6.2 Oracle-Supported RDMA Packages

Oracle Linux 7 Update 7 introduces UEK R5 as the default kernel. The Oracle-supported RDMA packages that are shipped with UEK R5 replace previous OFED packages and use an updated package and channel-naming scheme. Oracle recommends using UEK R5 with Oracle Linux 7 Update 7. If you intend to install RDMA packages, see Unbreakable Enterprise Kernel: Release Notes for Unbreakable Enterprise Kernel Release 5 Update 2.

Upgrading a system with an existing UEK R5 installation

If you are upgrading your system from a release prior to Oracle Linux 7 Update 7 and you are already using UEK R5 with the Oracle-supported RDMA packages, these packages are updated automatically as part of the upgrade process.

If your system is registered with ULN, ensure that it is subscribed to the ol7_x86_64_UEKR5_RDMA, ol7_x86_64_UEKR5, and ol7_x86_64_latest channels before the upgrade.

If your system uses the Oracle Linux yum server, ensure that the ol7_UEKR5_RDMA, ol7_UEKR5, and ol7_latest repositories are enabled before upgrading.

Upgrading a system with an existing UEK R4 installation to use UEK R5

If you are upgrading your system from a release prior to Oracle Linux 7 Update 7 and you are using UEK R4 with the Oracle-supported OFED packages, it is recommended that you upgrade to UEK R5 and switch to the corresponding Oracle-supported UEK R5 RDMA packages before upgrading your system.

Note that if the system is newly registered on ULN, the ol7_x86_64_UEKR5 and ol7_x86_64_latest channels are subscribed to by default. However, you will need to explicitly subscribe to the ol7_x86_64_UEKR5_RDMA channel.

If your system uses the Oracle Linux yum server, the ol7_UEKR5, and ol7_latest repositories are enabled by default, starting with Oracle Linux 7 Update 6. However, ensure that the ol7_UEKR5_RDMA repository is enabled before upgrading.

Upgrading requires that you remove existing OFED packages prior to installing the compatible packages for UEK R5. For instructions, see Unbreakable Enterprise Kernel: Release Notes for Unbreakable Enterprise Kernel Release 5 Update 2.

Upgrading a system with an existing UEK R4 installation to continue to use UEK R4

If you are upgrading your system from a release prior to Oracle Linux 7 Update 7 and you are using UEK R4 with the Oracle-supported OFED packages, and you intend to continue to use UEK R4, you must ensure that your system is subscribed to the correct channels or that the correct yum repositories are enabled before upgrading.

If you are using ULN, check that your system is registered before upgrading and then subscribe the system to the ol7_x86_64_UEKR4_OFED and ol7_x86_64_UEKR4 channels.

Warning

By default, the ol7_x86_64_UEKR5 and ol7_x86_64_latest channels are enabled when you register an Oracle Linux 7 Update 7 system with ULN. Note that if the ol7_x86_64_UEKR5 channel is enabled, you must disable it to continue if you plan to continue to use UEK R4 with the Oracle-supported OFED packages.

If you are using the Oracle Linux yum server, check that the ol7_UEKR4 and ol7_UEKR4_OFED repositories are enabled and make sure that the ol7_UEKR5 and ol7_UEKR5_RDMA repositories are disabled.

Use the yum update command to upgrade to Oracle Linux 7 Update 7 with the UEK R4 compatible OFED packages.

If you do not have any of the OFED packages installed, you can proceed to install the packages as described in the installation instructions that are provided in Unbreakable Enterprise Kernel: Release Notes for Unbreakable Enterprise Kernel Release 4 Update 7.
