Or use the command:
# vxdisk init disk_name
VxVM utilities will not tamper with any disks 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.
The conversion process involves many steps. Though there are tools to help you
with the conversion, some of these steps cannot be automated. You should be sure
to understand how the whole conversion process works, and what you will need
to do in the process before beginning a volume group conversion.
The tool used for conversion is vxvmconvert. This interactive, menu-driven
program walks you through many of the steps of the process of converting volume
groups for use by VxVM. Using vxvmconvert can reduce the downtime associated
with converting from LVM to VxVM. Without the vxvmconvert tool, the only
possible method of conversion would be to take full backups of user data, destroy
the existing LVM configuration leaving only raw disks, recreate the configuration
in VxVM, and then reload the user data.
The vxvmconvert process converts LVM volume groups to VxVM disk groups in
place. In reality, the utility changes disks within LVM volume groups to VxVM
disks by taking over the areas of the disks used for LVM configuration information,
and creating the equivalent VxVM volume configuration information. User data,
the portions of the disks used for file systems, databases and so on, are not affected
by the conversion.
The act of conversion changes the names by which your system refers to the
logical storage. For this reason, the conversion process is necessarily an off-line
one. There can be no application access to user data in the volume groups
