During some bad path testing the sibling daemon on each BMC would make it past the existing check done to make sure it was running and then die. This would cause the wait for the sibling interface to be on D-Bus to time out. At that point each BMC became active since it thought the sibling daemon was fine and just the sibling BMC had the problem. Fix this by checking again if the sibling daemon is running when the sibling interface still isn't on D-Bus after waiting for it. If it isn't, become passive. Tested: This is seen on each BMC: ``` Waiting for sibling interface and/or heartbeat: Present = False, Heartbeat = False Done waiting for sibling. Interface present = False, heartbeat = False Sibling service state is failed Role = xyz.openbmc_project.State.BMC.Redundancy.Role.Passive due to: Sibling BMC service is not running ``` Change-Id: Id065e547462ea1c944e00c127552cc4642ce6744 Signed-off-by: Matt Spinler <[email protected]>
