Decommissioning and Recommissioning Switches

This chapter contains the following sections:

Decommissioning and Recommissioning Switches

To decommission and recommission all the nodes in a pod, perform this procedure. One use case for this is to change the node IDs to a more logical, scalable numbering convention.

Procedure

Step 1

Decommission the nodes in the pod by following these steps for each one:

  1. Navigate to Fabric > Inventory and expand the Pod.

  2. Select the switch, right-click on it, and choose Remove from Controller.

  3. Confirm the action and click OK.

    The process takes about 10 minutes. The node is automatically wiped and reloaded. In addition, the node configuration is removed from the controller.

  4. If a decommissioned node had the port profile feature deployed on it, some port configurations are not removed with the rest of the configuration. It is necessary to manually delete the configurations after the decommission for the ports to return to the default state. To do this, log on to the switch, run the setup-clean-config.sh script, and wait for it to run. Then, enter the reload command.

Step 2

When all the switches have been decommissioned from the pod, verify they are all physically connected and booted in the desired configuration.

Step 3

Perform the following actions to recommission each node.

Note

 

Before recommissioning a node with a port profile configuration as a new node, for the 6.0(7) and earlier releases, you must run the setup-clean-config.sh script, or for the 6.0(8) and later releases you must run the setup-clean-config.sh -d script to restore the port configuration to the default settings.

  1. Navigate to Fabric > Inventory, expand Quick Start, and click Node or Pod Setup.

  2. Click Setup Node.

  3. In the Pod ID field, choose the pod ID.

  4. Click the + to open the Nodes table.

  5. Enter the node ID, serial number, Switch name, TEP Pool ID, and Role (leaf or spine) for the switch.

  6. Click Update.

Step 4

Verify the nodes are all set up by navigating to Fabric > Inventory > Fabric Membership.

What to do next

If the pod is one of the pods in a multipod topology, reconfigure multipod for this pod and the nodes. For more information, see Multipod in the Cisco APIC Layer 3 Networking Configuration Guide.
