 volcopy_vxfs(1M)					    volcopy_vxfs(1M)




 NAME
      volcopy, labelit - copy a VxFS file system with label checking

 SYNOPSIS
      /usr/sbin/volcopy [-F vxfs] [-V] [-a] [-s] [-y] fsname special1
	   volname1 special2 volname2

      /usr/sbin/labelit [-F vxfs] [-V] [-n] special [fsname volume]

 DESCRIPTION
      volcopy makes a literal copy of a VxFS file system using a block size
      matched to the device.

    Options
      volcopy recognizes the following options and command-line arguments:

	   -F vxfs	  Specify the file-system type (vxfs).

	   -V		  Validate the command line options, but do not
			  execute the command. If the options specified are
			  valid, -V echoes the complete command line.  If
			  the options specified are not valid, -V prints an
			  error message.

	   -a		  Normally, before copying the file system, volcopy
			  delays so that the user can interrupt the copying
			  if needed. This option invokes a verification
			  sequence requiring a positive operator response
			  instead of the standard delay.

	   -s		  (default) Before copying the file system, prints a
			  message and allows the user to interrupt the copy
			  if needed.

	   -y		  Assume a yes response to all questions

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

      interrupted, it asks if the user wants to quit or to escape to the
      command interpreter.  In the later case, other operations (such as
      labelit) can be performed before returning to volcopy by exiting the
      command interpreter.

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

      special should be the physical disk section or tape (e.g.,
      /dev/rdsk/c0t4d0s0 or /dev/rmt/0mb).

      volname is 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.

      The arguments special1 and volname1 are the device and volume,
      respectively, from which the copy of the file system is being
      extracted.  The arguments special2 and volname2 are the target device
      and volume, respectively.

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

 WARNINGS
      volcopy and labelit will be unsupported in a future release.  Use
      vxdump(1M) and vxrestore(1M) for backup and restore, or use an
      application-specific utility.  Use dd(1) to make a literal copy of the
      filesystem.
