Script for virtual disk mapping information

[linuxsysadm]

Hello Everyone,

In order to get mapping of virtual disks allocated to a virtual machine and disks visible in the Linux OS, I’ve written attached script.

Please feel free to use it as per your requirement and cross check results before you start using it for the production environment, also please report any discrepancies/issues, will try and address those if possible.
