  1. Identify the data you want

    1. SFC, 6 parameters
    2. Time: 00, March 2017
    3. all steps (0/to/90/by/1, 93/to/144/by/3 and 150/to/360/by/6)
    4. all numbers (1/to/50)

  2. Use MARS list to find out the size

    LIST,
    CLASS      = OD,
    TYPE       = PF,
    STREAM     = ENFO,
    EXPVER     = 0001,
    LEVTYPE    = SFC,
    PARAM      = 134.128/151.128/165.128/166.128/246.228/247.228,
    DATE       = 20170301/to/20170331,
    TIME       = 0000,
    STEP       = 0/1/2/3/4/5/6/7/8/9/10/11/12/13/14/15/16/17/18/19/20/21/22/23/24/25/26/27/28/29/30/31/32/33/34/35/36/37/38/39/40/41/42/43/44/45/46/47/48/49/50/51/52/53/54/55/56/57/58/59/60/61/62/63/64/65/66/67/68/69/70/71/72/73/74/75/76/77/78/79/80/81/82/83/84/85/86/87/88/89/90/93/96/99/102/105/108/111/114/117/120/123/126/129/132/135/138/141/144/150/156/162/168/174/180/186/192/198/204/210/216/222/228/234/240/246/252/258/264/270/276/282/288/294/300/306/312/318/324/330/336/342/348/354/360,
    NUMBER     = 1/to/50,
    OUTPUT     = cost

    When we run the list action this is the output:

    size=4484574297000; # 4.48 TB
number_of_fields=1348500;
online_size=799241928660;
off_line_size=3685332368340;
number_of_tape_files=93;
number_of_disk_files=281;
number_of_online_fields=240330;
number_of_offline_fields=1108170;
number_of_tapes=32;

    The data is too large: 4.48 TB and split across 32 tapes.

  3. Use the MARS catalogue to know the data distribution in files and tapes
