Registering a machine with Red Hat Satellite 6 fails with error "Validation failed: Attached to can't be blank"

Solution Verified - Updated

Environment

  • Red Hat Satellite 6.6
  • Red Hat Satellite 6.11 and above

Issue

  • Registering a machine with Red Hat Satellite 6.6 whose primary interface is a bonded interface fails with the following error:

      # subscription-manager register --org="RedHat" --environment="Library"
 Registering to: satellite.example.com:443/rhsm
 Username:xxxxxxxx
 Password: 
 HTTP error (422 - Unknown): Validation failed: Attached to can't be blank

  • A similar problem has resurfaced in Red Hat Satellite 6.11 and later, as well.

Resolution

  • This issue has been reported to the Red Hat Engineering team and has been fixed via Bugzilla This content is not included.1766344 and This content is not included.1769898.

  • Please upgrade to Red Hat Satellite 6.6.3 or 6.7 to fix this problem and retry the registration.

  • In case the problem is observed with Red Hat Satellite 6.11 or later versions, then there are two possibilities to look into.

    • The name of the BOND or VLAN-tagged interface perhaps includes a hyphen(-) or underscore(_) whereas, by design, Red Hat Satellite cannot recognize a name with such pattern e.g. bond-prime. For this example, The end-user needs to rename the interface to bondprime and then retry the registration.

    • If a VLAN-tagged interface has any UPPERCASE letters in the name, then that is also something the satellite cannot recognize. It has been reported to the Red Hat Engineering team via This content is not included.Bugzilla 2250397. Reach out to This content is not included.Red Hat Technical Support for any further assistance or clarification required.
