Consider that the usable capacity exceeds the 50TB Permanent licensed capacity by 10TB in the
second half of 12/03/2010. As a result, P9000 Performance Advisor updates the above listed fields
after 1:00 PM only on the next day (12/04/2010), though the 10TB-Days are already used from
the 90TB-Days on 12/03/2010.
After the installed TB-Days are completely used and one of the following actions is not completed,
P9000 Performance Advisor enters 60 days grace period for that particular P9000 disk array:
• A Permanent or appropriate TB-Days of Meter based Term license installed to monitor the additional
usable capacity.
• The additional usable capacity reduced to match the Permanent licensed capacity.
In addition, P9000 Performance Advisor 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 usable capacity that needs to be monitored. After 60 days, a capacity
violation is reported and P9000 Performance Advisor 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 usable capacity. As a result, P9000
Performance Advisor 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 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:
