# DetachClusterNodeVolume
<a name="API_DetachClusterNodeVolume"></a>

 Detaches your Amazon Elastic Block Store (Amazon EBS) volume from a node in your EKS orchestrated SageMaker HyperPod cluster.

 This API works with the Amazon Elastic Block Store (Amazon EBS) Container Storage Interface (CSI) driver to manage the lifecycle of persistent storage in your HyperPod EKS clusters. 

## Request Syntax

{
   "ClusterArn": "string",
   "NodeId": "string",
   "VolumeId": "string"
}
```

## Request Parameters
<a name="API_DetachClusterNodeVolume_RequestParameters"></a>

For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

The request accepts the following data in JSON format.

 ** [ClusterArn](#API_DetachClusterNodeVolume_RequestSyntax) **   <a name="sagemaker-DetachClusterNodeVolume-request-ClusterArn"></a>
 The Amazon Resource Name (ARN) of your SageMaker HyperPod cluster containing the target node. Your cluster must use EKS as the orchestration and be in the `InService` state.   
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 256.  
Pattern: `arn:aws[a-z\-]*:sagemaker:[a-z0-9\-]*:[0-9]{12}:cluster/[a-z0-9]{12}`   
Required: Yes

 ** [NodeId](#API_DetachClusterNodeVolume_RequestSyntax) **   <a name="sagemaker-DetachClusterNodeVolume-request-NodeId"></a>
 The unique identifier of the cluster node from which you want to detach the volume.   
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 256.  
Pattern: `i-[a-f0-9]{8}(?:[a-f0-9]{9})?`   
Required: Yes

 ** [VolumeId](#API_DetachClusterNodeVolume_RequestSyntax) **   <a name="sagemaker-DetachClusterNodeVolume-request-VolumeId"></a>
 The unique identifier of your EBS volume that you want to detach. Your volume must be currently attached to the specified node.   
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 256.  
Pattern: `vol-[a-f0-9]{8}(?:[a-f0-9]{9})?`   
Required: Yes

## Response Syntax
<a name="API_DetachClusterNodeVolume_ResponseSyntax"></a>

```
{
   "AttachTime": number,
   "ClusterArn": "string",
   "DeviceName": "string",
   "NodeId": "string",
   "Status": "string",
   "VolumeId": "string"
}
```

## Response Elements
<a name="API_DetachClusterNodeVolume_ResponseElements"></a>

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

 ** [AttachTime](#API_DetachClusterNodeVolume_ResponseSyntax) **   <a name="sagemaker-DetachClusterNodeVolume-response-AttachTime"></a>
 The original timestamp when your volume was initially attached to the node.   
Type: Timestamp

 ** [ClusterArn](#API_DetachClusterNodeVolume_ResponseSyntax) **   <a name="sagemaker-DetachClusterNodeVolume-response-ClusterArn"></a>
 The Amazon Resource Name (ARN) of your SageMaker HyperPod cluster where the volume detachment operation was performed.   
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 256.  
Pattern: `arn:aws[a-z\-]*:sagemaker:[a-z0-9\-]*:[0-9]{12}:cluster/[a-z0-9]{12}` 

 ** [DeviceName](#API_DetachClusterNodeVolume_ResponseSyntax) **   <a name="sagemaker-DetachClusterNodeVolume-response-DeviceName"></a>
 The device name assigned to your attached volume on the target instance.   
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 32.  
Pattern: `/dev/(xvd[a-z]|sd[b-z]|sd[f-p][1-6])` 

 ** [NodeId](#API_DetachClusterNodeVolume_ResponseSyntax) **   <a name="sagemaker-DetachClusterNodeVolume-response-NodeId"></a>
 The unique identifier of the cluster node from which your volume was detached.   
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 256.  
Pattern: `i-[a-f0-9]{8}(?:[a-f0-9]{9})?` 

 ** [Status](#API_DetachClusterNodeVolume_ResponseSyntax) **   <a name="sagemaker-DetachClusterNodeVolume-response-Status"></a>
 The current status of your volume detachment operation.   
Type: String  
Valid Values: `attaching | attached | detaching | detached | busy` 

 ** [VolumeId](#API_DetachClusterNodeVolume_ResponseSyntax) **   <a name="sagemaker-DetachClusterNodeVolume-response-VolumeId"></a>
 The unique identifier of your EBS volume that was detached.   
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 256.  
Pattern: `vol-[a-f0-9]{8}(?:[a-f0-9]{9})?`
