In these situations, the steps below will provide the ability to successfully update the license key :

1. Open Add/Remove Programs and browse to Veritas/veritas Storage Foundation 5.x Server Components
2. Click Change and then choose License Management
3. You will see the old, temporary key in there. Ignore it and just add the new permanent key.
4. After you add the permanent key, you should just see the new permanent key in License Management.
5. Complete the License Management wizard.

It is necessary to restart SFW/HA services for the License key to take effect. It would be best to restart the node when available but if this is not possible then the following commands will restart the correct services without having to reboot the node.

From a Windows Command line, run the following two commands:  These steps restart the Storage Agent so that the Permanent key will take effect.
 

 Note: If MSCS/WFC clustering is using Veritas Dynamic Disk Groups running the commands above will cause an outage if the clustered application is running on the node. In these cases it is necessary to either wait for a window to restart the node or to fail the application over to another node in the cluster.
 

If VCS cluster is being used it is necessary to save and close the cluster configuration then restart HAD (as well as using the commands above to restart the Storage Agent). The following commands will save and close the cluster configuration,  stop the cluster while leaving the clustered application running then restart the cluster.
