# Accessing SageMaker HyperPod cluster nodes
<a name="sagemaker-hyperpod-eks-operate-access-through-terminal"></a>

You can directly access the nodes of a SageMaker HyperPod cluster in service using the AWS CLI commands for AWS Systems Manager (SSM). Run `aws ssm start-session` with the host name of the node in format of `sagemaker-cluster:[cluster-id]_[instance-group-name]-[instance-id]`. You can retrieve the cluster ID, the instance ID, and the instance group name from the [SageMaker HyperPod console](sagemaker-hyperpod-operate-slurm-console-ui.md#sagemaker-hyperpod-operate-slurm-console-ui-view-details-of-clusters) or by running `describe-cluster` and `list-cluster-nodes` from the [AWS CLI commands for SageMaker HyperPod](sagemaker-hyperpod-operate-slurm-cli-command.md#sagemaker-hyperpod-operate-slurm-cli-command-list-cluster-nodes). For example, if your cluster ID is `aa11bbbbb222`, the cluster node name is `controller-group`, and the cluster node ID is `i-111222333444555aa`, the SSM `start-session` command should be the following.

**Note**  
If you haven't set up AWS Systems Manager, follow the instructions provided at [Setting up AWS Systems Manager and Run As for cluster user access control](sagemaker-hyperpod-prerequisites.md#sagemaker-hyperpod-prerequisites-ssm).

```
$ aws ssm start-session \
    --target sagemaker-cluster:aa11bbbbb222_controller-group-i-111222333444555aa \
    --region us-west-2
Starting session with SessionId: s0011223344aabbccdd
root@ip-111-22-333-444:/usr/bin#
