• Add the licensed capacity of the meter key.
• Add the licensed capacity of the permanent key.
• Decrease the used capacity.
Grace Period status with meter key
With the license of the meter key, the amount of the licensed capacity of the permanent key exceeding
the used capacity is subtracted. In "Example of licensed capacity of permanent key + licensed capacity of
meter key < used capacity" in
Using the meter key ,
Grace Period
is displayed in the status field of the
License Key window. The duration of the Grace Period is 30 days. The license for the deficient amount
must be purchased within the 30 days.
In the Grace Period term, the operation can be performed in the same manner as the Installed status.
However, as the license capacity of the meter key continues to be subtracted, the subtraction continues
even if the license capacity of the meter key becomes a negative value. For example:
• If the licensed capacity of the meter key is -10 TB and 20 TB of license capacity is installed, the
remaining licensed capacity becomes 10 TB.
• If the licensed capacity is a negative value and more licensed capacity of the permanent key than the
used capacity is installed, the meter license is deleted.
If the license key for the deficient amount of capacity is not installed within the 30 days, the status
changes to
Not Enough License
, and the software application is disabled. If a permanent key with
more licensed capacity than the used capacity is installed, the meter license is deleted.
Estimating licensed capacity
The licensed capacity is volume capacity that you are licensed to use with the software application. You
need to estimate the amount of capacity which you want to use with the software application before you
purchase the permanent key, the term key, or the meter key.
Software and licensed capacity
Three licensed capacity types are available. The one you choose depends on the software. The following
table shows the licensed capacity types:
Table 19: Licensed capacity types
Type Description
Used capacity The licensed capacity is estimated by using one of the following capacities, which
depends on the software product.
• Normal volumes (LDEVs)
• External volumes mapped to the storage system
• Pools
Mounted capacity/
Usable capacity The licensed capacity is estimated using the capacity of all the LDEVs in the
storage system.
Unlimited capacity You can use the software regardless of the volume capacity.
