CloudHSM / Client / create_hsm



This is documentation for AWS CloudHSM Classic. For more information, see AWS CloudHSM Classic FAQs, the AWS CloudHSM Classic User Guide, and the AWS CloudHSM Classic API Reference.

For information about the current version of AWS CloudHSM, see AWS CloudHSM, the AWS CloudHSM User Guide, and the AWS CloudHSM API Reference.

Creates an uninitialized HSM instance.

There is an upfront fee charged for each HSM instance that you create with the CreateHsm operation. If you accidentally provision an HSM and want to request a refund, delete the instance using the DeleteHsm operation, go to the AWS Support Center, create a new case, and select Account and Billing Support.


It can take up to 20 minutes to create and provision an HSM. You can monitor the status of the HSM with the DescribeHsm operation. The HSM is ready to be initialized when the status changes to RUNNING.


This operation is deprecated and may not function as expected. This operation should not be used going forward and is only kept for the purpose of backwards compatiblity.
