Problem passing through disks to VM

[NickH]

I have a VM which currently has 2 disks passed through to it. I would like to pass another 2 disks through to it. However, when I try

qm set 117 -scsi3 /dev/disk/by-id/ata-TOSHIBA_MG09ACA18TE_62X0A100FJDH

It just sits there forever. If I change -scsi3 to -scsi5, it works. Do you know what is going on? Could scsi3 be in use somewhere? if so, where? It is not mentioned in any conf file in /etc/pve/nodes/pve/qemu-server.

is the vm running? what does 'qm config 117' say?

I tried multiple times with the VM running and not running and every time it hung, but when I tried scsi4 it worked for the other disk (even with the VM running). I then tried scsi5 with this disk and it worked immediately.

what does the host syslog say (e.g. with 'journalctl -b') ? any disk (or other) errors?

I can see where it worked:

It looks like the VM was running when I did this and there is no mention of scsi3 (so where it hung):
