Uh . hmmm . No ? On second thought , let me change that to no , definitely not on the internet , ever . There we are . <| sep |> ik u want some more blue gems bby <| sep |> Turns out that two things were happening . 1 , I tested my setup in VMware Workstation and RDM failed there . If I added the option disk . enableUUIDTRUE to my vmx file , it started working in workstation . 2 . The disk does not expose VPD 83 . I was actually also waiting on an upgrade to a PERC H 310 card . Once I installed this in the server , the PERC itself began exposing VPD 83 for all the disks I attach to it , even plain SATA disks in passthrough mode . in other words solved ! You need either a VPD 83 capable drive , or a RAID controller that will inject a response for inquiry page 83 for you like the PERC H 310 .
