A registered client system disappeared from SUSE Manager

SUSE Manager


A client system disappeared from the list of the registered systems in SUSE Manager (i.e. it is not longer registered)

Typically this is a problem when working with imaging/cloning.


First of all it is necessary to find out the client system which has the same Novell Customer Center (NCC) credentials of the disappeared one.

On SLES 11, NCC credentials are saved in file "/etc/zypp/credentials.d/NCCcredentials". See the example below:

# cat /etc/zypp/credentials.d/NCCcredentials

For SLES 12 the same file exists in the same path with the name SCCcredentials.

On SLES 10 systems, NCC credentials are saved in the files /etc/zmd/deviceid and /etc/zmd/secret.
Please note that these files might still exist in a SLES 11 system (specially, but not only, if it was migrated from SLES 10).

Once the client system with the duplicated NCC credentials is found, make the following steps for fixing the issue:
  1. Remove the client systems in SUSE Manager using the web interface.
  2. Run "mgr-ncc-sync" or "mgr-sync refresh" on the SUSE Manager server from command line.
  3. On SLES 11 client systems, move "/etc/zypp/credentials.d/NCCcredentials", "/var/cache/SuseRegister/lastzmdconfig.cache" and "/etc/sysconfig/rhn/systemid" to "/tmp", or simply delete them (on SLES 10 client systems, remove /etc/zmd/deviceid and /etc/zmd/secret, then restart zmd).
  4. On SLES 11, check if /etc/zmd/deviceid and /etc/zmd/secret exist and delete them anyway, even if those files are legacy ones from SLES 10.
  5. On SLES 12, remove "/etc/SUSEConnect"
  6. Run the bootstrap script on the client systems again.
  7. Run again "mgr-ncc-sync" or "mgr-sync refresh" on the SUSE Manager server from command line.


The cause of the issue is that a new client system has been registered using the same NCC credentials of an existing one, causing the override of it. Most likely the two systems were cloned.
