Replaces specific nodes within a SageMaker HyperPod cluster with new hardware. BatchReplaceClusterNodes
terminates the specified instances and provisions new replacement instances with the
same configuration but fresh hardware. The Amazon Machine Image (AMI) and instance
configuration remain the same.
This operation is useful for recovering from hardware failures or persistent issues that cannot be resolved through a reboot.
Data Loss Warning: Replacing nodes destroys all instance volumes, including both root and secondary volumes. All data stored on these volumes will be permanently lost and cannot be recovered.
To safeguard your work, back up your data to Amazon S3 or an FSx for Lustre file system before invoking the API on a worker node group. This will help prevent any potential data loss from the instance root volume. For more information about backup, see Use the backup script provided by SageMaker HyperPod.
If you want to invoke this API on an existing cluster, you'll first need to patch the cluster by running the UpdateClusterSoftware API. For more information about patching a cluster, see Update the SageMaker HyperPod platform software of a cluster.
You can replace up to 25 nodes in a single request.
For .NET Core this operation is only available in asynchronous form. Please refer to BatchReplaceClusterNodesAsync.
