/sbin/advfs/vbmtpg special [page_LBN]

page; the default is 32 which is page zero of the bitfile metadata table (BMT).
The vbmtpg utility displays a complete, formatted page of the BMT for a mounted or unmounted domain. This is useful for debugging when there has been some seemingly random file corruption.
Note that the
command displays all the
mcells associated with a given file whereas the
command displays a page of information. This page may contain information
for more than one file and may not provide complete information on any file.
You must have root user privileges to access this command.
