Two options:
1. use a command from the database edition that provides this sort of
mapping:
vxstorage_stats
Although this command was targeted at the database market, it works on
any file.
The requirements and such are in chapter ~8 of the DBED Administrator's
Guide. Man page below. Note that, at least in the past, the developers
stuck this and other commands in their own directory, rather than
provide links into /opt/VRTS/bin, so you may have to edit your PATH
variable.
2. use fsdb to get the block map of the file; use that to calculate the
offsets yourself and figure out the corresponding volume locations; use
those to figure out the subdisk locations.
Note that a file can have >1 extent, and an extent can span subdisks, so
a file can very possibly reside on multiple LUNs.

vxstorage_stats
NAME
vxstorage_stats - Veritas Storage Foundation for Databases file
statistics utility
SYNOPSIS
For Oracle: /opt/VRTSdbed/bin/vxstorage_stats [-m] [-s]
[-i interval -c count ] -f filename
For DB2:
/opt/VRTSdb2ed/bin/vxstorage_stats [-m] [-s]
[-i interval -c count ] -f filename
AVAILABILITY
This command is part of Veritas Storage Foundation for Databases.
To determine whether Veritas Storage Foundation for Oracle is installed
on a Solaris system, enter:
pkginfo -l VRTSdbed
To determine whether Veritas Storage Foundation for DB2 is installed on
a Solaris system, enter:
pkginfo -l VRTSdb2ed
DESCRIPTION
The vxstorage_stats command prints I/O mapping and statistics about one
or more Veritas File System files. The statistics are recorded only for
VxFS files and VxVM volumes. These statistics show I/O activity.
OPTIONS
The following options are supported:
-m
Displays the I/O stack mapping topology for the specified file.
-s
Displays the file statistics for the specified file.
-c count
Specifies the number of times to print statistics. -i interval is
required to use -c count.
-i interval
Specifies the interval frequency for printing updated I/O statistics. If
the -i interval option is supplied, statistics are prefaced with a time
stamp showing the current local time on the system. If -i interval and
-c count are not specified, the default is one count (that is,
statistics will be printed a single time). Note: I/O topology
information is printed first; subsequent refreshes display statistics
only.
-f filename
Specifies the file to print I/O mapping and statistics for.
NOTES
In vxstorage_stats command output, I/O topology information appears
first followed by summary statistics for each object. Summary statistics
are printed in single line output records, preceded by two header lines.
The output line consists of the following space-separated fields:
*file name
*number of read operations
*number of write operations
*number of blocks read
*number of blocks written
*average time spent on read operations in the interval
*average time spent on write operations in the interval
The vxstorage_stats command exits with a non-zero status if the
attempted operation fails. A non-zero exit code is returned for the
first condition that prevented execution of the utility.
EXAMPLES
Note that for Oracle, the command is located under /opt/VRTSdbed/bin.
For DB2, it is located under /opt/VRTSdb2ed/bin.

So the volume consists four disks (in fact LUNs) with vxfs on it. There
are many files on the filesystem.
Can I check somehow on which LUN(s) some particular files are placed ?
