SATA disk is seen as SCSI disk by DSM !

[bibicu]

Hi all !

 

First of all, thank you developers for the wonderful work on Xpenology project !

 

Does anyone know why the SATA disks show up as SCSI in DSM virtualized ? This will generate errors in the interface when I check the Health of the disks.

 

I am running DSM 6.2.2, Jun 1.04b, DS918+, in Esxi 6.7 on Asrock J4105-ITX board.

 

I have 3 disks in my VM:

1. the synoboot image (/dev/hda)

2. a virtual disk on SATA1:0

3. a Hitachi hdd on a SATA controller, using PCI Passthrough.

 

synodisk --enum
************ Disk Info ***************
>> Disk id: 1
>> Slot id: -1
>> Disk path: /dev/sda
>> Disk model: Virtual SATA Hard Drive
>> Total capacity: 0.05 GB
>> Tempeture: -1 C
************ Disk Info ***************
>> Disk id: 2
>> Slot id: -1
>> Disk path: /dev/sdb
>> Disk model: Virtual SATA Hard Drive
>> Total capacity: 16.00 GB
>> Tempeture: -1 C
************ Disk Info ***************
>> Disk id: 4
>> Slot id: -1
>> Disk path: /dev/sdd
>> Disk model: HTS545050B9A300
>> Total capacity: 465.76 GB
>> Tempeture: 29 C

 

smartctl --scan
/dev/hda -d ata # /dev/hda, ATA device
/dev/sdb -d scsi # /dev/sdb, SCSI device
/dev/sdd -d scsi # /dev/sdd, SCSI device

 

As you can see the HDD is seen as SCSI.

 

udevadm info --query=property --name /dev/sdd
DEVNAME=/dev/sdd
DEVPATH=/devices/pci0000:00/0000:00:17.0/0000:13:00.0/ata4/host3/target3:0:0/3:0:0:0/block/sdd
DEVTYPE=disk
ID_PART_TABLE_TYPE=gpt
MAJOR=8
MINOR=48
PHYSDEVBUS=scsi
PHYSDEVDRIVER=sd
PHYSDEVPATH=/devices/pci0000:00/0000:00:17.0/0000:13:00.0/ata4/host3/target3:0:0/3:0:0:0
SUBSYSTEM=block
SYNO_DEV_DISKPORTTYPE=SATA
SYNO_INFO_PLATFORM_NAME=apollolake
SYNO_KERNEL_VERSION=4.4
USEC_INITIALIZED=779574

 

So all disks, even though are on SATA controllers show up as SCSI and smartctl fails for them.

 

If I try to get SMART info, I get an error:

 

smartctl -a /dev/sdd

SMART support is: Unavailable - device lacks SMART capability.

 

But if I add -d ata, it works.

SMART support is: Available - device has SMART capability.

 

Anyone can shed some light how to make the disk be seen as SATA instead of SCSI?

 

Thank you !
