= Resolving a fencing failure in TNF

[role="_abstract"]
You must manually intervene when a cluster cannot automatically fence a failed node. Use the following procedure to safely power off the unresponsive hardware and clear the `UNCLEAN (offline)` state to allow the surviving node to resume cluster operations.

If the `pcs status` command shows the failed node as `UNCLEAN (offline)`, the automated fencing sequence did not succeed, and manual recovery is required.

.Procedure

. Verify that the failed node is powered off using the BMC console or physical inspection.

. Confirm the fencing manually by running the following command:
+
[source,terminal]
----
$ oc debug node/<surviving-node> -- chroot /host pcs stonith confirm <failed_node_name> --force
