Updates a cluster configuration. You can upgrade the Slurm version, modify scheduler settings, and update accounting configuration for an existing cluster. For more information about upgrading the Slurm version, see Upgrading the Slurm version on a cluster in the PCS User Guide.

You can only update clusters that are in ACTIVE, UPDATE_FAILED, or SUSPENDED state. All associated resources (queues and compute node groups) must be in ACTIVE state before you can update the cluster.

Headers

X-Amz-Target'AWSParallelComputingService.UpdateCluster' required

Request body

clusterIdentifierstring required

The name or ID of the cluster to update.

clientTokenstring

A unique, case-sensitive identifier that you provide to ensure the idempotency of the request. Idempotency ensures that an API request completes only once. With an idempotent request, if the original request completes successfully, the subsequent retries with the same client token return the result from the original successful request and they have no additional effect. If you don't specify a client token, the CLI and SDK automatically generate 1 for you.

Response

Success
