Licensing High Availability Chapter 10 Obtaining and Installing Licenses Send documentation comments to [email protected] Table 10-1 Feature-Based Licenses (continued) Feature License Data Mobility Manager (DMM) • DMM_FOR_SSM_PKG Features • The Cisco MDS 9000 DMM feature runs on the Storage Service Module (SSM) in a MDS series switch. This license will activate Data Mobility Manager (DMM) for Storage Service Module. • Online migration of heterogenous arrays • Simultaneous migration of multiple LUNs • Unequal size LUN migration • Rate adjusted migration • Verification of migrated data • Secure erasure of migrated data • Dual fabric support Note License packages for Cisco DMM (Cisco Data Mobility Manager) and Cisco SME (Cisco Storage Media Encryption) are documented in the Cisco MDS Data Mobility Manager Configuration Guide, and the Cisco Storage Media Encryption Configuration Guide. Licensing High Availability As with other Cisco MDS SAN-OS features, the licensing feature also maintains the following high availability standards for all switches in the Cisco MDS 9000 Family: • Installing any license in any switch is a nondisruptive process. • Installing a license automatically saves a copy of permanent licenses to the chassis in all switches. • Enabling a license feature without a license key starts a counter on the grace period. You then have 120 days to install the appropriate license keys or disable the use of that feature. If at the end of the 120-day grace period the switch does not have a valid license key for the feature, the feature is automatically disabled by the switch. Directors in the Cisco MDS 9500 Series have the following additional high availability features: • The license software runs on both supervisor modules and provides failover protection. • The license key file is mirrored on both supervisor modules. Even if both supervisor modules fail, the license file continues to function from the version that is available on the chassis. Options to Install a License If you have purchased a new switch through either your reseller or through Cisco Systems, you can: • Obtain a factory-installed license (only applies to new switch orders). • Perform a manual license installation (applies to existing switches). 10-8 Cisco MDS 9000 Family CLI Configuration Guide OL-16184-01, Cisco MDS SAN-OS Release 3.x
