LVM-viewer is a tool made up for viewing as well as for managing it in the Logical Volumes. It permits you to visualize all your volume groups, physical volumes, and the logical volumes. Logical Volume Management is been supported by the Linux kernel edition 2.2 (+patch) and 2.3.99, and HP/UX. This type of tool works well with the HP-UX, but it does not have any kind of support for the RedHat Linux, as RedHat does not include a pvcreate, lvcreate, vgdisplay, or any other similar commands in it.
