** [tickets:#1605] smfd: campaign not correctly terminated after failed SI-SWAP
**
**Status:** fixed
**Milestone:** 5.0.2
**Created:** Thu Nov 19, 2015 12:26 PM UTC by Ingvar Bergström
**Last Updated:** Thu Oct 06, 2016 01:34 PM UTC
**Owner:** Alex Jones
Scenario:
1)smfd order a SI-SWAP to continue the campaign execution on the other
controller.
2)before swap is executed, an imm object "SmfRestartIndicator" is created to
signal to the smf on the new controller the campaign restart was initiated by
smf (spontaneus restarts will always fail the campaign in executing state).
3)When the new controller comes up smf will check the existence of the object.
If present OK if not fail. If OK the "SmfRestartIndicator" object is removed.
In this case the new controller fail to start very early, before smf was
started. Smf never have a chance to remove the object.
5)AMF order a switchback to the first controller.
6)Smf start up on the "old" controller once again. Since the
"SmfRestartIndicator" is still there, smf think the restart was ordered by smf
and try to continue campaign execution which fail (the wrong way e.g. core dump)
Todo: find a mechanism which make smf to detect the "SmfRestartIndicator" is
the old one and treat this case as it does not exist. Make sure the new
solution is backward compatible.
The campaign continues at:
file: SmfUpgradeCampaign.cc, method:SmfUpgradeCampaign::continueExec()
The restart indicator is handeled in:
file: SmfUpgradeCampaign.cc,
method:SmfUpgradeCampaign::checkSmfRestartIndicator()
