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 Wei Liu 2017-06-02 07:48:39 UTC 
Description of problem:
Error message append to rhsm.log when register a system with no installed products and restart the rhsmcertd service.

Version-Release number of selected component (if applicable):
python-rhsm-1.19.8-1.el7.x86_64
subscription-manager-1.19.17-1.el7.x86_64
subscription-manager-gui-1.19.17-1.el7.x86_64
python-rhsm-certificates-1.19.8-1.el7.x86_64
subscription-manager-initial-setup-addon-1.19.17-1.el7.x86_64

How reproducible:
always

Steps to Reproduce:
1.Install build RHEL-7.4-20170601.0
2.remove the system's product cert.
#mv /etc/pki/product-default/*.pem /root/tmp
3.register the system
#subscription-manager register
4.restart the rhsmcertd
#serverice rhsmcertd restart
5.check rhsm.log in /var/log/rhsm/
[root@dhcp-129-210 rhsm]# cat rhsm.log | grep Error
[root@hostname-temp rhsm]# cat rhsm.log | grep -i error
2017-06-02 03:37:22,537 [WARNING] subscription-manager:68646:MainThread @dmiinfo.py:90 - Error reading system DMI information: list assignment index out of range

Actual results:

Comment 4 John Sefler 2017-06-02 13:43:37 UTC 
I am not able to reproduce this error.  Moreover, an Error reading system DMI information sounds like an issue getting the system facts and I can't think of a reason why that would be related to the absence of a product cert.

On that same machine, can you restore the product cert and try to reproduce the DMI error?  If yes, run "rhsm-debug system" and attach the zip file created so that the dev team can troubleshoot.
Comment 5 Wei Liu 2017-06-05 05:36:47 UTC 
For the machine had been returned to beaker,so I tried again one new installed machine and the RHEL build is RHEL-7.4-20170601.0,but failed to reproduce this issue too.The rhsm.log is correct now and no error message.So close it,will reopen it if find this issue later.
Comment 12 Alex Wood 2018-04-09 17:53:39 UTC 
The underlying issue is a regression in python-dmidecode, so I've updated the subscription-manager spec file to require a version equal to or greater than the python-dmidecode version with the fix.
