Issue 1 Clearly, Oracle RAC ASM mode, OCR is stored in ASM and ensures that the ASM instance starts before booting

The ASM instance was not brought up since the server was restarted. We must manually start the ASM instance

Sqlplus/? Sysasm Startup After starting the ASM instance we start the cluster-related resources [Email protected] ~]# Crsctl start has [[email protected] ~]# Crsctl start CRS [[email protected] ~]# CRSCTL Check CRS Crs-4638:oracle High Availability Services is online Crs-4537:cluster Ready Services are online Crs-4529:cluster Synchronization Services is online Crs-4533:event Manager is online Launch instance resources, etc. Crsctl Start Cluster–all
