RAC & Failsafe :: Downgrade 2 Node RAC 11.2.0.3 To Previous Version 11.2.0.2 On Test Environment

I wanted to downgrade our 2 node RAC 11.2.0.3 to previous version11.2.0.2 on our test environment, so i could prepare to upgrade production later.

I followed oracle documentation and issued

'/u01/app/11.2.0.3/grid/crs/install/rootcrs.pl -downgrade -oldcrshome /u01/app/11.2.0/grid -version 11.2.0.2.0'

and both nodes and manually removed file in upgraded oracle home (rm -r u01/app/11.2.0.3).

This seems to have caused havoc and ASM and srvctl are no working. lsinvemntory lsinventory still poitns to removed oracle 11.2.0.3

I tried to set

export ORACLE_HOME=$ORACLE_HOME
.oraenv
+ASM1
srvctl config ##n

srvctl config

PRCR-1115 : Failed to find entities of type resource that match filters (TYPE == ora.database.type) and contain attributes DB_UNIQUE_NAME,ORACLE_HOME,VERSION
