  • How to move a system from RHSM to RHN Classic.

Resolution

1) Only the following plugins should be listed if the system is registered to RHSM:

[root@localhost ~]# yum check update
Loaded plugins: refresh-packagekit, subscription-manager, product-id

2) Check to see if the rhn plugins are installed, or install plugins needed for RHN Classic:
To check:

[root@localhost ~]#  rpm -qa rhn-setup

To install:

[root@localhost ~]# yum install rhn-setup

3) Unregister and remove any local traces from RHSM as necessary:

[root@localhost ~]# subscription-manager unregister
[root@localhost ~]# subscription-manager clean

4) Change directory to edit plugins:

[root@localhost ~]# cd /etc/yum/pluginconf.d

5) List current plugins:

[root@localhost pluginconf.d]# ls
product-id.conf          rhnplugin.conf
refresh-packagekit.conf  subscription-manager.conf

6) Edit plugins on system, enable plugins needed for RHN Classic:

[root@localhost pluginconf.d]# vim rhnplugin.conf 

[main] 
enabled = 1 
gpgcheck = 1 

[root@localhost pluginconf.d]# vim product-id.conf 

[main] 
enabled = 0 
gpgcheck = 1 

[root@localhost pluginconf.d]# vim subscription-manager.conf 

[main] 
enabled = 0 
gpgcheck = 1
  • RHN Classic Plugins:
    • rhnplugin.conf
    • refresh-package.conf

  • RHSM Plugins

    • product-id.conf
    • refresh-package.conf
    • subscription-manager.conf

  • Enabled = 1

  • Disabled = 0

7) Clean yum cache:

[root@localhost pluginconf.d]# yum clean all
Loaded plugins: refresh-packagekit, rhnplugin
Cleaning up Everything

8) Register system to RHN Classic via command-line:

[root@localhost pluginconf.d]# rhnreg_ks --username=<your RHN ID> --password=<your RHN password>
