# Get hardware information for each HSM in an AWS CloudHSM cluster with CMU
<a name="cloudhsm_mgmt_util-getHSMInfo"></a>

Use the **getHSMInfo** command in the AWS CloudHSM cloudhsm\_mgmt\_util (CMU) to get information about the hardware on which each hardware security module (HSM) runs, including the model, serial number, FIPS state, memory, temperature, and the version numbers of the hardware and firmware. The information also includes the server ID that cloudhsm\_mgmt\_util uses to refer to the HSM.

Before you run any CMU command, you must start CMU and log in to the HSM. Be sure that you log in with a user type that can run the commands you plan to use.

If you add or delete HSMs, update the configuration files for CMU. Otherwise, the changes that you make might not be effective for all HSMs in the cluster.
