When starting Oracle RAC 12c the following error appears :-
[root@—— bin]# ./crsctl check cluster
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4530: Communications failure contacting Cluster Synchronization Services daemon
CRS-4534: Cannot communicate with Event Manager
CRS-5013: Agent “ORAROOTAGENT” failed to start process “/grid/app/12.1.0.2/bin/osysmond” for action “start”: details at “(:CLSN00008:)” in “/grid/app/oracle/diag/crs/……/crs/trace/ohasd_orarootagent_root.trc”
The cause :- DB Node was reboot.
To solve this issue :-
CRS-2672: Attempting to start ‘ora.crf’ on CRS-2674: Start of ‘ora.crf’ on failed CRS-2679: Attempting to clean ‘ora.crf’ on (Doc ID 1902447.1)
