The PARAMETERS DISABLE CHECKS command enables you to override
    minimum and maximum values established for system parameters.
    SYSMAN does parameter checks by default. If you attempt to
    set parameter values outside the allowable limits when checks
    are enabled, the operating system issues an error message. By
    disabling checks you can set parameter values regardless of the
    minimum and maximum limits.

                                   NOTE

       Range checks are enabled by default because HP suggests that
       systems operate within these minimum and maximum values.
       Setting parameters outside these limits can result in system
       failures or hangs.
