HP XP P9500 Storage - Manual (Page 66)

You can also use the emergency key if the configuration of the software application that is installed
by the temporary key remains in the changed status and cannot be restored to the original status.
For example, if you do not plan to purchase the software application with the emergency key.
CAUTION:
•
If the emergency key is installed in the software application in which the permanent key, term
key, or meter key is installed, the effective term of the license key is 30 days. However, because
the emergency key can be reinstalled during the effective term, the effective term can be
restored to 30 days.
•
In other scenarios, the emergency key can be installed only once.
Using the meter key
•
The permanent license must be already installed.
•
The meter license is used if the used amount exceeds the permanent licensed capacity.
•
The expiration date is calculated from the amount of the used capacity exceeding the permanent
license capacity and the remaining meter licensed capacity. On the other hand, if the used
capacity is within the permanent licensed capacity, the meter license is not used, and the
expiration date is not displayed.
•
Meter licensed capacity is checked daily at 13:00, based on the SVP clock. At this time, one
day is deducted from the number of TB-Days. If others are using Remote Web Console during
that time, the License Key window update might be delayed.
•
Unlike a term key, the license of a meter key cannot be disabled.
•
The meter license after removal cannot be reinstalled. The remaining TB/Day license will be
forfeited.
•
The license capacity of software applications such as Auto LUN is based on the mounted
capacity. To stop the meter license capacity from being reduced when used with one of these
software applications cannot be used.
Calculating the effective term of the meter key
The effective term of the meter key is calculated from the following three types of capacities.
•
The used capacity.
•
The licensed capacity of the permanent key.
•
The remaining licensed capacity of the meter key.
The calculation formula is as follows.
Effective term = remaining licensed capacity of meter key / used capacity
- licensed capacity of permanent key
If the used capacity is within the licensed capacity of the permanent key, the license of the meter
key is not used, and the expiration date for use is not displayed. An example is shown next.
Example of licensed capacity of permanent key >= used capacity
The meter license is not used. Therefore, the licensed capacity of the meter key is not subtracted.
Meter
is displayed in the key type field, and Installed is displayed in the status field.
