Multiple physical drives

[Jan Kristensen]

Hi All..

I have just started to use Proxmox in my lab, but I have an issue that I really hope someone can help me with..

For some testing of Windows Storage spaces I wanted to map 4 physical drives to one of my vm's, i have tried some diffrent methods of mapping the drives..

qm set 101 --virtio1 /dev/disk/by-id/ata-drive1
qm set 101 --virtio2 /dev/disk/by-id/ata-drive2
qm set 101 --virtio3 /dev/disk/by-id/ata-drive3
qm set 101 --virtio4 /dev/disk/by-id/ata-drive4

This seems to work, i can see 4 scsi controllers and 4 scsi drives in windows device manager, but in the windows management console i can only see one of the drives. It is the same in powershell, only one drive listed.

Then I tried to change to the Megaraid scsi controller.

qm set 101 --scsihw megasas --scsi1 /dev/disk/by-id/ata-drive1
qm set 101 --scsihw megasas --scsi2 /dev/disk/by-id/ata-drive2
qm set 101 --scsihw megasas --scsi3 /dev/disk/by-id/ata-drive3
qm set 101 --scsihw megasas --scsi4 /dev/disk/by-id/ata-drive4

Now I only have one controller, but sadly also only one drive in device manager.

Last i tried to create 4 virtual disks, and map them to the megaraid, that works just fine.

qm set 101 --scsi1 local-lvm:vm-101-disk1,size=100G
qm set 101 --scsi2 local-lvm:vm-101-disk2,size=100G
qm set 101 --scsi3 local-lvm:vm-101-disk3,size=100G
qm set 101 --scsi4 local-lvm:vm-101-disk4,size=100G


The issue is only when I try to use the physical disks.

Anyone have an idea how I can get the 4 drives mapped to my windows vm, the right way..

are the disks properly formatted? i know in windows you have to first initialize the disks with the
disk management tool (or named similar)

Hi, I have tried with raw unformated and paritioned drives, same result, only the one with SCSI ID 1 can be used..

As said the virtual drives i create works fine, all 4 are shown in disk management, I can see the SCSI ID of them all, and are ready for initialisation.

As far as I can tell this happens only with physical disks..
