 def list_attached_partitions(self, name=None, status=None):
 """ Return the partitions to which this storage group is currently attached, optionally filtered by partition name and status. Authorization requirements: * Object-access permission to this storage group. * Task permission to the "Configure Storage - System Programmer" task. Parameters: name (:term:`string`):
 Filter pattern (regular expression) to limit returned partitions to those that have a matching name. If `None`, no filtering for the partition name takes place. status (:term:`string`):
 Filter string to limit returned partitions to those that have a matching status. The value must be a valid partition status property value. If `None`, no filtering for the partition status takes place. Returns: List of :class:`~zhmcclient.Partition` objects representing the partitions to whivch this storage group is currently attached, with a minimal set of properties ('object-id', 'name', 'status'). Raises: :exc:`~zhmcclient.HTTPError` :exc:`~zhmcclient.ParseError` :exc:`~zhmcclient.AuthError` :exc:`~zhmcclient.ConnectionError` """
