Hi
This is the first time I have posted a question on here.
I am attempting to deploy a Self Hosted Engine with RHV 4.4.8, RHEL 8.4 using a PowerFlex
(ScaleIO) volume. I have done this several times in the past with oVirt 4.3.x and 4.4.?
but for some reason on this occasion I am hitting a problem. I think I might know what it
is but I don't know how to fix it. The deployment appears to go fine up until the
point where the question is asked about which storage device I want the HE copied to, I
select Fibre Channel but unfortunately this fails and does not find any suitable devices -
I know that PowerFlex is not technically FC but the devices are recognised by multipathd
and have always worked previously (I was instrumental in getting the udev rules changed in
the PowerFlex 3.6 version to ensure the devices could be recognised by multipathd, whereas
previously it had required a udev rules edit).
The device I am trying to use is this:
# multipath -v2 -l
1abc8aad74a6630f-c4c045df00000000 dm-2 ##,##
size=120G features='1 queue_if_no_path' hwhandler='0' wp=rw
`-+- policy='service-time 0' prio=0 status=active
`- #:#:#:# scinia 252:0 active undef running
I can see in the log that the device is being partially discovered but it seems that a
'vendor_id' is wanted and this is something that udev does not report for a
PowerFlex device.

QUESTION/1/OVEHOSTED_STORAGE_DOMAIN_TYPE=str:'fc'
Is there any way I can edit something to prevent this vendor_id being required?
As I said, this has worked previously so I can only assume something has been added that
now checks this vendor_id
Many thanks in advance
