Hi!
We are running ovirt 4.3.10 and we are migrating from 3PAR to Dell SC.
I've managed to transfer disks from one LUN away and removed it (put
it in maintenanced, detached it and removed it). Now multipath seems
to spam the logs for missing disks. How can I stop this?
you can remove multipath device either manually or you can use ansible
playbook for it, please try one attached to
https://bugzilla.redhat.com/1310330
see
https://bugzilla.redhat.com/show_bug.cgi?id=1310330#c56
how to use it. You also have to change `hosts` to group of hosts you want to
test on and remove `connection: local`
If it fail, please report back. It can fail as there are stale DM links, see
bugzilla.redhat.com/1928041
this was fixed recently and should be in next oVirt relase.
Alternatively, you can reboot the host.

sdh - tur checker reports path is down
And so on. Any idea how I can quiet this? And why didn't oVirt do this
automatically?
to be able to remove multipath devices, the LUN has to be unzoned first on the
storage server and this cannot be done by oVirt, as oVirt doesn't manage the
storage server - this has to be done by administator of storage server which
has subsequently remove multipath devices from the hosts e.g. by using ansible
script mention above.
Thanks,
Juhani
