Red Hat Satellite 6 WebUI or hammer shows too few errata applicable for some host.

Solution Verified - Updated -

Environment

  • Red Hat Satellite 6.x

Issue

  • yum update or yum updateinfo on a Content Host shows many errata applicable.
  • Red Hat Satellite 6 WebUI and also hammer shows less errata for content host.
  • How to make Red Hat Satellite aware about all applicable errata?

Resolution

  • There are several options on how to recalculate errata applicability, either of them can be used:

    1) Run below command on the affected Content Host:

     # dnf uploadprofile --force-upload

    OR

    2) On the Content Host do any one of the below

    • (Un)install any package
    • Enable or disable a repository
    • Unregister and re-register the Content Host to Red Hat Satellite/Capsule.

    OR

    3) Run the underlying task on Red Hat Satellite directly - for any affected Content Host(s) that can be specified via variable hosts:

     # foreman-rake console
  irb(main):001:0> User.current = User.anonymous_admin
  irb(main):002:0> hosts = Host.all
  irb(main):002:0> hosts = [Host.find(Katello::System.find_by_uuid("ac97b210-c4b8-48ec-96cd-75251cf594a0").host_id)]
  irb(main):002:0> hosts = [Host.find_by_name("contenthost.example.com")]
  irb(main):003:0> ForemanTasks.sync_task(::Actions::Katello::Host::GenerateApplicability, hosts)

    NOTE The first option triggers the task for each and every Content Host. The second for the host of given UUID (subscription-manager identity run on the Content Host shows the UUID), and the third for given hostname.

Root Cause

  • Applicability is calculated via GenerateApplicability task, which must be run after any change in packages on a Content Host or after any change in a repository associated to a Content Host.

  • When this task was skipped or failed due to some error, there is a workaround in manually invoking it - either via some triggering activity on the Content Host (see points 1) and 2)) or directly invoking the task (point 3)).
