Fixed In Version: ovirt-3.4.0-beta1

Previously, maintenance on a hosted engine and an HA-enabled host were completed using separate maintenance flows. A get_local_host_id() method was added to the high availability client API. Now, the maintenance flows are unified.

Description Greg Padgett 2014-01-15 15:50:56 UTC 
+++ This bug was initially created as a clone of Bug #1047649 +++
(Cloned for submission of a new ha client api needed to properly read local host's ha status from the ha client.)

Description of problem:
Currently hosted engine has its own flows to maintenance the engine VM and another flow to maintenance an HA-enabled host.

These flows should be unified with the existing host maintenance flows.

This BZ was created for the engine side, but another may be needed for VDSM to support HA-maintenance request from the engine.

setting target release to current version for consideration and review. please do not push non-RFE bugs to an undefined target release to make sure bugs are reviewed for relevancy, fix, closure, etc.
Comment 1 Greg Padgett 2014-01-27 16:11:57 UTC 
Added a get_local_host_id() method to the ha client api.  For testing, if the HA status shows up in webadmin for a host on which it is configured, then this API is working.

Hi Greg, can you say the best way to verify this bug.
Thanks

Hi Artyom.  Currently, you can check the ovirt-hosted-engine-ha changes by calling the new api with a short python script on a node in the ha cluster.  Something like this would work, and if it returns the host id, then this paticular bug/patch is working:

  import ovirt_hosted_engine_ha.client.client as haClient
  print haClient.HAClient().get_local_host_id()

Once all other patches for this feature are merged (see bug 1047649 and bug 1053040) then this will be testable as part of the overall feature--if the feature works in the engine UI, then this bug/patch works as well.
