3. Run the following command to convert all RBridge IDs: no vcs logical-chassis enable rbridge-id
all default-config.
NOTE
To convert just one RBridge ID, specify the ID as shown in the following example: no vcs logical-
chassis enable rbridge-id rbridge-id 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.
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.
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.
Adding a node to a logical chassis cluster
Nodes can be dynamically added to an existing logical chassis cluster. If the proper physical
connections exist between the existing logical chassis cluster and the new node, the process is
automatic.
Log into the new node and run the vcs logical-chassis enable command with the desired options.
You must assign the new node the VCS ID of the existing cluster.
You can run the show vcs command to verify that the status of the added node is "online."
Removing a node from a logical chassis cluster
If the no vcs enable command is executed on a switch that is currently in logical chassis cluster
mode, the switch boots in standalone mode. (Only the Brocade VDS 6710-54, 6720, and 6730 support
