For data items in the more important storage class 2, the system can make 6 reclaims for resources from storage class 1. With each reclaim from the storage class, the system subtracts from the counter (6 in this example) until the value equals zero. Then the system reads the vector value for the next storage class (storage class 2). For data items in storage class 2, the system can make 1 reclaim to satisfy requests. At this point, the system has made one pass through the vector. The system subtracts 1 from the repeat counter of 2, the original values in the vector are reset (6 for storage class 1 and 1 for storage class 2), and the system starts the second pass through the vector. When the repeat counter equals 0, the vector is deactivated and the system default for reclaim is in effect.
