Direct map of SATA disk in ESX 7
asked on
I'm having a weird issue with this procedure under ESX 7.0u2 to directly connect SATA drives to a VM.
I manage to present the pass-through disks following the instructions but after a few disks (I have 10 physical 2Tb SSD devices I want to pass-through to a VM) I get the dreaded "Incompatible device backing specified for device (device number)" error.
By few I mean it is a random number. I always manage to connect 2 disks but after that it is a random process... sometimes I manage more, sometimes not ! It seems to be a bug as I eventually, by keeping trying, managed to connect up to 8 disks. Once they are declared everything seems to work absolutely fine (did some pretty involved stress testing and it seems rock solid).
If anyone has further comments I am most interested !

- Tried SCSI or SATA controller - no difference
- Tried to manually edit the VMX file but it does not seem to work (at all)
- Tried to have the vmdk files in a different storage - doesn't help
If anyone has further comments I am most interested !
