RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Doc Text:
.FCoE option is changed to rd.fcoe Previously, the man page for `dracut.cmdline` documented `rd.nofcoe=0` as the command to turn off Fibre Channel over Ethernet (FCoE). With this update, the command is changed to `rd.fcoe`. To disable FCoE, run the command `rd.fcoe=0`. For further information on FCoE see, https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/configuring-fibre-channel-over-ethernet_configuring-and-managing-networking[Configuring Fibre Channel over Ethernet]

https://beaker.engineering.redhat.com/recipes/9565391#installation


works well with RHEL-8.4.0-20210210.n.0 and dracut-049-133.git20210112.el8.x86_64

Comment 1 Lukáš Nykrýn 2021-02-17 08:22:07 UTC
Can you please add rd.debug on kernel cmdline and post here the logs? Also does this work when you drop rd.nofcoe=1 completely?

Comment 2 guazhang@redhat.com 2021-02-17 13:44:24 UTC
It works well after remove rd.nofcoe parameter from kernel line or rd.nofcoe=0

Comment 3 David Tardon 2021-02-18 09:51:29 UTC
Well, what do you expect should happen when you explicitly *disable* FCoE?

Comment 10 Petr Matyáš 2021-08-11 12:34:15 UTC
Verified on dracut-049-188.git20210802.el8.x86_64

option is now called rd.fcoe, with 0 disabling FCoE
