When you install a license key, it is automatically enabled and the timer on the license starts at that time. To preserve time on a term key license, you can disable the license without uninstalling it. When you need to use the software again, you can re-enable the license.
You can use software with licensed capacity for a term key by installing a term key and overwriting a permanent key as long as the term key is valid. If the term key expires while the system is being used and the capacity needed for the operation is insufficient, operations that you can perform are limited. In this case, a SIM that indicates the term key expiration (reference code 7ff7xx) is output on the Alerts tab in the Storage Systems window.
