My customer is seeing loss of access to FC attached SAN on b-series blades that have windows and Red Hat installed bare metal, VMware are fine just these 2 OS's. It happens when the 6100 fails over to the subordinate. They say they reboot the servers 4-5 times before they are live on the fabric again as intended. They have many UCS systems in many environments with differing versions of firmware and too many variables to list here, looking to see if anyone seen and rectified this, possible drivers for 2008r2 and RH ???
thx
