Release Notes

NOTE: This Solution is applicable only for Red Hat Enterprise Linux 7.5.
Red Hat Enterprise Linux 7 displays incorrect
welcome message
Description: While installing Red Hat Enterprise Linux 7.x, the incorrect variant is displayed in the welcome message.
For example: Welcome to Red Hat Enterprise Linux Client 7.3 (Maipo).
Applies to: Red Hat Enterprise Linux 7.0, 7.1, 7.2, 7.3, 7.4, and 7.5
Cause: This issue occurs due to incorrect references in the ISO build environment at Red Hat.
Workaround: This error message can be ignored because there is no functionality loss.
Red Hat Enterprise Linux 7.4 displays black screen
after iSCSI installation using QLogic QL4xxx cards
with out-of-box drivers
Description: After successful installation of Red Hat Enterprise Linux 7.4 on iSCSI LUN connected to the QLogic
Network (QL4xxx) cards with out-of-box drivers, the system does not login and displays black screen.
Applies to: Red Hat Enterprise Linux 7.4
Cause: The script /usr/libexec/iscsi-mark-root-node does not have qedi transport patch.
Workaround: Make the following change in the script:
>> if [ "$transport" = bnx2i ];
to
>> if [ "$transport" = bnx2i ] || ["$transport" = qedi ];
Unable to discover iSCSI LUN during Red Hat
Enterprise Linux 7 installation with Intel X-550 cards
Description:
Installation of Red Hat Enterprise Linux 7.3 and 7.4 on an iSCSI LUN through Intel-X550 card fails to
automatically discover the iSCSI LUN. This leads to installation failure.
Applies to: Red Hat Enterprise Linux 7.3, 7.4, and 7.5
Cause:
dracut has reduced the wait time to run the interface from seven seconds to five seconds for cases
where interface shows UP but displays NO-CARRIER, for two seconds. Missing out these two seconds,
leads dracut to assume that the interface is not connected, which then leads to failure in LUN discovery.
Workaround:
1. During the iSCSI installations, in addition to boot parameter rd.iscsi.ibft=1, add the following
boot parameter: rd.net.timeout.carrier=7
2. After installation, during boot add the following boot parameter: rd.net.timeout.carrier=7
