def _CheckNodeHasSecondaryIP(lu, node, secondary_ip, prereq): ¶

Ensure that a node has the given secondary ip.

Parameters
lu:`LogicalUnit`	the LU on behalf of which we make the check
node:`objects.Node`	the node to check
secondary_ip:string	the ip to check
prereq:boolean	whether to throw a prerequisite or an execute error
Raises
`errors.OpPrereqError`	if the node doesn't have the ip, and prereq=True
`errors.OpExecError`	if the node doesn't have the ip, and prereq=False

def _CheckOutputFields(fields, selected): ¶

Checks whether all selected fields are valid according to fields.

def _DecideSelfPromotion(lu, exceptions=None): ¶

Decide whether I should promote myself as a master candidate.

def _GetNodeInstances(cfg, node_uuid): ¶

Returns a list of all primary and secondary instances on a node.

def _GetNodeInstancesInner(cfg, fn): ¶

Undocumented

def _GetNodePrimaryInstances(cfg, node_uuid): ¶

Returns primary instances on a node.

def _GetNodeSecondaryInstances(cfg, node_uuid): ¶

Returns secondary instances on a node.

def _GetStorageTypeArgs(cfg, storage_type): ¶

Returns the arguments for a storage type.
