Issue"Single Mode Aggregation" error when attempting to start aggregation on an RSA NetWitness Concentrator after an upgrade.

After upgrading your RSA NetWitness concentrator to 9.5.5.9 or 9.5.5.10, you may see an error message similar to the following in the concentrator log when trying to unsuccessfully start Aggregation:

263038 2011-May-12 10:16:34 Concentrator failure The server is only configured for single mode aggregation

CauseThis is likely due to an issue with the license that is currently applied to the concentrator.
ResolutionContact RSA Support and request a new license for your concentrator and include the device's Computer ID.  Once the new license is imported and applied, you should be able to start aggregation on your concentrator.
