Migrating from LVM to VxVM Data Storage
Appendix G 457
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). Topics are as follows:
• Loading VxVM
• Migrating Volume Groups
• Customizing Packages for VxVM
• Customizing Packages for CVM 3.5 and 4.1
• 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 given in the VERITAS Volume Manager Administrator’s
Guide and the VERITAS Volume Manager Migration Guide at
http://docs.hp.com/. Refer to Chapter 5 if you wish to create 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), an additional set of steps is provided.
