vfile(8)
NAME
  vfile - saves the contents of a reserved file from an unmounted domain.

SYNOPSIS
  /sbin/advfs/vfile BMT_page cell special

OPERANDS
  BMT_page
      Specifies the page within the bitfile metadata table (BMT) of the
      volume that contains the file's mcell.

  cell
      Specifies the cell of the BMT page that contains the file's mcell.

  special
      Specifies the volume on which the file's primary mcell is located.

DESCRIPTION
  The vfile utility outputs the contents of a reserved file from an unmounted
  domain. The file is identified by the location of its primary mcell. Each
  mcell location is composed of three parts: volume, page within the BMT file
  located on that volume, and cell within the BMT page.

  The primary mcell for the root tag directory is found in the BMT of the
  volume containing the log. To find this volume for a domain, use the
  showfdmn or the advscan command. The volume marked "L" contains the log.

  This utility may be run for file domains prior to Version 5.0 or for
  Version 5 file domains specifically designated as having the older file
  format.  (File domain structure has changed in Version 5. Earlier file
  domains carry a domain version number (DVN) of 3 while Version 5.0 and
  later file domains have a DVN of 4.) Use the showfdmn command to obtain the
  correct version number of your system. For DVN of 4 and greater, use the
  nvbmtpg --d commmand to obtain file contents from unmounted domains.

  Certain metadata files are in fixed locations:

  ________________________________________________________
			   Page	  Cell	 Volume
  ________________________________________________________
  Bitfile metadata table   0	  0

					 every volume,
					 version 3 domains
			   0	  4

					 every volume,
					 version 4 domains
  Storage bitmap	   0	  1	 every volume
  Root tag directory	   0	  2	 volume with log
  Transaction log file	   0	  3	 volume with log
  ________________________________________________________








RESTRICTIONS
  You must be the root user to use this command.

  This utility may be used on DVN of 3 domains only.

EXAMPLES
  The following command will extract the contents of the transaction log from
  the device /dev/rdisk/dsk23h and place it in a new file called log.

       # vfile 0 3 /dev/rdisk/dsk23h > log
