appendix assume a login by the root user.

If no one can log into the SP manager, you can perform the following procedure to reset the root or

admin user’s password. This procedure would be needed, for example, if an attempt to log into the

console as root brings up the following message:

1 FROM FOR root, User not known to the underlying

authentication module

To recover from login failure:

1. Make a terminal connection to the SP manager.

2. Turn power off and then on to physically reboot the SP manager.

3. When prompted, hit any key to interrupt the boot and enter U

-Boot monitor mode.

See To boot in U-Boot monitor mode: on page 203. The U

-Boot monitor prompt appears as

shown in the following screen example.

4. Boot in single

-user mode.

5. When single user mode comes up, use the passwd command to change the root or admin

user’s password.

The following screen example shows changing the admin user’s password.

6. Restart the SP manager to return to multiuser mode.

The root or admin user should now be able to log in with the new password.

[root@MergePoint5224 root]# reboot
