Convert a volume group
To do the actual conversion of LVM volume groups to VxVM disk groups, choose option 2 of the vxconvert utility.
vxconvert will prompt for a name for the VxVM disk group that will be created to replace the LVM volume group you are converting. This is the only object naming that is done through vxconvert.
VxVM volume names may need modified.
See Tailor your VxVM configuration.
The volume groups selected for conversion are analyzed to ensure that conversion is possible.
See Analyze an LVM volume group to see if conversion is possible.
After a successful analysis phase, vxconvert will ask you to commit to the change or abort the conversion. When you select to commit to conversion, the new VxVM metadata is written.
Note:
It is good practice to convert one volume group at a time to avoid errors during conversion.
Examples with details of the conversion process are available.
