** [tickets:#2047] amf: SG unstable when NPI comp in PI SU moves to TERM_FAILED
state during fresh assignments.**

(21.9 kB; application/x-compressed)
Conf: 2N model, one NPI and one PI comp in SU.
Steps to reproduce:
1)Add application using immcfg command.
2)Lock SG.
3)Unlock-in and unlock SUs.
4)Make provisions so that instantiation and clean up scripts of NPI comp
returns with non-zero status.
5)Unlock SG.
When SG is unlocked, AMFND initiates active assignments by issuing callback to
PI comp and by instantiating NPI component. After instantiation failure of NPI
comp, AMFND tries to clean up it. Cleanup fails. AMFND marks comp and SU in
TERM_FAILED state and terminates PI comp also, but AMFND neither responds to
AMFD for the completion of assignment nor it sends any recovery request.
Because of this SG remains unstable in REALIGN state.In this state, no admin
operation is allowed.
Attached are traces and configuration.
Even though issue seems to be similar to #538, it is different in one aspect.
In #538, SU moves to TERM_FAILED state and there is possibiltiy of
failover/switchover as standby assignments are present.
In the present case, it happened during initial assignments and thus there is
no standby to switchover/failover to.
