auto attach does not attach VDC subscription after VM is migrated to another host

Solution Verified - Updated

Environment

  • Red Hat Enterprise Linux (RHEL) 6.10
  • Red Hat Enterprise Linux (RHEL) 7
  • subscription-manager-1.20.10-8.el6.x86_64 and below
  • subscription-manager-1.24.13-3.el7_7.x86_64
  • additional Red Hat Products installed, for example JBoss Enterprise Application Platform 7.2

Issue

  • After migration of a VM subscriptions seems to get lost.
  • If a system has two products installed and executes subscription-manager attach --auto to subscribe the RHEL product, it fails, even though there is a subscription available.

Resolution

  • Red Hat is aware of this behavior and is being addressed in the Bugzilla This content is not included.1759006.

  • As a workaround please follow the steps below

    • Removing all product subscriptions and running auto attach works.
        # subscription-manager remove --all
    # subscription-manager attach --auto
    • To verify all subscriptions 
       # subscription-manager list --installed
   # subscription-manager list --consumed

Root Cause

  • Auto attach will not mix SLAs once a system has at least one subscription attached with a particular SLA.

  • More concretely, that JBoss subscription has an SLA of "Premium". Once that JBoss subscription is attached, auto attach will not attach the VDC subscription which is SLA "standard".

Diagnostic Steps

  1. Have RHEL and JBoss product installed and migrate the VM to another Hypervisor

  2. Start with JBoss subscription subscribed and RHEL not subscribed

  3. Run the subscription-manager command to attach the subscription

        # subscription-manager remove --all
       local certificates have been deleted.
       subscriptions removed at the server.

    # subscription-manager attach --pool 
         8a99f9ad6d5fa32c016d6240568a01a4
         Successfully attached a subscription for: Red Hat JBoss Enterprise 
         Application Platform, 64-Core Premium

    # subscription-manager attach refresh
        local certificate has been deleted.
        All local data refreshed

     # subscription-manager attach --auto
