VERITAS Volume Manager 3.5 Migration Guide (September 2004)

Chapter 1

VxVM and LVM

Coexistence of VxVM and LVM Disks

Both LVM disks and VxVM disks can exist together on a system. The LVM disks are detected and displayed

as such by VxVM. LVM disks are not selected by VxVM for initialization, addition, or replacement.

Both LVM and VxVM utilities are aware of the other volume manager, and will not overwrite disks that are

being managed by the other volume manager. The administrative utilities (SAM and vmsa) recognize and

identify all disks on the system (see Chapter 4, “SAM and the VEA,” on page 53, for details).

The vxvmconvert command is provided to enable LVM disks to be converted to a VxVM disk format without

losing any data. For more information, see Chapter 2, “Converting LVM to VxVM,” on page 9.
