historical difference, but same as connection_props

• force (bool) – Whether to forcefully disconnect even if flush fails.

• ignore_errors (bool) – When force is True, this will decide whether to ignore errors or raise an exception once finished the operation. Default is False.

class os_brick.initiator.connector.FibreChannelConnector(root_helper, driver=None, execute=None, use_multipath=False, device_scan_attempts=3, *args, **kwargs)

Connector class to attach/detach Fibre Channel volumes.

connect_volume(connection_properties)

Attach the volume to instance_name.

Parameters

connection_properties (dict) – The dictionary that describes all of the target volume attributes.

Returns

dict

connection_properties for Fibre Channel must include: target_wwn - World Wide Name target_lun - LUN id of the volume

disconnect_volume(connection_properties, device_info, force=False, ignore_errors=False)

Detach the volume from instance_name.

Parameters

• connection_properties (dict) – The dictionary that describes all of the target volume attributes.

• device_info (dict) – historical difference, but same as connection_props

connection_properties for Fibre Channel must include: target_wwn - World Wide Name target_lun - LUN id of the volume

class os_brick.initiator.connector.LocalConnector(root_helper, driver=None, *args, **kwargs)

“Connector class to attach/detach File System backed volumes.

connect_volume(connection_properties)

Connect to a volume.

Parameters

connection_properties (dict) –

The dictionary that describes all of the target volume attributes. connection_properties must include:

• device_path - path to the volume to be connected

Returns

dict

disconnect_volume(connection_properties, device_info, force=False, ignore_errors=False)

Disconnect a volume from the local host.

Parameters

• connection_properties (dict) – The dictionary that describes all of the target volume attributes.

• device_info (dict) – historical difference, but same as connection_props

class os_brick.initiator.connector.HuaweiStorHyperConnector(root_helper, driver=None, *args, **kwargs)

“Connector class to attach/detach SDSHypervisor volumes.

connect_volume(connection_properties)

Connect to a volume.

Parameters

Returns

dict

disconnect_volume(connection_properties, device_info, force=False, ignore_errors=False)

Disconnect a volume from the local host.

Parameters

• connection_properties (dict) – The dictionary that describes all of the target volume attributes.

• device_info (dict) – historical difference, but same as connection_props
