Cisco MDS SanOS Troubleshooting Guide -- Troubleshooting Licensing
This section describes how to manage the issues with licensing. Licensing functionality is available in all switches in the Cisco MDS 9000 Family. This functionality allows you to access specified premium features on the switch after you install the appropriate license for that feature. Licenses are supported, and enforced in Cisco MDS SAN-OS Release 1.3(1) and later.
Cisco SAN-OS requires licenses for advanced features. These licenses have two options:
- Feature-based licensing—Features that are applicable to the entire switch. You need to purchase and install a license for each switch that uses the features you are interested in. The Enterprise license is an example of a feature-based license.
- Module-based licensing—Features that require additional hardware modules. You need to purchase and install a license for each module that uses the features you are interested in. The SAN Extension over IP license is an example of a module-based license.
Chassis Serial Numbers
Licenses are created using the serial number of the chassis where the license file is to be installed. Once you order a license based on a chassis serial number, you cannot use this license on any other switch. If you use a license meant for another chassis, you may see the following system message:Error Message
LICMGR-3-LOG_LIC_INVALID_HOSTID: Invalid license hostid VDH=[chars] for feature [chars].
Explanation The feature has a license with an invalid license Host ID. This can happen if a supervisor module with licensed features for one switch is installed on another switch.
Recommended Action Reinstall the correct license for the chassis where the supervisor module is installed.
