Upgrading DxEnterprise from the Command Line

Summary​

Upgrading DxEnterprise using the Command Line Interface.

Information​

DxEnterprise software is fully backward compatible and can be updated during normal production without impacting SQL instances or workloads.

caution

If you are running availability groups using tunnels, the tunnel communication between availability group replicas will be impacted until the upgrade completes and the availability group resyncs.

It is also advisable to have access to the node outside of any DH2i tunnels via SSH since access to tunnels will be impacted during the upgrade.

If upgrading DxEnterprise using the DH2i public repository (Linux only) is the preferred method, then please see Upgrading DxEnterprise using the DH2i Repository.

To update DxEnterprise software, please follow one of the procedures below for your operating system:

  1. Download the latest DxEnterprise Software.

  2. Open a command prompt and change directory to the DH2i bin directory.

    cd %ProgramFiles%\DH2i\bin

  3. Freeze the node to disable InstanceMobility. This instructs the cluster not to failover.

    dxcli freeze-node <node_name>

  4. Install the new version of DxEnterprise.

    msiexec /i "DxEnterpriseSetup.<version>.msi" /qn

  5. Unfreeze the node to re-enable InstanceMobility.

    dxcli unfreeze-node <node_name>

  6. Repeat steps 3-5 for each node in the cluster.
