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 Andy Grover 2012-12-20 22:13:53 UTC 
This is a kernel/rtslib incompatibility. Using kernel >= 3.6 or rtslib >= 2.1.fb26 will resolve it. I think rhel7 is still pulling updates from Fedora, and should therefore get this fix automatically?
Comment 2 Bruno Goncalves 2012-12-21 09:48:23 UTC 
I have updated the lib to rtslib >= 2.1.fb26.

It seems to have solved the problem, although new one appeared

Comment 3 Andy Grover 2012-12-21 16:53:49 UTC 
please upgrade targetcli to fb18 and that will be resolved.
Comment 4 Andy Grover 2013-01-08 00:06:46 UTC 
Still any issues here or can we close this bz? thx.
Comment 5 Bruno Goncalves 2013-01-08 11:29:56 UTC 
It seems to be working fine with the latest updates:

rpm -q python-rtslib
python-rtslib-2.1.fb28-1.el7.noarch

rpm -q targetcli
targetcli-2.0rc1.fb19-1.el7.noarch
