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

Use the **info** command in the AWS CloudHSM cloudhsm\_mgmt\_util (CMU) to get information about each of the hardware security modules (HSM) in the AWS CloudHSM cluster, including the host name, port, IP address and the name and type of the user who is logged in to cloudhsm\_mgmt\_util on 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.
