Veritas Volume Manager 5.0.1 Migration Guide, HP-UX 11i v3, First Edition, November 2009

If pvdisplay finds no valid group information associated with the disk, you can
overwrite the LVM headers using pvcreate:
# pvcreate disk_name
Warning: If disk_name is an alternate path to a disk that does not appear in the
lvmtab file for this system, or is a disk that is in use on another system, but not
imported onto this system, then do not pvcreate -f the disk. Doing so will destroy
the LVM headers. You can use pvcreate without the -f option safely, as it will
only succeed if the disk is not listed in the /etc/lvmtab file, and if the LVM headers
indicate that it is not a member of any volume group. (That is, pvcreate has been
run on the disk, but neither vgcreate nor vgextend have.)
Initializing disks for VxVM use
To initialize the disk for VxVM use, use the vxdiskadm command, selecting the
option:
1) Add or initialize one or more disks
Or use the command:
# vxdisk init disk_name
VxVM utilities will not tamper with anydisks that are recognized as owned by
LVM (by virtue of the LVM disk headers). If you attempt to use vxdisk init, or
vxdiskadm on an LVM disk without using the pvremove command first, the
command fails.
Note: The above behavior is displayed on both LVM version 1 and version 2 volume
groups.
Converting LVM volume groups to VxVM disk groups
This section outlines the process for converting LVM volume groups to VxVM
disk groups.
Note: Symantec recommends that you read through this section carefully before
you begin any volume group conversion.
