Cisco MDS SanOS Troubleshooting Guide -- Troubleshooting Licensing
From DocWiki
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.
License Overview
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.
 | Note: | The Cisco MDS 9216i switch enables SAN Extension features on the two fixed IP services ports only. The features enabled on these ports are identical to the features enabled by the SAN Extension over IP license on the14/2-port Multiprotocol Services (MPS-14/2) module. If you install a module with IP ports in the empty slot on the Cisco MDS 9216i, a separate SAN Extension over IP license is required to enable related features on the IP ports of the additional module. |
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 MessageLICMGR-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.
