Updating your nim image
The default sample x CAT HPC Integration files may not support all the product updates as soon as they are available.
Be sure to review all package lists, bundle files, scripts, and other files that you are using to ensure they will work correctly for the product updates you are installing.
This can be the location of the source code or the name of another NIM lpp_source resource.
If you have used the x CAT IBM HPC Integration support to initially install HPC software on your cluster nodes, you can apply product updates to your cluster in several different ways.
The method you choose will depend upon many factors: As with all product updates, you will need to be aware of any new operating system dependencies, any changes required to the product configuration, or any changes to operational procedures for administering or using the product.
If you only wish to do one or two of those options, or run the operations in a different order, specify the correct flags to the updatenode command. Use this method for updating your HPC software if you are confident that you are applying stable updates that you wish to commit to your existing compute node image and you have a scheduled maintenance window for your cluster.
You can use this approach for all diskless nodes, either stateless or statelite, Linux or AIX.
This method will not work if the products are currently installed in read-only directories in statelite or AIX diskless clusters.
