Migrating from RHEL LVM to VxVM

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?

Many thanks...
