[PVE-User] VIOSCSI, WSFC, and S2D woes - Solved! & RFE

Tried that this morning, no luck. Not having much luck finding anything about 83h in vioscsi, but I did find a few things:
Most of that is related to pointing vioscsi at a remote iscsi target though, instead of my use case of a local disk image/block device.
Later - I got it working!
I had to specify the wwn and serial parameters on the -device parameter, like so:
-device scsi-hd,bus=scsihw0.0,channel=0,scsi-id=0,lun=1,drive=drive-scsi1,id=scsi1,wwn=0x5000c50015ea71ad,serial=yCCfBgH1\ <- note the wwn= and serial= parameters
Currently testing this out by running the vm manually, looks like I'll have to add this disk via the args: entry in <vmid>.conf, which is acceptable.
I suppose at this point we can call this a RFE to expose the wwn= and serial= parameters in the api in some future version.
Might be able to randomly generate wwn/serial entries, but I don't know nearly enough about the sas protocols to say whether this is a good idea or not.
Some more references that I found:
https://bugzilla.redhat.com/show_bug.cgi?id=831102 <- this is the one that got me on the right track finally.
Full kvm command is here for those interested:

afaics from the bug report, this should be fixed since 2016 if their changes made it into the upstream qemu (unknown, since they do not disclose what needs to change) our qemu version should include it
you can try to upgrade to a current version (PVE 5.3, with qemu 2.12.1) and use the most recent virtio drivers
