Goal

This document is intended to provide the steps to be taken to remove a node from the Oracle cluster. The node itself is unavailable due to some OS issue or hardware issue which prevents the node from starting up. This document will provide the steps to remove such a node so that it can be added back after the node is fixed.

The steps to remove a node from a Cluster is already documented in the Oracle documentation at

Version	Documentation Link
10gR2	https://download.oracle.com/docs/cd/B19306_01/rac.102/b14197/adddelunix.htm#BEIFDCAF
11gR1	https://download.oracle.com/docs/cd/B28359_01/rac.111/b28255/adddelclusterware.htm#BEIFDCAF

This note is different because the documentation covers the scenario where the node is accessible and the removal is a planned procedure. This note covers the scenario where the Node is unable to boot up and therefore it is not possible to run the cluster-ware commands from this node.
