Summary:A technique facilitates hanging of a liner in a borehole. According to the technique, a liner hanger and a liner may be deployed downhole into a borehole. A wellbore anchoring device of the liner hanger is initially actuated to engage a surrounding surface and to resist downward movement of the liner. Additionally, a hold down anchor is subsequently actuated to resist upward movement of the liner. The hold down anchor may be released via mechanical manipulation of the liner hanger.
