• The configuration settings that were made before the temporary license key expired remain
in effect and cannot be deleted.
Permanent Key
A permanent key is purchased if you want to use program product options indefinitely. A permanent key
has an upper limit of volume capacity that can be used for each program product option.
Before purchasing the permanent key, you need to estimate the volume capacity that can be used for
the program product option. This volume capacity is called the licensed capacity. If you add volumes
and the available amount of volume capacity exceeds the licensed capacity, Capacity Insufficient is
displayed in the 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 ” on page 43.
If you use HP StorageWorks XP Thin Provisioning Software, the licensed capacity might become
insufficient even though you did not add any volumes. When you use XP Thin Provisioning, see the HP
StorageWorks XP24000/XP20000 Thin Provisioning User’s Guide for details on the license capacity.
Term Key
A term key is purchased if you want to use the program product option for a specified number days.
• The term key is available for 365 days.
• You can set the term key to enable or disable each program product option.
Note that only the days when the program product option is enabled with the term key are
deducted from the 365 days when the date changes.
For example, if the term key is set to enable for 150 days and set to disable for 100 days after
you installed the term key, there are 215 remaining days (365 days minus 150 days), although
250 days have passed in total.
You can delay the expiration of the term key by setting the term key to disable when you are not
using the program product option.
• The term key, which is the same as the permanent key, has a limit for the volume capacity that
can be used for each program product option.
If you add volumes and the available amount of volume capacity exceeds the licensed capacity,
Capacity Insufficient will be displayed in the Status in the License Key window. In this case, you
need to purchase an additional license to cover the capacity shortage within 30 days. For details
on the licensed capacity, see “ Licensed Capacity ” on page 43.
If you use XP Thin Provisioning, the licensed capacity might be insufficient even if you did not add
any volumes. When you use XP Thin Provisioning, see the HP StorageWorks XP24000/XP20000
XP Thin Provisioning User’s Guide for details on the license capacity.
• If the term key has expired, you can install a 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 for a program product expires, the license key for a program product which
requires the expired program product will be also disabled.
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.
Note: If you forcibly install an emergency key for an option that already has a permanent key or term key,
the license for that option will expire in 30 days.
