This error is bogus, you can ignore it.

It was fixed in 4.2 by not trying to get pv info for a lun that was just
added an likely will not have pv info.

Re: [ovirt-users] FC LUN

[Стаценко Константин Юрьевич]

Zoning is correct. Mutipath shows this LUN on every host in the DC.

Hi, Konstantin.

What “multipath -ll” command says? Execute on every node that have access to 
the SAN.

Is any zoning on SAN fabrics?

Hello!

Can you, please, help ?

There is a strange error while trying to connect FC LUN from the old SAN 
storage system to oVirt 4.1.9 hosts.

In the same time there are no problems with LUN’s from other storage systems.

The error in vdsm.log is:
