NOTE: Reduction or negative counting is only applicable for the installed TB-Days. It is not
applicable for Permanent licenses.
After 60 days grace period, PA stops configuration data collection for any additional physical usable
capacities. It continues performance data collection for the existing physical usable capacity.
Example scenario 8
Consider the following points:
1. An XP7 disk array has a physical usable capacity of 50TB.
2. A Permanent license is installed on 11/23/2010 to monitor the 50TB physical usable capacity.
3. Due to a surge in storage requests around 11/30/2010, another 10TB physical usable capacity is
added for a duration of five days.
4. Because this is a short term unplanned request, it is addressed by installing 50TB-Days of Meter
based Term license on 11/30/2010.
5. After the installed TB-Days are consumed by 12/04/2010 and extra TB-Days are not added to monitor
the 10TB physical usable capacity, PA does the following:
a. Enters the grace period after 1:00 PM on 12/04/2010 and 0TB-Days are available. The following
fields are updated with the latest TB-Days data:
• License Capacity: Displays 50TB, 0TB-Days
• License Status: Capacity Insufficient
• Term (Days): 0
• End Date: Expired
b. Begins reducing the installed TB-Days by 10TB every day starting from 12/05/2010:
• On 12/05/2010, 0TB-Days are reduced to –10TB-Days
• On 12/06/2010, –10TB-Days are reduced to –20TB-Days
• On 12/06/2010, –20TB-Days are reduced to –30TB-Days
• On 12/07/2010, –30TB-Days are reduced to –40TB-Days
• On 12/08/2010, –40TB-Days are reduced to –50TB-Days
• On 12/09/2010, –50TB-Days are reduced to –60TB-Days
6. The reduction in TB-Days continues till you install the appropriate TB-Days, so that PA does the
following:
• Shows positive TB-Days
• Ends the grace period for that particular XP7 disk array
7. So, if you want to install TB-Days on 12/09/2010 for a duration of five days, generate 110TB-Days of
Meter based Term license. Out of the 110TB-Days:
