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.

Description Qian Cai 2012-05-23 03:08:19 UTC 
+++ This bug was initially created as a clone of Bug #815981 +++

fcoe-target.init is still applying tcm_start.sh on service start instead of using saveconfig.json. This means that rebooting the machine will not retain fcoe target configuration
Comment 1 Qian Cai 2012-05-23 03:11:10 UTC 
This is to track the remaining issue.

FAILED QA.

restart fcoe-target daemon can restore configure, BUT reboot CANNOT.

This is output after reboot:
====
[root@storageqe-13 ~]# targetcli ls /
targetcli ls /

fcoe            0:off   1:off   2:on    3:on    4:on    5:on    6:off
fcoe-target     0:off   1:off   2:on    3:on    4:on    5:on    6:off
====

When fcoe-target start, chances are fcoe daemon not yet setup FCoE port. So targetcli refuse to create non-exist target.

Workround: 

Put this line into /etc/rc.local:
====
service fcoe-target restart
====

Possible solutions:
1. fcoe daemon only quit after all FCoE session created. (fcoe need a standalone tool for OS boot for this, like iscsi have iscsistart tool) 

2. Change fcoe-target daemon to S99, but still have chances for failure.

3. Devs use magic.

Comment 9 Andy Grover 2012-05-17 14:06:52 EDT 

Petr, how to we ensure fcoe setup is complete before fcoe-target setup?

Comment 10 Petr Šabata 2012-05-22 10:00:21 EDT

You can't really ensure that.  Anything could go wrong.

The best thing you could do at the moment is check the output of fcoeadm, possibly in a loop with a timeout.

Comment 11 Andy Grover 2012-05-22 18:20:36 EDT

yuck, but ok. So:

If there are configured fcoe targets, grep the output of fcoeadm -i until they show up and then proceed.

What should the timeout be?

Comment 12 Andy Grover 2012-05-22 18:49:51 EDT

Changes too big and too late for 6.3. Nominating for 6.3.z and 6.4.
Comment 3 Andy Grover 2012-05-25 15:48:34 UTC 
The workaround fit better in python-rtslib package: python-rtslib-2.1.fb12-3.el6.
Comment 5 Gris Ge 2013-01-23 09:04:06 UTC 
VERIFY.

fcoe-target-utils-2.0rc1.fb16-3.el6.noarch and python-rtslib-2.1.fb21-1.el6.noarch works well for config save and restore.
