Hi,
That script does provide some very useful information. Thank you very much for the link.
I am not proficient at scripting by any stretch of the imagination but the comments on what the lines of the script do are very helpful.
I am not sure if the results provide all the information with respect as to parent disks (not sure how to describe this but will give it a whirl)
The environment uses vCloud Director and copies of entire environments of VM's are stored in a catalog. We are using linked clones.
Information as to how current VM's disks are linked to older VM directories would be useful although I do not know if that is achievable - although I will continue to investigate.
Thanks for your time and response.
Henry
