Veritas Volume Manager (VxVM) provides the vxvmconvert utility for converting Logical Volume Manager (LVM) volume groups and the objects that they contain to the equivalent VxVM disk groups and objects. Conversion of LVM2 volume groups is supported provided that the version of LVM2 is 2.00.33 or later.
Disks on your system that are managed by LVM can be of two types:
Unused disks or disk partitions, which contain no user data, and are not used by any volume group, but which have LVM disk headers written by pvcreate.
LVM disks or disk partitions in volume groups, and which contain logical volumes and volume groups.
A converted VxVM disk group can also be reverted to an LVM volume group.
See the vxvmconvert(1M) manual page.
