This is an interface to the root of the configFS object tree. Is allows one to start browsing Target and StorageObjects, as well as helper methods to return arbitrary objects from the configFS tree.

__str__(self)
str(x)
 
dump(self)
Returns a dict representing the complete state of the target config, suitable for serialization/deserialization, and then handing to restore().

Method Details [hide private]

__init__(self)
(Constructor)

 

Instanciate an RTSRoot object. Basically checks for configfs setup and base kernel modules (tcm)

Overrides: object.__init__

__str__(self)
(Informal representation operator)

 

str(x)

Overrides: object.__str__
(inherited documentation)

dump(self)

 

Returns a dict representing the complete state of the target config, suitable for serialization/deserialization, and then handing to restore().

Overrides: node.CFSNode.dump

restore(self, config, clear_existing=False)

 

Takes a dict generated by dump() and reconfigures the target to match. Returns list of non-fatal errors that were encountered.
