This field displays the amount of On/Off Capacity on Demand (CoD) memory resources that has been used outside of any On/Off CoD request since the last report. This amount is expressed in memory unit days.
For example, you request two On/Off CoD memory units for two days and assign both memory units to logical partitions. If the memory units are still assigned to logical partitions at the end of the two days, the amount in this field increases by two for each additional day that the memory units remain assigned to logical partitions. You will be billed for using these memory units for as long as they remain assigned to logical partitions. To avoid being billed for these memory units, you must remove the memory units from the logical partitions before the end of the On/Off request.
