Recovering a Lost Password
Password Recovery for the Admin Account
The admin account is the system administrator or superuser account. If an administrator loses the password to this account, you can have a serious security issue. As a result, the procedure to recover the password for the admin account requires you to power cycle all fabric interconnects in a Cisco UCS instance.
When you recover the password for the admin account, you actually change the password for that account. You cannot retrieve the original password for that account.
You can reset the password for all other local acounts through Cisco UCS Manager. However, you must log in to Cisco UCS Manager with an account that includes aaa or admin privileges.
