Thank you @Peasant for the reply. I wanted to provide an update...
The process was actually much easier than expected. We just needed to:
1. Snapshot the original LUN.
2. Create the same mount point on the new server.
3. Copy the /etc/fstab entry from original server and write it to the /etc/fstab on the new server.
4. Present the snapshot LUN to the new server.
5. Reboot the new server.
This allowed us to to see the original data as expected.
Thanks again for the help..

Hiya,
Is there a known method from converting LVM data to VxVM data..
ie we have a load of local and SAN (HPDM) mounts on RHEL 4u5/5u1 servers which are now required to be clustered with SFS (VxFS,VxVM,CFS,VCS etc)
I've come across the vxvmconvert, but thought that was HP-UX only?

endfsent
GETFSENT(3) Linux Programmer's Manual GETFSENT(3)
NAME
getfsent, getfsspec, getfsfile, setfsent, endfsent - handle fstab entries
SYNOPSIS
#include <fstab.h>
void endfsent(void);
struct fstab *getfsent(void);
struct fstab *getfsfile(const char *mount_point);
struct fstab *getfsspec(const char *special_file);
int setfsent(void);
DESCRIPTION
These functions read from the file /etc/fstab. The struct fstab is defined by
struct fstab {
char *fs_spec; /* block device name */
char *fs_file; /* mount point */
char *fs_vfstype; /* filesystem type */
char *fs_mntops; /* mount options */
const char *fs_type; /* rw/rq/ro/sw/xx option */
int fs_freq; /* dump frequency, in days */
int fs_passno; /* pass number on parallel dump */
};
Here the field fs_type contains (on a *BSD system) one of the five strings "rw", "rq", "ro", "sw", "xx" (read-write, read-write with quo-
tas, read-only, swap, ignore).
The function setfsent() opens the file when required and positions it at the first line.
The function getfsent() parses the next line from the file. (After opening it when required.)
The function endfsent() closes the file when required.
The function getfsspec() searches the file from the start and returns the first entry found for which the fs_spec field matches the spe-
cial_file argument.
The function getfsfile() searches the file from the start and returns the first entry found for which the fs_file field matches the
mount_point argument.
RETURN VALUE
Upon success, the functions getfsent(), getfsfile(), and getfsspec() return a pointer to a struct fstab, while setfsent() returns 1. Upon
failure or end-of-file, these functions return NULL and 0, respectively.
HISTORY
The getfsent() function appeared in 4.0BSD; the other four functions appeared in 4.3BSD.
CONFORMING TO
These functions are not in POSIX. Several operating systems have them, e.g., *BSD, SunOS, Digital Unix, AIX (which also has a getfstype()).
HP-UX has functions of the same names, that however use a struct checklist instead of a struct fstab, and calls these functions obsolete,
superseded by getmntent(3).
NOTES
These functions are not thread-safe.
Since Linux allows mounting a block special device in several places, and since several devices can have the same mount point, where the
last device with a given mount point is the interesting one, while getfsfile() and getfsspec() only return the first occurrence, these two
functions are not suitable for use under Linux.
