2.12.3 Remove the Database Server from the Cluster
If you are repurposing a deployed server or reimaging a failed server, you must remove the server from the associated cluster before you reimage it. If you are reimaging the server for a different reason, skip this task and proceed with the reimaging task next.
To remove an Exadata database server from an existing Oracle Grid Infrastructure cluster, following the procedure for Deleting a Cluster Node on Linux and UNIX Systems in the Oracle Clusterware Administration and Deployment Guide.
Note:
If the server being removed has failed or is inaccessible, you can skip any steps that require running commands on that server.
