 NAME    [Toc]    [Back]
      volcopy_hfs: volcopy, labelit - copy an HFS file system with label
      checking

 SYNOPSIS    [Toc]    [Back]
      /usr/sbin/volcopy [options] fsname special1 volname1 special2
           volname2

      /usr/sbin/labelit [options] special [fsname volume [-n]]

 DESCRIPTION    [Toc]    [Back]
      The volcopy command makes a literal copy of an HFS file system using a
      block size matched to the device.

    Options    [Toc]    [Back]
      volcopy recognizes the following options:

           -F hfs         Specifies the HFS file system type.

           -a             Invoke a verification sequence requiring a
                          positive operator response instead of the standard
                          delay before the copy is made.

           -s             (default) Invoke the DEL-if-wrong verification
                          sequence.

           -y             Assume a yes response to all questions

           -V             Echo the completed command line, but perform no
                          other actions.  The command line is generated by
                          incorporating the user-specified options and
                          arguments with other information derived from
                          /etc/fstab.  This option allows the user to verify
                          the command line.

      Other options are used with 9-track magnetic tapes:

           -bpi density   Bits per inch.

           -feet size     Size of reel in feet.

           -reel num      Beginning reel number for a restarted copy.

           -buf           Use double buffered I/O.

      The volcopy command requests length and density information if they
      are not given on the command line and they are not recorded on an
      input tape label.  If the file system is too large to fit on one reel,
      the volcopy command prompts for additional reels.  Labels of all reels
      are checked.  Tapes can be mounted alternately on two or more drives.
      If the volcopy command is interrupted, it asks if the user wants to

      quit or wants to escape to the command interpreter.  In the latter
      case, other operations (such as executing the labelit command) can be
      performed before returning to the volcopy command by exiting the
      command interpreter.

      fsname    The file system name on the device (e.g., root) being
                copied.

      special   The physical disk section or tape (e.g., /dev/rdsk/1s3 or
                /dev/rmt/c0t0d0BEST).

      volname   The physical volume name; it should match the external
                sticker.  Such label names are limited to six or fewer
                characters.  The argument volname can be - to use the
                existing volume name.

      special1  The device from which the copy of the file system is being
                extracted.

      volname1  The volume from which the copy of the file system is being
                extracted.

      special2  The target device.

      volname2  The target volume.

      The labelit command can be used to provide initial labels for
      unmounted disk or tape file systems.  With the optional arguments
      omitted, the labelit command prints current label values.  The -n
      option provides for initial labeling of new tapes only (this destroys
      previous contents).  The -F and -V options can be specified for the
      labelit command.  The behavior of the -F and -V options is similar to
      their behavior in the volcopy command.
