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 Aaron Thomas 2014-02-07 16:12:41 UTC 
Customer has purchased an 8246-L1D. It has an 8-core Power7+ processor and is similar to a 710 that contains 8 cpu's on one socket. The system is not subscribing correctly, and detecting a higher socket count in RHSM. I


This is reproducible on customer's server, by registering the system and removing and registering the system again. 


The hardware is linux specific, has one socket and consistently shows 4 sockets on RHSM.

Comment 6 Ken Hitchcock 2014-03-11 16:36:40 UTC 
I have been sent a similar issue as per below. But this time its on a Citrix XenServer. 

As up to RHEL 6.3 (kernel-2.6.32-220.el6.x86_64) the subscription-manager command would return the following:

As of RHEL 6.4 (kernel-2.6.32-358.18.1.el6.x86_64) the subscription-manager command would return the following:

I suspect this (incorrect socket count on Xen) is more likely related to https://bugzilla.redhat.com/show_bug.cgi?id=844532


This bug (1062661) seems to be ppc46 LPAR specific.
Comment 8 Adrian Likins 2014-03-27 16:45:22 UTC 
I think this is the same issue as https://bugzilla.redhat.com/show_bug.cgi?id=1070908

ppc64 lpar systems add a /sys/devices/system/cpu/cpu* entry for each cpu thread available to the physical system (regardless if they are associated with that lpar). Code was previously assuming a cpu* entry meant a cpu available to the system (similar to other arches). But that is not true for ppc64 lpar systems.

The fix for 1070908 is to ignore cpu* entries that do not provide any cpu topology information. With that change, the count of cpu threads drops to 8, and
the topo info is calculated as:


'cpu.core(s)_per_socket' : '1'
'cpu.cpu(s)' : '8'
'cpu.cpu_socket(s)' : '2'
'cpu.thread(s)_per_core' : '4'
'cpu.topology_source' : 'kernel /sys cpu sibling lists'


Now, this is where things get complicated. For what the kernels considers a 'socket', that is a 2 socket machine. IBM, however, considers that a single socket (by a different definition of socket) machine.
Comment 10 Brent Baude 2014-05-06 20:16:15 UTC 
Can RH provide the patch for this and also a test package?
Comment 11 John Jarvis 2014-05-09 19:51:49 UTC 
IBM is signed up to test and provide feedback, setting OtherQA.
Comment 18 Joseph Kachuck 2014-12-02 14:46:43 UTC 
Hello IBM,
Please confirm if you would be able to run:
# yum update subscription-manager
on RHEL 6.6 install.

Then test if this issue has been corrected.

Thank You
Joe Kachuck
Comment 19 Joseph Kachuck 2014-12-02 14:48:09 UTC 
Hello IBM,
This should be fixed in subscription-manager-1.12.14-7.el6 and above.

Thank You
Joe Kachuck
Comment 20 John Sefler 2014-12-16 13:42:38 UTC 
As stated in the comments above, this issue should already be addressed by the fix for bug 1070908 and is available in subscription-manager-1.11.2-1 and newer.  RHEL 6.6 was released with subscription-manager-1.12.14-7.el6 which includes the fix.  Please re-open if the problem continues after running...

yum update subscription-manager
subscription-manager facts --update
