vtagpg - displays a formatted page of the tag directory
/sbin/advfs/vtagpg special [page_LBN]
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.
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.
utility displays tag entries that map
file inode number to primary mcell location.
You must be the root user to use this command.
The following example displays the root tag directory located on volume rz3h with LBN 96: # vtagpg /dev/rrz3h 96
