volcopy

volcopy(1M)															       volcopy(1M)

NAME

       volcopy, labelit - copy a file system with label checking

SYNOPSIS

       [options] fsname special1 volname1 special2 volname2

       [options] special [fsname volume

DESCRIPTION

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

   Options
       recognizes the following options:

	      Specify the file system type on which to operate (see
			     fstyp(1M)	and  fs_wrapper(5)).   If  this  option  is not included on the command line, then the file system type is
			     determined from the file by matching special with an entry in that file.  If there is no entry in then the file  sys-
			     tem type is determined from the file

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

	      Specify options specific to the file system type.
			     specific_options is a list of suboptions and/or keyword/attribute pairs intended for an FStype-specific module of the
			     command.  See the file system specific manual entries for a description of the specific_options that  are	supported,
			     if any.

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

	      Assume a	     response to all questions

	      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 This option allows the user to verify the command line.

       Other options are used with 9-track magnetic tapes:

	      Bits per inch.

	      Size of reel in feet.

	      Beginning reel number for a restarted copy.

	      Use double buffered I/O.

       The 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 command prompts for additional reels.  Labels of all reels are checked.
       Tapes can be mounted alternately on two or more drives.	If the 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 command) can be performed before returning
       to the command by exiting the command interpreter.

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

       special	 The physical disk section or tape (e.g., or

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

FILES

       File that specifies the default file system type.
       Static information about the file systems.
