Installing Service Packs for HPC Pack 2008 R2

Updated: August 2011

Applies To: Windows HPC Server 2008 R2

This topic lists the general steps to upgrade HPC Pack 2008 R2 with the latest service pack on the nodes in a Windows HPC Server 2008 R2 cluster.

Note

The latest service pack is HPC Pack 2008 R2 Service Pack 2 (SP2). You must upgrade the head node before you upgrade the other nodes in your cluster. When you apply the service pack to your head node, the files that are used to deploy a compute node or WCF broker node from bare metal are also updated. After the head node is upgraded to SP2, if you install a new node from bare metal or redeploy an existing node, HPC Pack 2008 R2 with SP2 is automatically installed on that node. For detailed installation instructions, see the release notes for each service pack.

Head node

Important

You cannot upgrade the release to manufacturing (RTM) version of HPC Pack 2008 R2 directly to HPC Pack 2008 R2 with SP2. You must install SP1 first. Before you upgrade HPC Pack 2008 R2 with SP1 on the head node to SP2, ensure that you stop all Windows Azure nodes that you previously deployed so that they are in the Not-Deployed state. If you do not do this, you may be unable to use or delete the nodes after the service pack is installed, but charges will continue to accrue in Windows Azure. To use the existing Windows Azure nodes in Windows HPC Server 2008 R2 with SP2, you must restart them after the service pack is installed on the head node.

Step	Description
Install Microsoft HPC Pack 2008 R2 SP1	If you have not yet installed HPC Pack 2008 R2 SP1 on the head node, install it first.
Install Microsoft HPC Pack 2008 R2 SP2	Upgrade HPC Pack 2008 R2 with SP1 to SP2.

Compute nodes and WCF broker nodes

If you deployed compute nodes (or WCF broker nodes) from bare metal, you can redeploy them by using a method such as assigning a node template that reimages the node and automatically installs HPC Pack 2008 R2 with SP2.

To manually install the latest service pack on the compute nodes (or WCF broker nodes) in the cluster, use the steps in the following table.

Step	Description
Install Microsoft HPC Pack 2008 R2 SP1	If you have not yet installed HPC Pack 2008 R2 SP1, install it first.
Install Microsoft HPC Pack 2008 R2 SP2	Upgrade HPC Pack 2008 R2 with SP1 to SP2.

Additional considerations

• You are not required to upgrade workstation nodes on which HPC Pack 2008 R2 (RTM) is installed. However, user activity detection settings that are enabled in the service packs for HPC Pack 2008 R2 are ignored without notification on these workstations. For more information, see Adding Workstation Nodes in Windows HPC Server 2008 R2 Step-by-Step Guide.
