Configuring Auto Fabric for bare metal

Bare-metal configuration requires a unique WWN-to-RBridge ID mapping, which informs the cluster which RBridge ID can be assigned to a joining bare-metal switch. Each time you want to add a bare-metal switch to a cluster, you need to create a new WWN-RBridge-ID mapping that is unique for the cluster.

The cluster must be a logical chassis cluster, and this configuration must be executed the principal node in that cluster. Run the show vcs command on the bare-metal switch to obtain its WWN.

To create a bare-metal configuration, do the following:

  1. Enter the configuration command to enter global configuration mode:
    switch# configure
  2. Enter the preprovision command to map an RBridge ID to the WWN name of the bare-metal switch you will be adding to the cluster. This can be any RBridge ID that is not currently assigned within the cluster. For example, if the WWN of the bare-metal switch is 10:11:12:13:14:15:16:17, and you wish to assign an RBridge of of 5 to the bare-metal switch, you would enter:
    switch (config)# preprovision rbridge-id 5 wwn 10:11:12:13:14:15:16:17
    If you want to change this Rbridge-ID assignment after you have issued the above command, refer to the Changing RBridge ID-to-WWN Mapping for Bare Metal configuration.
  3. Physically connect the bare-metal switch to the cluster. The bare-metal switch obtains its VCS ID, VCS mode, Virtual-Fabric state, and RBridge ID from its neighbor, then the bare-metal switch automatically reboots. After reboot is completed, the switch is now bare-metal disabled. The cluster then verifies that the RBridge ID of the bare-metal switch is unique to the cluster and to the RBridge-ID-to_WWN mapping, then adds the switch to the cluster.

    if a node is part of cluster but is in offline state, and the node was baremetal-enabled, then the node obtains its RBridge-ID, VCS ID, and configuration from the cluster.

Each time you want to add a bare-metal switch, you need to repeat this procedure with the WWN name of the bare-metal switch by mapping it to an RBridge ID that is not currently assigned within the cluster.
