Modifies an HSM.


This operation can result in the HSM being offline for up to 15 minutes while the AWS CloudHSM service is reconfigured. If you are modifying a production HSM, you should ensure that your AWS CloudHSM service is configured for high availability, and consider executing this operation during a maintenance window.

--hsm-arn <value>

--hsm-arn (string)

The ARN of the HSM to modify.

--subnet-id (string)

The new identifier of the subnet that the HSM is in. The new subnet must be in the same Availability Zone as the current subnet.

--eni-ip (string)

The new IP address for the elastic network interface (ENI) attached to the HSM.

If the HSM is moved to a different subnet, and an IP address is not specified, an IP address will be randomly chosen from the CIDR range of the new subnet.

--iam-role-arn (string)

The new IAM role ARN.

--external-id (string)

The new external ID.

--syslog-ip (string)

The new IP address for the syslog monitoring server. The AWS CloudHSM service only supports one syslog monitoring server.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.
