How to destroy vertica cluster (removing last node from the cluster)

Question

Hi

Let's say I want to completely remove vertica cluster. I have successfully removed all the other nodes, dropped all databases on all nodes.
But I can't seem to destroy this cluster, I have tried removing remainder of node from that cluster, but it can't do this since:Error: No machines will be included in the cluster!

[root@dev-dc1-verticadb ~]# /opt/vertica/sbin/install_vertica --remove-hosts dev-dc1-verticadb --rpm vertica-9.2.1-0.x86_64.RHEL6.rpm --data-dir /vertica
  Vertica Analytic Database 9.2.1-0 Installation Tool

Validating options...

Mapping hostnames in --remove-hosts (-R) to addresses...
          dev-dc1-verticadb              => 10.51.2.66
  Error: No machines will be included in the cluster!
  Hint: provide --hosts.
