Usage notes

When using the TAPESUM command, consider the following:

  1. The following information is reported for each pool by media type:
    Scr Vols
    The number of eligible scratch volumes.
    Free Vols
    The number of volumes with a use-status of FREE.
    Used Vols
    The number of volumes with a use-status of USED.
    7 Day Exp
    The number of volumes due to expire within seven days.
    Total Vols
    The total number of volumes in the pool.

    The totals for each pool value above are summarized for each media type. The totals for each media type are summarized for the entire catalog.

    Volumes that are FREE are not included in the scratch count if they are on hold, external, or have a DSE action pending.
    Note: The FREE column in the POOLQRY command output is equivalent to the Scr Vols column in the TAPESUM output.

    Volumes that are USED, with an expiration data less than the seven-day range, are not included in the expiration total if they are on hold, external, or have a DSE action pending. The range includes today plus the next seven days.

    Volumes that are category managed with an Expiration Hold (i.e. volumes with SSTAT XH), which would otherwise expire, will be added to the seven-day expiration total if the expire hold period ends within the seven-day window.

  2. Depending on the size of the catalog and other performance factors, the TAPESUM processing can run for an extended time. Other Tape Manager functions will not be performed when the processing is occurring, so care should be taken when using this command. A review of the Tape Manager log can provide some information about the typical length of TAPESUM processing, but that time might not be representative of the process duration at other times of the day.
