     Add all of the cluster nodes hostnames and Virtual IP hostnames on the Cluster Node Information

    On the Specify Network Interface Usage screen, make sure that the public and private interfaces are
    properly specified. Make the appropriate corrections on this screen and click Next to continue.
    NOTE: The public and private interface names MUST be consistent across the cluster, so if Public is public and Private is private, the same MUST be true on all of the other nodes in the cluster.

     Choose Automatic Storage Management (ASM) on the Storage Option Information screen and
    click Next to create the ASM diskgroup for Grid Infrastructure.

     On the Create ASM Disk Group screen perform the following:
    • Enter the Disk Group Name that will store the OCR and Voting Disks
    • Choose  for the Redundancy level.

    d:\OraGrid) on the Specify Installation Location screen. Click Next to allow the OUI to perform
    the prerequisite checks on the target nodes.
    Continuing with failed prerequisites may result in a failed installation; therefore it is recommended that failed prerequisite checks be resolved before continuing.

    After the prerequisite checks have successfully completed, review the summary of the pending installation and click Finish to install and configure Grid Infrastructure.

    On the Finish screen click Close to exit the OUI.

    Once the installation has completed, check the status of the CRS resources as follows:
    All resources should report as online with the exception of GSD and OC4J? . GSD will only be online if Grid Infrastructure is managing a 9i database and OC4J? is reserved for use in a future release. Though these resources are offline it is NOT supported to remove them.
    cmd> %GI_HOME%\bin\crsctl stat res -t
