In addition, PA reduces the installed TB-Days every day after 1:00 PM till one of the above-mentioned
actions is performed. The reduction (negative count) of TB-Days is proportional to the additional physical
usable capacity that needs to be monitored. After 60 days, a capacity violation is reported and PA stops
monitoring that disk array.
Consider that the 90TB-Days are completely used in the first half of 12/11/2010 and appropriate TB-Days
are not yet installed to monitor the 10TB additional physical usable capacity. As a result, PA does the
following:
1. Enters 60 days grace period at 1:00 PM on the same day and 0TB-Days are available.
2. Begins reduction (negative count) of installed TB-Days.
The reduction continues for the next 59 days and the every day reduction is proportional to the 10TB
additional physical usable capacity that needs to be monitored. After 60 days, a capacity violation is
reported.
After 1:00 PM on 12/11/2010 (Day 1 of grace period), the following fields on the License screen - License
Status section display:
Screen elements - License Status
section
License Capacity
Term (Days)
License Status
End Date
The License Capacity continues to display every day reduction in TB-Days till 02/08/2011 (60th day).
The remaining fields listed in the above table remain the same.
• On 12/12/2010, the License Capacity shows 50TB, –10TB-Days
• On 12/13/2010, the License Capacity shows 50TB, –20TB-Days
• On 02/08/2011, the License Capacity shows 50TB, –590TB-Days
NOTE: If 90TB-Days are completely used in the second half of 12/11/2010, PA enters 60 days
grace period on the same day but updates the License screen - License Status section only after
1:00 PM on 12/12/2010. In this case, the License Capacity shows 50TB, –10TB-Days on
12/12/2010.
For information on calculating the appropriate TB-Days to end the grace period and also read additional
scenarios, see Exceeding meter-based term licensed capacity and grace period on page 56.
A Meter based Term license least count is 1TB-Days. By default, fractions of a TB of physical usable
capacity is considered as 1TB and fractions of a day is considered as one day.
