Spams
    Nospams

    Specifies whether to enable the creation of space area management
    (SPAM) pages or to disable the creation of SPAM pages (Nospams)
    for specified storage areas when converting read/write storage
    areas to write-once storage areas or vice versa. This qualifier
    is not permitted with a storage area that has a uniform page
    format.

    When SPAM pages are disabled in a read/write storage area, the
    SPAM pages are initialized, but they are not updated.

    The Spams qualifier is a positional qualifier.
