Change root and nm2user Passwords - Oracle® SuperCluster M8 and SuperCluster M7 Security Guide

Language:

Change `root` and `nm2user` Passwords

The IB switch maintains system accounts in two locations. The root and nm2user accounts are configured and exposed by the switch's underlying OS. Adding, removing, or changing accounts is not supported at this layer, but you can changevpasswords.

For other accounts and passwords, see Change IB Switch Passwords (Oracle ILOM).

The IB switch does not have the ability to define or enforce password complexity, aging, history, or other rules. You must ensure that passwords assigned comply with U.S. Department of Defense password complexity requirements and processes are implemented to ensure passwords are updated in accordance with U.S. Department of Defense policy.

For more information on IB switch account management, including how to create new accounts, assign permissions to existing accounts, or remove accounts, refer to the Oracle Sun Data Center InfiniBand Switch 36 Hardware Security Guide and the Oracle Integrated Lights Out Manager Supplement for the Oracle Sun Data Center InfiniBand Switch 36. See Additional IB Switch Resources.

Note - When a password is changed for any SuperCluster component that Oracle Engineered Systems Hardware Manager manages (such as the IB switches), you must also update the password in Oracle Engineered Systems Hardware Manager. For details, refer to the Oracle SuperCluster M8 and SuperCluster M7 Administration Guide.

Log into the IB switch as root.
```
# ssh root@IB_Switch_IP_address
```
See Default User Accounts and Passwords.

Change the root password.
```
$ passwd root
```

Change the nm2user password.
```
$ passwd nm2user
```
