Using the permanent key
You can purchase the permanent key to use a software application indefinitely. You must estimate a licensed capacity required for using the software application and purchase a license key for the amount of the required capacity.
If insufficient license capacity is installed, Not Enough License displays in the status field of the License Keys window, and the software application is not enabled.
If the capacity of the usable volume exceeds the licensed capacity while the storage system is running, for example, an LDEV was additionally installed, Grace Period displays in the status field of the License Keys window. You can continue to perform the same operations, but the deficient amount of license must be purchased within 30 days.
