Changing the admin password for Cisco UCS Manager

Yes, I know changing the admin password isn’t rocket science and it’s easy enough to do but what I noticed was that those who are not familiar with what you can left or right click in UCS Manager may have problems getting to the proper window to do it.  Also, I did a quick search on Google for this an noticed that the first 5 results are always about resetting a lost admin password which was when I thought: “Why don’t I write this blog post to help anyone that might be searching for it?”

Changing the admin account password with the GUI

Log into UCS Manager and navigate to the Admin tab, drill down the nodes: All –> User Management –> User Services –> Locally Authenticated Users –> admin and open the General tab:

In the General tab, type in the new password in the Password and Confirm Password text box then click Save Changes button located at the bottom right hand corner.

Changing the admin account password with CLI

To disable this via the CLI, SSH to your fabric interconnect’s IP address and login.  Proceed and type the following commands:

  1. scope security
  2. set password
  3. commit

The CLI will ask you to enter the new password, then confirm it after you’ve typed in step #2.  Make sure you issue the 3rd command: commit or else the changes will not take effect.

The output should look something like this:

login as: admin

Fairly simple to do.

I changed the admin password in UCSM, as you instructed. But when I try to join the new FI to the cluster, it still will not take it to let the new FI to join cluster. What else can I do? I really do not want to reboot the existing FI to do the password recovery. This is a production enviroment
