How we can mark nodes as unavailable or does unavailable means draining the nodes?

John Paul:
It means cordon them

#3

Narendra Singh:
@John Paul Drain also makes node unavailable (SchedulingDisabled). It implicitly do the cordon command part, plus evicts the pods from the node as well.
So, if we drain instead of cordon, is the answer incorrect? Please provide links as well if any.
