can some one explain me what these messages mean?
does it have any thing to do with IO delay?

Responses

I would recommend to open a support case to get your issue solved.

Is it the Host issue? Does it result in IO delay? to whom you want me to open the support ticket Redhat?

It may be a driver issue, but Red Hat is capable enough to investigate, so you can open the case right here: https://access.redhat.com/support/cases/
