Disable TLS secure channel on an NVMe host before reverting

Contributors netapp-mwallis

Beginning with ONTAP 9.16.1, you can configure TLS secure channel for NVMe/TCP connections. If you have configured TLS secure channel for NVMe/TCP connections in ONTAP 9.16.1 or later releases, you need to disable the TLS configuration on the NVMe hosts before you revert ONTAP to a version that does not support TLS secure channel for NVMe/TCP.

Steps

  1. Remove the TLS secure channel configuration from the host:

    vserver nvme subsystem host unconfigure-tls-for-revert -vserver <svm_name> -subsystem <subsystem> -host-nqn <host_nqn>

    This command removes the host from the subsystem, and then recreates the host in the subsystem without the TLS configuration.

  2. Verify that TLS secure channel is removed from the host:

    vserver nvme subsystem host show
