summary: amf: support RESTART admin op on su [#1455]
---
** [tickets:#1455] amf: support for RESTART admin operation on SU.**
**Status:** fixed
**Milestone:** 4.7.FC
**Created:** Wed Aug 19, 2015 08:44 AM UTC by Praveen
**Last Updated:** Fri Sep 11, 2015 04:39 AM UTC
**Owner:** Praveen
Scope of implementation:
1)If su consists of all restartable components, then components in the SU will
be terminated in reverse order of their instantiation level and instantiated
honoring the instantiation level in the configured order. However Component of
same instantiation level are not instantiated or terminated simultaneously.
They are picked one by one as if they belong to different instantiation level.
2)If su consists of atleast one assigned non-restartable component then
SU will be marked OOS and there will be graceful reassignments of all SIs
assigned to this SU to other SU. If no other SU is available to take the
assignments then there will be graceful removal of assignments. This is
applicable to SU of any redundancy model. In this way it becomes spec
deviation for Nway and Nway Active redundancy models in which only assignments
of non-restartable component should be reassigned to other SU.
3)Component presence state during surestart admin operation:
-presence state of a restartable component will remain in Restarting
state when its termination and instantiaion is going on. After successful
instantiation it will move from Restarting to Instantiated state. Thus its
presence state will move from instantiated to restarting and from restarting to
instantiated state.
-presence state of a non-restartable component will transition from
instantiated to terminating state, then from terminating to uninstantiated,
then from uninstantiated to instantiating and finally from instantiating to
instantiated state.
4)For a NPI SU instantiation is done at the time of assignment. So for a NPI SU
which is non restartable, operation will end when it moves to uninstantiated
state.
