Adding a Disk to Volume Manager
You must place a disk under Volume Manager control, or add it to a disk
group, before you can use the disk space for volumes. If the disk was

preserve existing data on the disk while still letting the Volume Manager
take control of the disk. If the user wants to bring all the non LVM disks
under control, they are considered as fresh disks. LVM volume groups

not under Volume Manager control, but no data is required to be
preserved, it should be initialized.
NOTE See the VERITAS Volume Manager Migration Guide for more
