Doc Text:
Previously, when deploying an High Availability (HA) environment, VIP interfaces were created with pre-defined MAC addresses. As a result, when a second HA environment was defined, the MAC addresses already existed causing an error. With this update, the pre-defined MAC addresses are generated differently to prevent conflicts. As a result, multiple HA environments are now available.

Description Balaji 2014-10-10 19:41:49 UTC
Description of problem:
When there is more than 1 HA deployment, there is a possibility of conflict (duplication) in MAC address of the VIPs, causing a failure in controller host assignment with the message that the MAC is already existing in an another host.  

Version-Release number of selected component (if applicable):
rhel-osp-installer A1 release

How reproducible:
Deploy with an existing HA deployment

Steps to Reproduce:
1.
2.
3.

Actual results:
Host assignment fails with the message that a MAC is already assigned to a different host.

Expected results:
Host assignment should succeed to the controller host group.

Additional info:

Currently cannot proceed unless the old deployment has been deleted. However the other deployment may need to be preserved for future scaling etc.

Comment 3 Scott Seago 2014-10-13 19:26:24 UTC
The issue is that for the (fake) interfaces we have to create internally to foreman to facilitate IP address reservation, we were just setting the mac addr to 00:00:00:00:00:xx" where the 'xx' corresponds to the VIP number (sequentially from 01).

I've modified this to include deployment ID in the scheme.
