Hi All,
I think patch for this ticket can be pushed in other branches also because we
are retaining both the definitions. If a user sets it to 1 then default value
will remain 1. If a user sets it to 0 then default value will be
PrefAssignedSUs. A user has always the facility to lock the SI for no
assignments.
Thanks,
Praveen

** [tickets:#1190] AMF: saAmfSIPrefActiveAssignments has wrong default,
stopping scaling nway active SGs**
**Status:** fixed
**Milestone:** 5.2.FC
**Created:** Thu Oct 23, 2014 01:10 PM UTC by Hans Feldt
**Last Updated:** Fri Feb 24, 2017 06:15 AM UTC
**Owner:** Praveen
Problem: In naway-active, SUs are not instantiated unless
saAmfSIPrefActiveAssignments is configured.
saAmfSIPrefActiveAssignments is a configuration attribute only valid for the
nway-active redundancy model.
According to the spec 3.6.5.3 it should have a default value of "the preferred
number of assigned service units."
and
"saAmfSGNumPrefAssignedSUs" should have a default value of "the preferred
number of in-service service units"
and
"saAmfSGNumPrefInserviceSUs" should have a default value of "the number of the
service units configured for the service group."
The value of saAmfSIPrefActiveAssignments is currently set to one when not
configured, instead it should be set to saAmfSGNumPrefAssignedSUs.
In order to avoid any backward compatibility issue, choice is left to the user
for default value of the attribute.
Default value of saAmfSIPrefActiveAssignments will be either
saAmfSGNumPrefAssignedSUs or 1
based on user choice.
Following are conditions in which different default values will be honoured:
-if a user configures saAmfSIPrefActiveAssignments=1 then SI will assigned to
only one
SU.This is to ensure backward compatibility.
-if a user does not configure attribute saAmfSIPrefActiveAssignments in
application or
deletes this attributes via CCB operation then AMFD will still honor default
value as 1. This
is again to ensure backward compatibility.
-if a user sets saAmfSIPrefActiveAssignments=0 via CCB or in application conf
then AMFD will
use section 3.6.5 definition for default value i.e saAmfSGNumPrefAssignedSUs.
