** [tickets:#78] amf: support for si-swap admin op for Nway model.**

**Status:** review
**Milestone:** 4.7.FC
**Created:** Mon May 13, 2013 04:31 AM UTC by Nagendra Kumar
**Last Updated:** Wed Sep 16, 2015 10:54 AM UTC
**Owner:** Praveen


Migrated from http://devel.opensaf.org/ticket/2073

performing "si-swap" on an si of models NplusM, Nway,NwayActive? is returning 
"ERR_NOT SUPPORTED"


Also there is no mentioning about what the return code should be for "si-swap" 
on NwayActive? and NoRed? Models. 


console output:
amf-adm si-swap safSi=NWayActiveXAppSiorder_SI1,safApp=NWayActiveXAppSiorder
error - saImmOmAdminOperationInvoke_2 admin-op RETURNED: 
SA_AIS_ERR_NOT_SUPPORTED (19)

**Implementation details:**
In this implemntaion for NWAY model, si-swap admin op will be supported with 
following restrictions:
1)Operation will be rejected if Equal distribution feature is enabled.
2)operation will be rejected if SIRankedSU is configured and AutoAdjust flag is
enabled. However it will be allowed if AutoAdjust is disabled.

**Reason for rejecting the operation in above two cases:**
In both of these cases AutoAdjust flag is eanbled and is used to partially
adjust the SG. At the same time, autoadjust feature is used without
using autoadjustprob timer. In the equal distribution cases both active
assignments and standby assignments are equally distributed among the
available SUs without waiting for any autoadjustprob timer expiry.
Thus if si-swap is supported in this case, SG will be adjusted to
same configuration.
Same explanation is valid for other case also.
