Nodes unavailable for selection from the OUI Node Selection screen

After successfully installing the grid infrastructure, The second node is not available fr selection while installing the database software.I am installing Release 11.2.0.1 on OEL 5.8 running on Esxi. These are two nodes And am using /etc/hosts file for IP resolution. cluster services are online on both nodes. I have even restarted them as per the docs but still can't see the node.

    Is the oracle home clustered, i.e when you installed the database software home was it scped to the second node in the cluster ?

    Thanks

    I have two users, grid and oracle. These are the environments

    Oracle:

    Node1:

    [oracle@OELRacNode1 ~]$ env|grep ORA

    ORACLE_BASE=/u01/app/oracle

    [oracle@OELRacNode1 ~]$

     

    Node2:

    [oracle@OELRacNode2 ~]$ env|grep ORA

    ORACLE_BASE=/u01/app/oracle

    [oracle@OELRacNode2 ~]$

    This means I haven't set $ORACLE_HOME for the user oracle on both nodes before running the runInstaller for the database software.

    User grid:

    Node1:

    [grid@OELRacNode1 ~]$ env|grep ORA

    ORACLE_BASE=/u01/app/11.2.0/grid

    [grid@OELRacNode1 ~]$

     

    Node2:

    [grid@OELRacNode2 ~]$ env|grep ORA

    ORACLE_BASE=/u01/app/11.2.0/grid

    [grid@OELRacNode2 ~]$

     

    Password-less ssh has been set for the user grid:

    [grid@OELRacNode2 ~]$ ssh grid@OELRacNode1

    I installed the grid infrastructure as grid

    I am installing rdbms as oracle.

    Hi I suspect

    Either 1) the shared storage is not actually shared i.e it picked up the wrong locations and hence separate ocr has been created or 2) the gid users uid etc is not same across the different servers ?

    At this point I would suggest you open an Sr if you have support...

    Thanks

    Thank you very much. Like you said '1) the shared storage is not actually shared', This was true So I set up the shared disks on the VSphere 5 carefully as described on 'Oracle Databases on VMware RAC Deployment Guide' and everything worked just fine.
