def CheckPrereq(self):
overrides ganeti.cmdlib.base.LogicalUnit.CheckPrereq

Check prerequisites.

This checks:

  • the node exists in the configuration
  • OOB is supported

Any errors are signaled by raising errors.OpPrereqError.

def Exec(self, feedback_fn):
overrides ganeti.cmdlib.base.LogicalUnit.Exec

Execute OOB and return result if we expect any.

def ExpandNames(self):
overrides ganeti.cmdlib.base.LogicalUnit.ExpandNames

Gather locks we need.
