Cisco MDS 9000 Family Storage Media Encryption Configuration Guide
OL-18091-01, Cisco MDS NX-OS Release 4.x
Chapter 2 Getting Started
Cisco SME Configuration Restrictions
Cisco SME configuration tasks listed below provide an overview of the basic Cisco SME configuration
process. Complete the Cisco SME configuration tasks on the switch with an installed MSM-18/4 module
or on a Cisco MDS 9222i switch.
Cisco SME basic configuration tasks include the following:
• Create the Cisco SME interface (Chapter 3, “Cisco SME Interface Configuration”)
• Create a cluster for Cisco SME (Chapter 4, “Cisco SME Cluster Management”)
• Add the interfaces to the cluster (Chapter 4, “Cisco SME Cluster Management”)
• Create a tape group (including selecting the backup server and discovering backup libraries)
(
Chapter 5, “Cisco SME Tape Configuration”)
For details about configuration procedures using the CLI, see Chapter 7, “Using the Command Line
Interface to Configure SME.”
Saving Cisco SME Cluster Configurations
Caution Configuration changes must be saved on all switches in the cluster for correct cluster operation. This
must be done after the initial cluster creation and after all subsequent changes are made to the cluster
configuration.
You must save configuration changes whenever switches or interfaces are added or deleted from a
cluster.

FICON Restriction
Cisco SME is not supported on FICON devices and Cisco SME cluster devices cannot be part of a

You cannot configure Cisco SME and iSCSI on the same Cisco MDS MSM-18/4 module as SME uses
the iSCSI port indices.
