    I tried but still same problem, it is not comming up, please see below.

    Node2[/etc] #init.crs stop
    Shutting down Oracle Cluster Ready Services (CRS):
    Stopping resources. This could take several minutes.
    Error while stopping resources. Possible cause: CRSD is down.
    Shutdown has begun. The daemons should exit soon.


    node2[/etc] #init.crs start
    Startup will be queued to init within 30 seconds.


    $ crsctl check crs
    CSS appears healthy
    Cannot communicate with CRS
    Cannot communicate with EVM

    node2[/opt/crs/oracle/bin] #crs_stat -t

    Did you look at the logs?

    As per Oracle documentation -which is great by the way

    $ORA_CRS_HOME/crs/log Contains trace files for the CRS resources.
    $ORA_CRS_HOME/crs/init Contains trace files of the CRS daemon during startup. Good place to start with any CRS login problems.
    $ORA_CRS_HOME/css/log The Cluster Synchronization (CSS) logs indicate all actions such as reconfigurations, missed check-ins, connects, and disconnects from the client CSS listener. In some cases, the logger logs messages with the category of auth.crit for the reboots done by Oracle. This could be used for checking the exact time when the reboot occurred.
    $ORA_CRS_HOME/css/init Contains core dumps from the Oracle Cluster Synchronization Service daemon (OCSSd) and the process ID (PID) for the CSS daemon whose death is treated as fatal. If abnormal restarts for CSS exist, the core files will have the format of core..
    $ORA_CRS_HOME/evm/log Log files for the Event Volume Manager (EVM) and evmlogger daemons. Not used as often for debugging as the CRS and CSS directories.
    $ORA_CRS_HOME/evm/init PID and lock files for EVM. Core files for EVM should also be written here.
    $ORA_CRS_HOME/srvm/log Log files for Oracle Cluster Registry (OCR), which contains the details at the Oracle cluster level.
    $ORA_CRS_HOME//log Log files for Oracle Clusterware (known as the cluster alert log), which contains diagnostic messages at the Oracle cluster level. This is available from Oracle database 10g R2.
