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 displays 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.

  Certain metadata files are in fixed locations:

  ______________________________________________________
			   Page	  Cell	 Volume
  ______________________________________________________
  Bitfile metadata table   0	  0	 Every volume
  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.









EXAMPLES
  The following command will extract the contents of the log from the device
  /dev/rz23h and place it in a new file called log.

       # vfile 0 3 /dev/rz23h > log
