There are not much details on the impact of a cluster lock down on Nutanix. Documentation explains how to achieve this, by disabling remote password logging and deleting all public keys. However, nothing what is then no more possible to achieve.
As I understand, please correct me if I'm wrong (and confirm if I'm right), is that cluster communication is not made through SSH, neither is configuration from the Web Console. Therefore, locking down the cluster just prevents to login through SSH, and hence disallow usage of allssh commands for example. In that case, the only way to manage the cluster is to access it from Prism. Is all this correct ? Anything other impact ?
