Removing a SME interface from a cluster means that the interface is still up but it is not bound to a cluster.
In the existing MDS 9000 Family platform, a module can be replaced with another module and there is no change in configuration. In SME, due to security reasons, when an MSM-18/4 module or a SSN-16 module is configured as part of a cluster, it cannot be replaced with another MSM-18/4 or a SSN-16 module, otherwise, the SME interface will come up in an inactive state. The correct procedure is to remove the SME interface from the cluster and re-add the interface into the cluster. This procedure should be followed to bring a new MSM-18/4 or a SSN-16 module into the cluster.
Note You must enter the copy running-config startup-config CLI command after adding or deleting interfaces or switches from a cluster.
Before you remove an SME interface, you must close the SME interface using the CLI or DCNM-SAN.
To remove (unbind) a SME interface from an existing SME configuration, follow these steps:
1. From the SME navigation pane, click Members to display the switches and interfaces already configured in the cluster.
2. Select a SME interface and click Remove.
3. Click OK to delete (unbind) the interface.
4. View the notification that the interface was removed.
Note The interface is removed while the node remains defined.
