Virtual objects

VxVM uses multiple virtualization layers to provide distinct functionality and reduce physical limitations.

Virtual objects in VxVM include the following:

The connection between physical objects and VxVM objects is made when you place a physical disk under VxVM control.

After installing VxVM on a host system, you must bring the contents of physical disks under VxVM control by collecting the VM disks into disk groups and allocating the disk group space to create logical volumes.

To bring the physical disk under VxVM control, the disk must not be under LVM control.

For more information on how LVM and VM disks co-exist or how to convert LVM disks to VM disks, see the Veritas Storage Foundation Migration Guide.

Bringing the contents of physical disks under VxVM control is accomplished only if VxVM takes control of the physical disks and the disk is not under control of another storage manager such as LVM.

VxVM creates virtual objects and makes logical connections between the objects. The virtual objects are then used by VxVM to do storage management tasks.

The vxprint command displays detailed information about the VxVM objects that exist on a system.

See the vxprint(1M) manual page.
