Error reading device using LVM on CentOS with iSCSI E-Series volume

I have a CentOS 7 system (3.10.0-957.12.2.el7.x86_64) with Unified Host Utilities 7.1 installed and multipathd configured & enabled.

 

When I run pvcreate on the /dev/mapper/xxxx devices I get a series of errors below, although the command then completes successfully.  Is there any configuration I can use which will suppress these errors?
