If you add volumes and the available amount of volume capacity exceeds
the licensed capacity, Capacity Insufficient will be displayed in Status in
the License Key window. In this case, you need to purchase the additional
license to cover the capacity shortage within 30 days. For details on the
licensed capacity, see Licensed Capacity.
If you use Dynamic Provisioning, the licensed capacity might become
insufficient even though you did not add any volumes. When you use
Dynamic Provisioning, see the Dynamic Provisioning User’s Guide for
details on the license capacity.
• If the term key has expired, you can install program product option with
another license key.
When the term key has expired, Not Installed is displayed in the Status
in the License Key window. You can install the temporary key, the term key,
the emergency key, or the permanent key to the program product option in
this status.
• When the license key of a program product (A) expires, the license key of
the program product (B) which requires the expired program product (A)
will be also disabled.
In this case, Not Enough is displayed in the Status of the program
product (B) in the License Key window.
Emergency Key
An emergency license key is used in situations where the temporary key or the
term key is set to expire in the near future and the user cannot get the
permanent key in time because of special circumstances (for example, a
licensed server has crashed or there are problems with the communication
infrastructure). An emergency key may also be used when a user who does
not intend to purchase the option needs to undo a configuration change that
was made during the lifetime of the temporary key or the term key.
• An emergency key is effective for 30 days.
If you forcibly install an emergency key to an option that has already the
permanent key or the term key, the license of that option will expire in 30
days.
• When the license key of a program product expires, the license key of the
program product which requires the expired program product will be also
disabled.
Licensed Capacity
The licensed capacity is volume capacity which you are licensed to use with
the program product option. You need to estimate the amount of volume
capacity which you want to use with the program product option before you
purchase the permanent key or the term key. The licensed capacity has three
types depending on the program product option.
