Hi,
I've got simple dataguard configuration primary on normal fs and
standby Standalone GI with role separation (grid unix user for GI+ASM
and oracle for oracle) .
All generally works flawlessly until second switchover where something
kills my oracle instance in GI configuration .
As a workaround I can just simply srvctl start database -d orcl2 .
Below some details (11.2.0.4) .

Suspecting GI but can't prove it right now :) .
Any ideas ?
