Uninstalling the OIM tools

Run this script to roll back all modifications made to the OIM, such as configured local repositories, provisioning tools, and telemetry configurations.

To run the script:

cd utils
ansible-playbook oim_cleanup.yml

To skip the deletion of the configured local repositories (stored in repo_store_path and xCAT repositories), run:

ansible-playbook oim_cleanup.yml –-skip-tags downloads

To delete the changes made by local_repo.yml while retaining the repo_store_path folder, run:

ansible-playbook oim_cleanup.yml -–tags local_repo  --skip-tags downloads

To delete the changes made by local_repo.yml including the repo_store_path folder, run:

ansible-playbook oim_cleanup.yml –-tags local_repo

Note

After you run the oim_cleanup.yml playbook, ensure to reboot the OIM node.

Caution

  • When re-provisioning your cluster (that is, re-running the discovery_provision.yml playbook) after a clean-up, ensure to use a different admin_nic_subnet in input/provision_config.yml to avoid a conflict with newly assigned servers. Alternatively, disable any OS available in the Boot Option Enable/Disable section of your BIOS settings (BIOS Settings > Boot Settings > UEFI Boot Settings) on all target nodes.

  • On subsequent runs of discovery_provision.yml, if users are unable to log into the server, refresh the ssh key manually and retry.

    ssh-keygen -R <node IP>
