Converting LVM to VxVM
Converting Unused LVM Physical Volumes to VxVM Disks
Chapter 2 25
lvmtab and the LVM headers indicate it is not a member of any volume
group. (That is, it has been pvcreated but not been an argument for
vgcreate or vgextend.)
After running pvcreate, then use pvremove to erase all vestiges of LVM
disk headers.
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 disks that are recognized as owned
by LVM (by virtue of the LVM disk headers). If you attempt to use
vxdisk init,orvxdiskadm on an LVM disk without using the pvremove
command first, the command will fail.
