Release Notes

Red Hat Enterprise Linux 7.4 with QLogic QL41xxx
rNDC cards ping fails
Description: On Dell EMC's yx4x PowerEdge servers with Red Hat Enterprise Linux 7.4 communication fails on
QL41xxx Qlogic rNDC cards
Applies to: Red Hat Enterprise Linux 7.4 with firmware version 14.02.15
Cause: Incompatible driver with latest firmware
Workaround: Use Qlogic drivers version 8.23 provided by Dell EMC.
Solution: Update Qlogic drivers from www.access.redhat.com/errata/RHEA-2017:3489.
SRIOV VFs of Mellanox cards interfaces are named
incorrectly
Description: On Dell EMC PowerEdge servers with Mellanox ConnectX Network cards, if SRIOV is enabled and VFs are
created, the network interfaces are displayed incorrectly.
Applies to: Red Hat Enterprise Linux 7.3 and 7.4
Cause: There is a race condition between the Virtual Function link creation in sysfs and calling the mlx_5core
driver. The Virtual Function links should be created in sysfs before calling the driver to avoid the race
condition.
Workaround: Disable biosdevname by entering boot parameter biosdevname=0. This leads to systemd naming of
interfaces.
