elmuziko Posted October 1, 2016 Share #1 Posted October 1, 2016 Evening all Hopefully someone can help me. I've got a new ESXi 6 set up. I used the guide here (viewtopic.php?f=15&t=5255) to set up the VM but used the latest VMDK image rather than build my own. I've managed to power the machine on and can get to the install so I know the image is OK, but when I try to add any raw drives it won't let me. I used Xpenology member Cyanlabs video guide ( ) on how to map RDM's. I have 2 WD3 TB drives each is it's own datastore with a folder called RDM inside, and a VMDK of what i assume is itself. When I go to add a disk the RDM option is greyed out. When I point to the VMDK file I get "Incompatible device backing #0" I read on the internet to go to settings and disable RdmFilter.HbaIsShared I get the same error. Any ideas?

elmuziko Posted October 2, 2016 Author Share #2 Posted October 2, 2016 OK so I've had no luck wish ESXi 6, so gone back to version 5.5 Slightly more luck, the VM builds now but when I try to attach a RDM drive it says the file failed to lock. I have a VDMK of the machine within its own datastore\RDM\Drive.vmdk Is that normal behaviour? Or do I need the VMDK file else where? Ta Link to comment Share on other sites More sharing options...
mmaeso Posted October 8, 2016 Share #3 Posted October 8, 2016 When you say "I have 2 WD3 TB drives each is it's own datastore" do you mean that you have created a VMware datastore on top of each disk? Link to comment Share on other sites More sharing options...
