  • 1.  ESXi 8 RDM not working

    Posted Dec 03, 2022 01:29 AM

    When I add rdm disk to vm on esxi8, it doesn't work properly.

    I make RDM vmdk disk by command below...

    vmkfstools -z /vmfs/devices/disks/vml.01000000004b314b3532544d44202020202020202020202020484753542048 /vmfs/volumes/SSD1TB01/RDM/rdm-disk3t.vmdk

    And I attached the device by adding an existing disk, but it is not attached normally as shown below.

    There is a workaround using vmware PowerCLI but I gives me “not supported with this license” type of error. I think it is not supported with free license. I have workstation pro though i can try with that. Do you have any link for that option?

    Workstation Pro v16 also does not work. I get this error: The existing disk file is for a physical disk. Please select "Use a Physical Disk" to reuse an existing physical disk.

    I found out that it works when creating new VMs which is perfectly fine for my need. So I'm happy now, my problem is resolved I tried both v7.0.3 and v8 and they both worked (meaning they accepted RDM disks with *.vmdk pointer files at the time of VM creation from web client). I could not find a way to add RDMs to an existing VM (tried web client, PowerCLI, Workstation Pro 16). Please also note that adding exisiting RDMs to existing guests worked in v6 & v6.5 for me.
