nodeIds

A list of EC2 instance IDs to replace with new hardware. You can specify between 1 and 25 instance IDs.

Replace operations destroy all instance volumes (root and secondary). Ensure you have backed up any important data before proceeding.

• Either NodeIds or NodeLogicalIds must be provided (or both), but at least one is required.

• Each instance ID must follow the pattern i- followed by 17 hexadecimal characters (for example, i-0123456789abcdef0).

• For SageMaker HyperPod clusters using the Slurm workload manager, you cannot replace instances that are configured as Slurm controller nodes.
