NAME

       vtagpg - displays a formatted page of the tag directory

SYNOPSIS

       /sbin/advfs/vtagpg special [page_LBN]

OPERANDS

       Specifies  the  volume  on  which  the  tag directory is located.  Specifies the logical block number (LBN) of the page to be examined; the
       default is zero.

DESCRIPTION

       The vtagpg utility translates a 16-block part of a volume of a mounted or unmounted file system and formats it as  a  tag  directory.   Use
       this utility with other file utilities to locate file-structure anomalies for debugging.

       If  the volume is mounted, use the showfile -x command to get the extent map before calling the vtagpg command. If the volume is unmounted,
       call the vbmtchain command to identify the extent information.

       Run the vtagpg utility to obtain the root tag directory first because it has entries for each fileset in the domain. Then, run the  utility
       again to view the tag directory for the fileset under investigation.  This tag information points to the fileset metadata.

       The vtagpg utility displays tag entries that map file inode number to primary mcell location.

RESTRICTIONS

       You must be the root user to use this command.

EXAMPLES

       The following example displays the root tag directory located on volume dsk3h with LBN 96: # vtagpg /dev/rdisk/dsk3h 96

NAME

       vbmtchain - Displays the contents of a reserved file from an unmounted domain.

SYNOPSIS

       /sbin/advfs/vbmtchain BMT_page cell special

OPERANDS

       Specifies  the  page  within  the bitfile metadata table (BMT) of the volume that contains the file's mcell.  Specifies the cell of the BMT
       page that contains the file's mcell.  Specifies the volume on which the file's primary mcell is located.

DESCRIPTION

       The vbmtchain utility displays the contents of a reserved file from an unmounted domain. The file is described by the location of its  pri-
       mary  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
       -------------------------------------------------------

       The  vbmtchain utility displays the attributes of the file, including the time stamp, the extent map, and whether the file is a user direc-
       tory or a data file.

RESTRICTIONS

       You must have root user privileges to access this command.
