6.2.2 Upgrading to Oracle Linux 7 Update 5 with the Oracle-Supported OFED Packages for UEK R4 installed

The following procedures describe how to upgrade an Oracle Linux 7 system to Oracle Linux 7 Update 5 on a system where the Oracle-supported OFED packages for UEK R4 are already present.

Upgrade using ULN

The following procedure describes how to use ULN to perform an upgrade.

Note

This procedure assumes that you have registered the system with ULN. See Oracle® Linux: Unbreakable Linux Network User's Guide for Oracle Linux 6 and Oracle Linux 7.

  1. Subscribe the system to the ol7_x86_64_optional_latest, ol7_x86_64_UEKR4_OFED, ol7_x86_64_UEKR4, and ol7_x86_64_latest channels on ULN. By default, the ol7_x86_64_UEKR4 and ol7_x86_64_latest channels are enabled when you register an Oracle Linux 7 system with ULN.

  2. Edit the /etc/yum/pluginconf.d/rhnplugin.conf file and add the following lines to the end of the file:

    [ol7_x86_64_UEKR4_OFED]
    priority=20 
  3. Install the yum-plugin-priorities package from the ol7_x86_64_optional_latest channel:

    # yum install yum-plugin-priorities
  4. Apply Oracle Linux 7 Update 5 to the system and use the --exclude=rdma-core* option to avoid a potential package conflict:

    # yum update --exclude=rdma-core* 

    Any Oracle-supported OFED packages for UEK R4 that were already present are updated from the ol7_x86_64_UEKR4_OFED channel. If you do not have any of the OFED packages installed, you can proceed to install the packages as described in the installation instructions provided in Unbreakable Enterprise Kernel: Release Notes for Unbreakable Enterprise Kernel Release 4 Update 6.

Upgrade Using the Oracle Linux Yum Server

The following procedure describes how to use the Oracle Linux yum server to perform an upgrade.

  1. If you updated the server from Oracle Linux 6 or the initial release of Oracle Linux 7, ensure that your system is up to date and that you have transitioned to use the modular yum repository configuration by installing the oraclelinux-release-el7 package and running the /usr/bin/ol_yum_configure.sh script.

    # yum install oraclelinux-release-el7
    # /usr/bin/ol_yum_configure.sh
  2. Enable the ol7_optional_latest and ol7_UEKR4_OFED repositories. By default, ol7_latest and ol7_UEKR4 are already enabled, but you should enable these repositories as well if they are not already enabled.

    # yum-config-manager --enable ol7_latest ol7_UEKR4 ol7_optional_latest ol7_UEKR4_OFED
  3. Install the yum-plugin-priorities package from the ol7_optional_latest repository:

    # yum install yum-plugin-priorities
  4. To apply Oracle Linux 7 Update 5 to the system and use the --exclude=rdma-core* option to avoid a potential package conflict:

    # yum update --exclude=rdma-core*

    Any Oracle-supported OFED packages for UEK R4 that were already present are updated from the ol7_UEKR4_OFED repository on the Oracle Linux yum server. If you do not have any of the OFED packages installed, you can proceed to install the packages as described in the installation instructions provided in Unbreakable Enterprise Kernel: Release Notes for Unbreakable Enterprise Kernel Release 4 Update 7.
