Conversion Process Summary

Several steps are used to convert LVM volume groups to VxVM disk groups. Most of these steps can be done with the vxvmconvert utility. All the steps are not compulsory, and some may have to be followed only if there are problems during conversion. Some of them (e.g. backing up user data) are left to you to accomplish through your regular administrative processes.

The steps in the conversion process are:

1. Identifying LVM volume groups for conversion.
2. Analyzing an LVM group to see if conversion is possible.
3. Taking actions to make conversion possible if analysis fails.
4. Backing up your LVM configuration and user data.
5. Planning for new VxVM logical volume names.
6. Stopping application access to volumes in the volume group to be converted.
7. Converting a volume group.
8. Taking actions if conversion fails.
9. Implementing changes for new VxVM logical volume names
10. Restarting applications on the new VxVM volumes.
11. Tailoring your VxVM configuration.

These steps are described in detail in later sections of this chapter. Annotated examples on how to use vxvmconvert are shown in Examples. For information on restoring back to your original LVM configuration refer to Restoring the LVM Volume Group Configuration.
