     NAME
          autorecovery - file-system repair procedure

     DESCRIPTION
          Autorecovery refers to the facilities that check and  repair
          A/UX  file systems.  It includes a variety of tools, some of
          which run under the A/UX Startup application,  and  some  of
          which run under A/UX.  Autorecovery depends on the existence
          of one or more parallel file systems  containing  copies  of
          critical system files.  These file systems are maintained on
          an incremental basis using the appropriate autorecovery pro-
          grams.   The  actual  checking and correction tasks are per-
          formed within the Macintosh portion of the boot sequence and
          are invoked manually as desired from within the A/UX Startup
          application.  The checking and correction  portions  of  au-
          torecovery  can  also run automatically upon booting, if the
          environment has been set up properly.

          autorecovery is also the name of an A/UX StartupShell  vari-
          able  that  contains  the autorecovery command string.  This
          command string is  executed  whenever  you  boot  A/UX  (see
          StartupShell(8)).  The command string has been initially set
          to echo no autorecovery as an indication  that  autorecovery
          is not being run.

          To request  autorecovery  manually,  run  the  esch  command
          directly  from  the  StartupShell.  An alternative is to set
          autorecovery so that the desired form of the esch command is
          run automatically upon booting.

          The A/UX programs that help support the  proper  functioning
          of autorecovery are those listed next with the ``1M'' desig-
          nation.
