HP XP Performance Advisor Software - Manual (Page 37)

Exceeding Permanent licensed capacity and grace period
When the internal raw disk capacity of an XP disk array or the usable capacity of an XP7 disk
array exceeds the Permanent licensed capacity, HP XP7 Performance Advisor switches to the grace
period of 60 days for that particular disk array.
The License Status for such XP or XP7 disk arrays displays Capacity Insufficient in the View License
Status section. The following informational message appears under Comments:
Array capacity exceeds licensed Capacity which was detected on month, day, year. Grace Period
expires on month, day, year. Please purchase the required Performance Advisor licenses now to
continue using Performance Advisor on this Array.
where:
month, day, year is the date till when the grace period is valid.
To continue monitoring the internal raw disk capacity, purchase the required HP XP7 Performance
Advisor LTUs and generate a Permanent license before the grace period expires.
Similarly, to continue monitoring the usable capacity, you can generate a Permanent license or
appropriate TB-Days of Meter based Term license based on your requirement. HP XP7 Performance
Advisor verifies the XP7 disk array usable capacity whenever you perform or schedule outband
mode of configuration data collection.
Example scenario 7
Consider the following points:
1. An XP7 disk array has a usable capacity of 50TB.
2. A Permanent license is installed on 11/20/2010 to monitor the 50TB usable capacity.
3. Due to a surge in storage requests, another 25TB usable capacity is added on 11/30/2010
for a duration of five days.
4. As the additional usable capacity is greater than the Permanent licensed capacity, HP XP7
Performance Advisor enters 60 days grace period.
Because this is a short term unplanned surge in storage requests, you can install TB-Days of Meter
based Term license to monitor the additional usable capacity for the specified duration. To monitor
25TB for five days (at the rate of 25TB a day), generate and install 125TB-Days on 11/30/2010.
As 125TB-Days are sufficient for five days, HP XP7 Performance Advisor ends the grace period
and updates the following fields in the License screen – License Status section:
•
After installation on 11/30/2010:
License Capacity: 50TB, +125TB-Days ◦
◦ License Status: Installed
