Resolution

Root Cause

  • This error occurs when the SystemID on the system in question (/etc/sysconfig/rhn/systemid) and the SystemID on RHN Classic or Satellite mis-match. In this case, a system will not receive any updates as RHN Hosted or Satellite is unaware of the system. RHN and Satellite maintains profiles for the systems that are registered to it. Every system is identified based on the ServerID. This SystemID on RHN or Satellite should match SystemID listed in "/etc/sysconfig/rhn/systemid" file.

  • Especially, RHEL5 with prior to kernel-2.6.18-200, since there is no {thread,core}_siblings_list in /sys, it might happen, please refer to the following article: RHSM register fails with "No cpu socket information found"

Diagnostic Steps

  • Compare system id with the server ID of the system registered on your RHN account. The output of the above command would be similar to the following:

        # grep ID /etc/sysconfig/rhn/systemid
    <value><string>ID-100100000</string></value>
  • To search system using system ID on RHN, you can follow the below steps:

  1. Search for system on RHN in Advanced Search

  2. Put systemID in search text box.

  3. From "Field to Search:" option select "ID".
  4. Click on Search button.

Traceback observed as well:

There was an error communicating with RHN.
RHN Satellite or RHN Classic support will be disabled.
