Returns a string with a locally unique name of the parent of the device, or undef if there is no parent

my $xml = $dev->get_xml_description()

Returns an XML document containing a complete description of the storage dev's configuration

$dev->reattach()

Rebind the node device to the host OS device drivers.

$dev->dettach()

Unbind the node device from the host OS device driver

$dev->reset()

Reset the node device. The device must be unbound from the host OS drivers for this to work
