Unable to shut down RHEL 8 when you select Graceful
shutdown option or when you press power button on
the server
Description: When you select the Graceful shutdown option from any system management interface such as iDRAC
or press the power button, the system goes to suspended state and stops all the tasks. So, firmware
updates through iDRAC interface that require restart take longer, and the system is hard reset upon
iDRAC watchdog time expiration.
Applies to: Red Hat Enterprise Linux 8.0
Workaround: Change the power settings by performing the following steps:
1. In the Settings pane, click Power.
2. In the Suspend & Power Button section, from the When the Power Button is pressed list, select
Power Off.
NOTE: By default, Suspend option is selected.
NOTE: The preceding workaround may not work when the system is locked. GNOME prevents
the accidental shutdown when system is locked. As a security precaution, GNOME does not allow
any power related actions such as:
● Shutdown from any system management interfaces like iDRAC
● Pressing the power button unless the user is active and logged in to the operating system.

RHEL 8 does not discover FCoE LUNs connected over
Broadcom BCM57XXX NICs
Description:
On systems with Broadcom BCM57XXX NICs installed, the following cases are observed:
1. When Red Hat Enterprise Linux 8 is installed on FCoE Logical Unit (LUN) as the installation
destination, LUN is not discovered.
2. While upgrading Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 8, and if the current operating
system is installed on FCoE LUN, then the operating system fails to boot.
3. When Red Hat Enterprise Linux 7 is upgraded to Red Hat Enterprise Linux 8, and if FCoE LUN is
connected to the system as data LUN, then LUN is not discovered.
CAUTION: Do not upgrade to Red Hat Enterprise Linux 8 if FCoE LUNs are attached to
Broadcom BCM57XXX NICs. Boot failure or data inaccessibility may result.
Applies to: Red Hat Enterprise Linux 8.0
Cause: From Red Hat Enterprise Linux 8 onwards, the software FCoE is deprecated. When software FCoE
support is not enabled in the operating system, the bnx2fc driver uses the libfcoe module. Since FCoE
works over VLAN 802.1Q, the relevant change needs to be implemented in 802.1Q network module. As
these changes were never done, Red Hat Enterprise Linux 8 fails to discover FCoE LUN connected over
Broadcom BCM57XXX NICs.
Workaround: There is no workaround for this issue.
