closed QNAP product attribute is incorrect #576

@stormi, @olivierlambert

Thanks to everyone, I was able to complete it.
Thank you very much!!

Hello,

The QNAP setting in multipath.conf is incorrect. The settings cannot be called correctly because the product attribute is different. It seems to work with default values.

I will feed back my experience to XCP-NG project.

product attribute - [Underbar is incorrect. Space is correct]

/etc/multipath.xenserver/multipath.conf.old

device {
                vendor                  "QNAP"
                product                 "iSCSI_Storage"
        }

/etc/multipath.xenserver/multipath.conf

device {
                vendor                  "QNAP"
                product                 "iSCSI Storage"
        }

I was editing multipath.conf to give priority to multipathing sessions.
I started debugging because the settings didn't apply. You have noticed a difference in the call string "iSCSI Storage".

[16:30 xxxxxxxxx etc]# multipath -ll
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx dm-0 QNAP    ,iSCSI Storage   
size=20T features='1 queue_if_no_path' hwhandler='0' wp=rw
|-+- policy='round-robin 0' prio=9 status=active

`-+- policy='round-robin 0' prio=1 status=enabled
  `- 10:0:0:0 sdc 8:32 active ready running

By replacing the underscore with a space, the setting is now recognized correctly and the session can be given priority.

closed QNAP product attribute is incorrect #576

I wrote two blocks of underscores and spaces in my QNAP environment.
A forward match was detected and two blocks were read as separate configurations.
This method lists both old and new, so I don't think there will be any problems if old QNAPs use underscores.

I will try to contact github.

I don't know if the QNAP specifications have changed.
I searched past information.

I found another post of 2019 year. In this post, it was "iSCSI Storage". (Spaced)

I found official QNAP report of 2018 year. it was "iSCSI Storage". (Spaced)

I found Citrix forum of 2018 year. it was "iSCSI Storage". (Spaced)

It's not smart, but you might be able to follow both old and new by listing two blocks of underbars and spaces. In my debugging, I made a distinction between underbars and spaces, so I thought it would be solved by writing two blocks.

I put two blocks in my server's multipath.conf, check it and reply. Please give me some time.
Are there any commands or logs you would like me to check?
