1049200 – cannot create vn2vn instance via fcoeadm

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.

Comment 1 Xiaowei Li 2014-01-07 08:23:06 UTC

fcoe-utils-1.0.29-2.el7.x86_64

Comment 3 Petr Šabata 2014-01-14 13:54:51 UTC

Just like in bug #1046226, could you retry with SELinux disabled and post any AVC messages you get, if applicable?

Comment 4 Xiaowei Li 2014-01-21 03:25:18 UTC

retry with SELinux disabled. and still get the same issue. It seems like the option "-m vn2vn" does not work. it always use the Fabric mode to create the FCoE instance.

Comment 7 Xiaowei Li 2014-02-26 09:49:31 UTC

set it to blocker since vn2vn is the rhel 7.0 fcoe feature. we should support it via the fcoeadm.

As there is a workaround, I don't believe this meets the blocker criteria.

okay for me to remove the blocker keyword. but let's keep the urgent priority so that we can fix it asap.

also if cannot fix it in 7.0 we should document this known issue.
