special 2...

DESCRIPTION
The vfile utility outputs the contents of a file from an unmounted domain.
The file is identified 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:
______________________________________________________
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
______________________________________________________
RESTRICTIONS
You must have root user privileges to access this command.
EXAMPLES
The following command will extract the contents of the log from the device
/dev/rr23h and place it in a new file called log.
# vfile 0 3 /dev/rr23h > log
