Tibag Posted March 10, 2021 Share #1 Posted March 10, 2021 Hi all, I currently have a running N45L with DSM via ESXI. It's running with one drive used as my datastore for the VMs (500G) + one data drive (3TB). My DSM VM is like: The first drive is synoboot and the second my data drive. Now I am trying to add 2 more disks to the VM to extend the DSM volume. I'm trying to do a direct mapping so I am trying a passthrough as RDMs. I created my 2 vmdk with vmkfstools then I am trying to add them via a new SCSI controller (SCSI 0:0 and SCSI 0:1). But when I do that DSM is mapping the drives on some obscure slots (like 33). I suspect the issue is with having 2 SATA controllers + the SCSI one. I honestly can't remember why I used a SATA controller for my initial data drive. If I use my existing SATA controller then it's all mapped correctly. So a few questions: Would a SATA controller not allow an actual passthrough? I've read only an SCSI controller will allow that If an SCSI is the only option for the pass though, how can I get it to be mapped by DSM? Should I delete my SATA 2 controller and use an SCSI one instead for the three drives? Will it not confuse DSM with my existing disk that contains data?

flyride Posted March 11, 2021 Share #2 Posted March 11, 2021 If you are using RDM, add them to your second virtual SATA controller. (SATA 1:1, 1:2, etc). Do not use virtual SCSI with DSM 6.2.x Quote Link to comment Share on other sites More sharing options...
