Coexistence of VxVM and LVM Disks
Chapter 122
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 Storage
Administrator, for details).
The vxvmconvert command enables LVM disks to be converted to a
VxVM disk format without losing any data. For more information, see
Chapter 2, Converting LVM to VxVM,.
