    Status code 86 indicate a "media position error".

    See :

    I often see media position errors on worn-out LTO drives or drives that badly need a cleaning tape. Another reason for status code 86 is a previous status code 84.

    My advise: use cleaning tape, suspend media with status code 86 (use the GUI)

A log of design has been put into the LTO series to reduce the need to cleaning tapes (e.g internal cleaning brush). However our local StorageTek/SUN/Oracle rep. recommend to use a cleaning tape once a month - and we use our drives at least 14 hour every day.
