Converting to a fabric cluster while preserving configuration

There is no specific command that can convert a logical chassis cluster to a fabric cluster while preserving current configurations, but you can accomplish this task as follows:

  1. Make sure all the nodes that you intend to transition from a logical chassis cluster to a fabric cluster are online. Run either the show vcs or show vcs detail command to check the status of the nodes.
  2. Back up the configurations of all nodes in the cluster by running the copy rbridge-running-config rbridge-id command on each node and saving the configuration to a file on a remote FTP, SCP, SFTP, or USB location:

    copy rbridge-running-config rbridge-id rbridge-id location_configfilename

    This command copies both the global and local configurations for the specified RBridge ID.

    NOTE
    FTP is not supported for collecting configuration backups for the Brocade VDX 2740 or Brocade VDX 2746.
  3. From the principal node of the logical chassis cluster, transition the entire cluster to fabric cluster mode (using the default configuration) by running the following command:

    no vcs logical-chassis enable rbridge-id all default-config

    The nodes automatically reboot in fabric cluster mode. Plan for some down time for this transition.

  4. Run either the show vcs or show vcs detail command to check that all nodes are online and now in fabric cluster (listed as "Local-only" in the command output) mode.
  5. Restore the global and local configurations on each individual node for which you backed up these configurations by running the following command on each node:

    copy location_configfilename running-config

  6. To cause this downloaded configuration to be persistent for a node, run the copy running-config startup-config command.
