We have 2 new AFF A300 system that came preinstalled with OnTap 9.6p2.  Our exisiting clusters of FAS8040 are running 9.5p5.  We'd like to downgrade A300s to Ontap 9.5.  What are proper procedures for downgrading nodes?  Our A300s are connnected to cluster switches (not part of cluster) but should we connect A300 nodes together when downgrading OnTap?  Our goal is to downgrade A300s to OnTap 9.5 then initalize with ADPv2.

FYI to those interested, we contacted support and after some digging they fouind a stale smf table entry blocking new nodes trying to joing the cluster.  

 

Although Nodes 3 and 4 had the same version of ONTAP as the existing cluster they would not join because there was a stale entry in the smf tables.

4 entries were displayed.

 

There should be an entry for each node in the Cluster plus 1 entry for the Cluster.  

 

We removed the 8.3P1 entry:

::*> debug smdb table cluster_version_replicated delete -uuid 3101b6df-7cec-11e5-8e37-00a0985f3fc6

 

Note:  Do not edit the smf tables without guidance from NetApp Support.
