6.12.1 Using ISO Images to Image a New System

You can download ISO images to use when upgrading your Oracle Exadata.

In versions prior to 12.1.2.2.0, ISO images are available as patches that you can download for bare metal imaging an Exadata system. This is now the default method in 12.1.2.2.0 and above. You are no longer required to build the ISO files using imagemaker. Patches are available for both database nodes and cells. You can use the ISO images to boot the server using a virtual media device on the ILOM (from the Devices menu of the ILOM console). For example, the two ISO images available for 12.1.2.1.1 are listed in the following table.

To prepare a new Exadata system for deployment using ISO images, perform the following steps:

  1. Obtain the latest Oracle Exadata Deployment Assistant (OEDA).

  2. Run the OEDA configuration tool to generate the configuration files. You will need the configuration files when you run applyElasticConfig.sh later.

  3. Power on all the servers.

    1. Database nodes and cells will automatically assign to themselves unused IP addresses on eth0 in the 172.16 range.

    2. Host names of the nodes will be of the format nodeN, where N is a number.

  4. After booting from the ISO, follow the prompts and imaging will start automatically. You will be prompted to enter IP addresses.

    You can use a preconf.csv by following the steps in Using ISO to Image a New System to mount the image on an NFS repository. You need to place the preconf.csv file in the same NFS directory.

  5. If you are using virtualization on the database servers (Oracle VM Server or Oracle Linux KVM), then run switch_to_ovm.sh on each database server. The database servers will reboot if you are using Oracle VM Server.

    For example:

    # /opt/oracle.SupportTools/switch_to_ovm.sh
2014-12-07 11:58:36 -0800 [INFO] Switch to DOM0 system partition /dev/VGExaDb/LVDbSys3 (/dev/mapper/VGExaDb-LVDbSys3)
2014-12-07 11:58:36 -0800 [INFO] Active system device: /dev/mapper/VGExaDb-LVDbSys1
2014-12-07 11:58:36 -0800 [INFO] Active system device in boot area: /dev/mapper/VGExaDb-LVDbSys1
2014-12-07 11:58:36 -0800 [INFO] Set active systen device to /dev/VGExaDb/LVDbSys3 in /boot/I_am_hd_boot
2014-12-07 11:58:36 -0800 [INFO] Reboot has been initiated to switch to the DOM0 system partition

  6. On systems with InfiniBand Network Fabric only, run /opt/oracle.SupportTools/reclaimdisks.sh -free -reclaim on each database server before installing any software.

    The command reclaims disk space reserved for the deployment type not selected, which is not required on RoCE-based Exadata database servers.

    The command typically takes less than 5 minutes.

    Caution:

    Do not skip this step. Skipping this step results in unused space that can no longer be reclaimed by reclaimdisks.sh. 
    # /opt/oracle.SupportTools/reclaimdisks.sh -free -reclaim

  7. If you have an Oracle Exadata Rack X8 or earlier, then run ibhosts and verify that all nodes show the correct IP addresses and host names. There should be no nodes with elasticNode in the description.

  8. Run the OEDA tool to deploy.

    [root] # ./install.sh -cf ../MAA-dm01.xml -l
