Veritas Volume Manager 5.0 Migration Guide, HP-UX 11i v3, First Edition, May 2008

19Converting LVM to VxVM
Converting LVM volume groups to VxVM disk groups
■ A volume group containing the /usr file system.
For this release, a volume group containing the /usr file system cannot be
converted because vxvmconvert needs access to files in /usr.
■ Volume groups with any dump or primary swap volumes.
vxvmconvert will not convert any volume group with dump or primary swap
volumes. These are volumes known to the boot process. However, swap
volumes on volumes other than the root volume can be converted (as long
as this volume is not in the same volume group as the root volume).
■ Volume group disks used in MC/ServiceGuard clusters.
The conversion process does not support conversion of any volume group
that is marked as a member of a MC/ServiceGuard or OPS Edition high
availability cluster. The volume group must be deactivated and removed
from membership in the high availability cluster before it can be converted.
■ Volume groups used for cluster lock disks.
The conversion process does not support conversion of a volume group that
contains a disk that is being used for a cluster lock disk for an
MC/ServiceGuard cluster.
■ Volume groups with any disks that have bad blocks in the bad block
directory.
Unlike LVM, VxVM does not support bad block revectoring at the physical
volume level. If there appear to be any valid bad blocks in the bad block
directory of any disk used in an LVM volume group, the group cannot be
converted. See Appendix A, Conversion Error Messages, for actions to take
in this situation.
■ Volume groups with mirrored volumes.
A conversion fails if the LVM volume group being converted has mirrored
volumes, but the system does not have a valid license installed that enables
mirroring for VxVM.
The analyze option in vxvmconvert, which is described in later sections, aids you
in identifying which volume groups can be converted.
