<div dir="ltr">Hi Martin and Team,<div>Following to my questions of adding new compute onto existing overcloud, If the new compute server is not the same type (existing running on blade server) where it may be rack mount type, what are the changes I should make to all yaml files related? I foreseen tricky especially the nic layout is different between blade and rack mount type. </div><div>Pls advise anyone facing the same scenario....
