Cisco SME Best Practices
This chapter describes Cisco Storage Media Encryption best practices. You can avoid problems when
configuring Cisco SME if you observe the best practices described in this chapter.
Overview of Best Practices
Best practices are the recommended steps you should take to ensure the proper operation of Cisco SME.
We recommend the following best practices for Cisco SME configurations:
• General Practices, page 8-1
• Cisco SME Configuration Practices, page 8-1
• Cisco KMC Practices, page 8-2
• Fabric Management Practices, page 8-2
General Practices
• Maintain a consistent Cisco NX-OS release across all your Cisco MDS switches.
• Refer to the“Planning For Cisco SME Installation” appendix for preconfiguration information and
procedures.
• Enable system message logging. For information on system messages, refer to the Cisco MDS 9000
Family Troubleshooting Guide.
• Refer to the release notes for your Cisco SAN-OS or NX-OS release for the latest features,
limitations, and caveats.
Cisco SME Configuration Practices
• Troubleshoot any new configuration changes after implementing the change.
• Save all configuration changes on all switches in the cluster for correct cluster operation.
• When designing your backup environment, consider that Cisco SAN-OS or NX-OS supports one
cluster per switch.
• For configuration changes to Cisco SME tape groups, it is recommended that the backup application
is quiesced during the configuration change.
