  • Once migration failed, unable to re-execute migration script.
# rhn-migrate-classic-to-rhsm
Could not read legacy system id at /etc/sysconfig/rhn/systemid

Resolution

  • Verify whether can see any systemid file under /etc/sysconfig/rhn/ on Red Hat Satellite server. For ex: /etc/sysconfig/rhn/systemid.save.
    If yes then verify whether the ID in that file matches the ID on RHN profile.
# grep ID /etc/sysconfig/rhn/systemid.save

Login to portal and check whether the id matches with the id on satellite profile details page.
If yes then:

# mv /etc/sysconfig/rhn/systemid.save /etc/sysconfig/rhn/systemid
  • On portal go to RHN Classic and edit Red Hat Satellite profile and assign Management entitlement to it. For details refer This content is not included.KCS
  • If satellite is registered with RHN Classic then make sure the sslCACert path in /etc/sysconfig/rhn/up2date file is:
sslCACert=/usr/share/rhn/RHNS-CA-CERT
  • In case systemid file is not present on satellite then register satellite with RHN Classic using rhn_register command.
  • On terminal sync profile and active entitlement certificate forcefully with RHN Classic.
# rhn-profile-sync -vvv
# rhn-satellite-activate -v --rhn-cert=/etc/sysconfig/rhn/rhn-entitlement-cert.xml --force-rhn
  • Clear existing subscriptions data and re-try migration.
# subscription-manager clean
# rhn-migrate-classic-to-rhsm
  • Once migration completed successfully disable extra repos on satellite and enable base and satellite repos only. Then activate certificate.
# subscription-manager repos --disable=*
# subscription-manager repos --enable=rhel-6-server-rpms  --enable=rhel-6-server-satellite-5.7-rpms
# rhn-satellite-activate -v --rhn-cert=/etc/sysconfig/rhn/rhn-entitlement-cert.xml
  • Verify yum and satellite-sync works.
# yum clean all
# yum repolist
# satellite-sync -l

Root Cause

  • 404 error occurred due to temporary issue with RHN.
  • If systemid file is missing then migration failure is expected.
  • Management entitlement missing from satellite server profile on RHN Classic
