Assume the following values:

• blk_size is 3,600
• x2 is 3 (three data sets per volume)
• x3 is 500 (500 volumes are mounted each day)
• x4 is 500 (500 volumes become scratch each day)
• x5 is 250 (250 volumes change location every day)
• x6 is 2 (the Trace file should retain data for two days)

The following is the calculation:

1. x1 is (3,600 - 10) / (660+58) = 5
2. tf_num_rcds is
   ((6*3 + 6) * 500 + 2 * 500 * (3 + 1) + 2 * 250) * 2 = 33,000

tf_num_blks = (33,000 / 5) + 10 = 6610
