HTTP error (400 - Bad Request): Problem creating unit ConsumerDTO [uuid: null, name: hostname, owner id: null]

Resolution

  • From the systems page in RHSM, click the New button. Provide the required information to finish creating the new system profile.
  • Copy the UUID of the system from the details tab under Basic Information.
Basic Information

Name       (none)
Type       Virtual System/Physical System
UUID       xxxx-yyyy-zzzz-abbb
  • Register the system using the below command:
# subscription-manager register --consumerid=<UUID>       <<--Paste the UUID
  • In case of registering client vm to Satellite server, make sure the subscription-manager rpm on the client is updated to the latest version available.

Root Cause

  • System UUID missing in subscription-manager facts.

  • As the system UUID was missing in subscription-manager facts, In order to register the system as a separate entity to Customer Portal the system should have a unique hostname and UUID.

  • Some older versions of subscription-manager rpm on client system exhibit this behavior while registering with Satellite server.

Diagnostic Steps

  • Check if the hostname and UUID of the system are present in system information by using the subscription-manager facts command:
# subscription-manager facts | grep -i uuid

# subscription-manager facts | grep -i hostname
