The following figure depicts setting the subscription limit of pool capacity.

Monitoring total THP-VOL subscription for a pool

You can configure the Subscription Limit of total THP-VOL capacity to pool capacity. This prevents
a new THP-VOL capacity that exceeds the configured subscription limit from being allocated and
is associated to the pool. If you specify more than 100% as the Subscription Limit or the subscription
limit is not set, you must monitor the free capacity of the pool because it is possible that writes to
the THP-VOLs may exceed pool capacity.. For details about the Subscription Limit, see

(page 288)

.

The used value displayed on the cell for Current in the Subscription (%) is truncated after the decimal
point of the calculated value. Therefore, the actual percentage of THP-VOL assigned to the pool
may be larger than the value displayed on the window. If you create a new THP-VOL of the same
size as the existing THP-VOL, the larger size of capacity which is displayed on the Current cell is
necessary.

For example, if 3 GB V-VOL is related to an 11.89 GB pool, the capacity (%) is calculated as
follows:

(3ч11.89)Ч100 = 25.23....(%)

In this case, 25 (%) is displayed on the cell for Current in the Subscription (%). If you create a new
V-VOL of the same size as the existing V-VOL, 26 (%) or more remaining capacity is necessary.
