What are the effects on the system when my license expires?
If the License period expires, normal share access and other items that provide data access will continue to work but cannot be changed with an expired license.
Advanced features like Replication, Backup Policies and Snapshotting that perform a license check before triggering do require a valid license key to run. These features will stop running without a valid license.
Adding Licenses will have no impact on client access for shares.
To add a license use the QuantaStor License Manager:
Use the License Manager to add new OS Nexus QuantaStor license keys.
There are two methods available to activate license keys which have been added to the License Manager.
1. If the QuantaStor system has an active connection to the internet you can Activate Online.
The License Manager can also be used to remove expired license keys.
