This field displays the total number of activated Reserve CoD processors on your managed system. Activated Reserve CoD processors are placed in the default shared processor pool, where they are used as needed by uncapped partitions. The Reserve CoD processors are used only when the capacity of the non-Reserve CoD processors in the default shared processor pool is no longer sufficient to support the workload. When a Reserve CoD processor is used, a reserve processor day is charged against the Reserve CoD prepaid number of days. You pay only for the number of processor days that the processors are actually used. The processors can remain active until the number of days you have paid for has been used.
