About LVM to VxVM conversion

This chapter explains how to convert your LVM configuration to a VxVM

configuration.

The basic tools for conversion are the VxVM commands, vxvmconvert and

vxdiskadm, and the LVM administrative utilities such as pvremove and

vgcfgbackup. The discussion here details how to use these tools and gives some

insights into how these tools work.

Note: This release only supports the conversion of LVM version 1 volume groups

to VxVM. It does not support the conversion of LVM version 2 volume groups.

The disks on your system that are managed by LVM can be of two types: LVM

disks in volume groups, and unused disks.
