NAME

vbmtchain - displays mcells that describe metadata for a file  

SYNOPSIS

/sbin/advfs/vbmtchain BMT_page cell special [special 2...]


 

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. Specifies the other volumes in this domain that may be accessed to follow the file's mcell chain.
 

DESCRIPTION

The vbmtchain utility displays metadata for a file. The file is described 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:


PageCellVolume

Bitfile metadata table00every volume
Storage bitmap01every volume
Root tag directory02volume with log
Transaction log file03volume 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 directory or a data file.
 

RESTRICTIONS

You must have root user privileges to access this command.
