Dear colleagues,

We can't connect EVA4400 LUN's to virtual Guest Machine Centos 7 through virtual Fibre Channel. On the same configuration Guest Machine with Windows 2012 R2 works normally.

Can you run 'fdisk -l', and show us the output?

I had the same results with RHEL 7. After re-installing the OS I could see the disk just fine. Is there any solution to this other than a fresh install?
