NAME
vfile - displays the contents of a file from an unmounted domain
SYNOPSIS
/sbin/advfs/vfile BMT_page cell special [special 2 ...]
Specifies the page within the bitfile metadata table (BMT) of the vol-
ume 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 vfile utility outputs the contents of a file from an unmounted do-
main. 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:
tab(@); lfHB lfHB lfHB lfHB l l l l. _

vice /dev/rr23h and place it in a new file called log.
