I'm sorry, I send it here by mistake. Wanted to send it to libvirt-user list.
Sorry for that.

Hi,
I'm trying to find the root cause for BZ #1898049 [1]. When setting up
Windows HA cluster on Windows Server VMs run on top of oVirt, Windows
cluster validator runs couple of tests and fails during test "Validate
SCSI-3 Persistent Reservation" and one of the VMs of the cluster is paused
with IO error. Disk definition is as follows:
<disk type='block' device='lun' sgio='unfiltered'
snapshot='no'>
<driver name='qemu' type='raw' cache='none'
error_policy='stop'
io='native'/> <source
dev='/dev/mapper/3600a09803830447a4f244c4657616f6f'
index='1'> <seclabel model='dac' relabel='no'/>
<reservations managed='yes'>
<source type='unix'
path='/var/lib/libvirt/qemu/domain-1-Windows-2016-2/pr-helper0.sock'
mode='client'/> </reservations>
</source>
<backingStore/>
<target dev='sdb' bus='scsi'/>
<shareable/>
<alias name='ua-26b4975e-e1d4-4e27-b2c6-2ea0894a571b'/>
<address type='drive' controller='0' bus='0'
target='0' unit='1'/>
</disk>
and libvirt error I get is bellow [2].
When I try to create reservation from Windows VM manually, I get following
error (but not sure I do it whole process correctly):
.\sg_persist --out --register --param-sark=123abc e:
QEMU QEMU HARDDISK 2.5+
Peripheral device type: disk
PR out (Register): command not supported
sg_persist failed: Illegal request, Invalid opcode
Do you have any ideas what could be wrong or how to determine
the root cause of this this issue?
Thanks in advance.
