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
| `- 9:0:0:0  sdb 8:16 active ready running
`-+- 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.

device {
                vendor                  "QNAP"
                product                 "iSCSI Storage"
                path_grouping_policy    "failover"
                path_selector           "round-robin 0"
                path_checker            readsector0
                prio                    weightedpath
                prio_args               "hbtl 9:0:0:0 9 10:0:0:0 1"
                uid_attribute           ID_SERIAL
        }
