Migrating from LVM to VxVM Data Storage
Appendix G 511
G Migrating from LVM to VxVM
Data Storage
This appendix describes how to migrate LVM volume groups to VxVM
disk groups for use with the Veritas Volume Manager (VxVM), or with
the Cluster Volume Manager (CVM) on systems that support it. Topics
are as follows:
•Loading VxVM
• Migrating Volume Groups
• Customizing Packages for VxVM
• Customizing Packages for CVM
• Removing LVM Volume Groups
The emphasis is on the steps you must take to manage the cluster and
packages during migration; detailed instructions for configuring VxVM
disk groups are at http://docs.hp.com in the Veritas Volume Manager
Administrator’s Guide and the Veritas Volume Manager Migration Guide
for your VxVM version. Refer to Chapter 5 of the present manual for
information on creating basic storage for a new system starting with
fresh disks.
The procedures described below can be carried out while the cluster is
running, but any package that uses a volume group that is being
migrated must be halted. For disk groups that will be used with the
Cluster Volume Manager (CVM), on systems that support it, an
additional set of steps is provided.
