/INIT_TSNS can only be specified for all storage areas

  Explanation:   RMU/REPAIR/INITIALIZE=TSNS  cannot  be  specified
  with  a  specific  list  of  storage  areas  since  TSNs must be
  initialized on pages in all areas of the database.

  User Action:  Respecify the command for all storage  areas  (the
  default).
