Description Graham Leggett 2015-03-03 00:10:32 UTC
When running the rhn-migrate-classic-to-rhsm command, the expectation was that the system would be deregistered from RHN classic and reregistered with subscription.

This doesn't happen.

Instead, the subscription registration fails, and the machine ends up unentitled and DoSed.

No explanation of any kind is generated during this process to explain why this script doesn't work. The admin is left clicking about the Redhat website in the dark.

This is not a problem with the rhn-migrate-classic-to-rhsm tool.  It is working correctly.  In fact, the tool left you registered using RHSM.

The problem is that your RHSM organization does not appear to have a RHEL subscription available for you to consume.  Maybe they have been exhausted by other consumers.  Log into the customer portal and review what subscriptions are available to your organization.

Or open subscription-manager-gui and review what is on the "All Available" tab.

Or on the command like run "subscription-manager list --all --available"

Comment 3 Graham Leggett 2015-03-03 17:57:22 UTC
It should not be possible for a system that was just unregistered from RHN to suddenly not have enough licenses on subscription-manager - unless subscription-manager is detecting the wrong number of sockets and therefore is applying the wrong number of licenses.

The detect-wrong-sockets bug is raised here: https://bugzilla.redhat.com/show_bug.cgi?id=1198283

Comment 4 John Sefler 2015-03-03 23:06:05 UTC
RHN and RHSM do not share the same entitlement engines.  These are two different technologies.  Relinquishing an entitlement from RHN does not imply that an equivalent entitlement becomes available in RHSM.

Comment 5 Graham Leggett 2015-03-03 23:37:57 UTC
Are you saying that in order to migrate from RHN to RHSM that you need to buy the entitlements again?

What happens to the entitlements in HRN that are released by the rhn-migrate-classic-to-rhsm tool?

Comment 6 Devan Goodwin 2015-04-07 18:52:09 UTC
We do not believe there is a bug here, but you may need to work with your sales rep or global support services to understand why you have no subscriptions available in the RHSM entitlement model.

Comment 7 Graham Leggett 2015-04-07 18:56:13 UTC
Yep, there was a bug here, and was described in https://bugzilla.redhat.com/show_bug.cgi?id=1198283 - it had nothing to do with the sales rep.

In case other people encounter this problem, the Linux kernel misidentifies some boards as having the wrong number of sockets, and this causes the re-registration to fail.

At the advice of the Redhat partner, we have been advised to avoid migrating from classic to rhsm as there are still too many bugs that need working out.
