Database Software

Hi All

i have a 11gR2 RAC instance with 2 nodes running 11.2.0.3 on OEL 5 update 8 64-bit environment

After a physical restart of the node1 the cluster on node1 do not start

When i try to run the below command on node1

$GRID_HOME/bin/crsctl check crs


the following error is shown

CRS-4638: Oracle High Availability Services is online
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4530: Communications failure contacting Cluster Synchronization Services daemon
CRS-4534: Cannot communicate with Event Manager

Cluster in node 2 and db instance on node 2 is up and running.

When i try to run the below command on node1

# ps -ef | grep d.bin
