iscsi_do_export_snapshot(context, snapshot, connector)¶

Exports the snapshot.

iscsi_get_volume_stats(refresh=False)¶

Get volume status.

If ‘refresh’ is True, run update the stats first.

iscsi_initialize_connection(volume, connector)¶

iscsi_initialize_connection_snapshot(snapshot, connector, **kwargs)¶

Allow connection to connector and return connection info.

Parameters:	snapshot – The snapshot to be attached connector – Dictionary containing information about what is being connected to.
Returns conn_info:
	A dictionary of connection information. This can optionally include a “initiator_updates” field.

iscsi_terminate_connection(volume, connector)¶

iscsi_terminate_connection_snapshot(snapshot, connector, **kwargs)¶

Disallow connection from connector.

migrate_volume(context, volume, host)¶

remove_export(context, volume)¶

remove_export_snapshot(context, snapshot)¶

Removes an export for a snapshot.
