# Data collected for Veritas Volume Manager on Linux

Discovery collects disk and volume information for Veritas Volume Manager \(VxVM\) on Linux hosts and maps file systems mounted on Veritas volumes to the upstream storage provider.

**Note:** Ensure that VxVM is correctly installed and configured. If you are using 3rd party drivers, you must configure sudo permission for `vxdmpadm`.

</table>## Displaying data

VxVM Discovery maps file systems to the disks that supply storage. By default this is the only information displayed in the UI. The file system to disk relationship is shown as an upstream **Stored on** relationship on the File System form. To see the remainder of the information that Discovery captures for VxVM, you must add the appropriate related list to the Linux Server form. The available lists are:

-   Veritas Disk Group
-   Veritas Disk
-   Veritas Plex
-   Veritas Subdisk \(Computer\)
-   Veritas Subdisk \(Storage\)
-   Veritas Volume
