 volcopy_hfs(1M)					     volcopy_hfs(1M)




 NAME
      volcopy, labelit - copy an HFS file system with label checking

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

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

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

    Options
      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.
