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
