Hi bernard666 ,
Thanks for reporting this issue. We are working on this issue.
We trying to reproduce the issue in-house with our setup.
What we have observed was all the RDM ( added in passthrough mode ) were partitioned into legacy MBR, with the partition format as GPT for the RDM before adding it to the VM. This happened with all the 3 RDM's.
Then we added the RDM's to the VM and checked the Output from UI as well backend.
As for now we are not able to reproduce the issue.
We are trying out with other options as well.
I had some queries, It would be great if you can help us in understanding the issue.
-> Which ESX release was used? Any update version?
-> What are the exact reproduction steps.
-> Was RAW Disk Partition done inside the VM(using disk management tool) or In ESX( using partedUtil) or both?
-> if Partition was done in ESX, then When was the partition done before adding the RDM disk or after adding
-> If you can provide some error messages, or Screenshots then that would be helpful as well
We will revert back once we get any results.
