batchRebootClusterNodes

Reboots specific nodes within a SageMaker HyperPod cluster using a soft recovery mechanism. BatchRebootClusterNodes performs a graceful reboot of the specified nodes by calling the Amazon Elastic Compute Cloud RebootInstances API, which attempts to cleanly shut down the operating system before restarting the instance.

This operation is useful for recovering from transient issues or applying certain configuration changes that require a restart.

• Rebooting a node may cause temporary service interruption for workloads running on that node. Ensure your workloads can handle node restarts or use appropriate scheduling to minimize impact.

• You can reboot up to 25 nodes in a single request.

• For SageMaker HyperPod clusters using the Slurm workload manager, ensure rebooting nodes will not disrupt critical cluster operations.
