          Choosing supported hardware for LLT over RDMA
        2.  
          Installing RDMA, InfiniBand or Ethernet drivers and utilities
        3. Configuring RDMA over an Ethernet network
          1.  
            Enable RDMA over Converged Ethernet (RoCE)
          2.  
            Configuring RDMA and Ethernet drivers
          3.  
            Configuring IP addresses over Ethernet Interfaces
        4. Configuring RDMA over an InfiniBand network
          1.  
            Configuring RDMA and InfiniBand drivers
          2.  
            Configuring the OpenSM service
          3.  
            Configuring IP addresses over InfiniBand Interfaces
        5. Tuning system performance
          1.  
            Tuning the CPU frequency
          2.  
            Tuning the boot parameter settings
        6. Manually configuring LLT over RDMA
          1.  
            Broadcast address in the /etc/llttab file
          2.  
            The link command in the /etc/llttab file
          3.  
            Selecting UDP ports
          4.  
            Configuring the netmask for LLT
          5.  
            Sample configuration: direct-attached links
        7.  
          LLT over RDMA sample /etc/llttab
        8.  
          Verifying LLT configuration
      6. Troubleshooting LLT over RDMA
        1.  
          IP addresses associated to the RDMA NICs do not automatically plumb on node restart
        2.  
          Ping test fails for the IP addresses configured over InfiniBand interfaces
        3.  
          After a node restart, by default the Mellanox card with Virtual Protocol Interconnect (VPI) gets configured in InfiniBand mode
        4.  
          The LLT module fails to start

Upgrading VVR without disrupting replication

This section describes the upgrade procedure from an earlier version of VVR to the current version of VVR when replication is in progress, assuming that you do not need to upgrade all the hosts in the RDS simultaneously.

Note:

On a Cross replication VVR or CVR environment, full upgrade is not supported. Perform a rolling upgrade.

You may also need to set up replication between versions.

See Planning an upgrade from the previous VVR version.

When both the Primary and the Secondary have the previous version of VVR installed, the upgrade must be performed on the secondary site first and primary role shifted to the newly upgraded secondary. The old primary can then be upgraded.

Note:

If you have a cluster setup, you must upgrade all the nodes in the cluster at the same time.
