Goal

 Know how to reset CP3260 ILOM password when previous one is lost.

Solution

There are TWO possible situation:

1. ILOM password is still known/available (could access ILOM), only need to reset it back to the default (changeme)
2. ILOM password is NOT known/available (no access to ILOM), and need to reset the password (changeme) to set a new one

For #1, the steps are as following:

1. Log into ILOM using the existing password
2. Change directory to /SP
3. Set the parameter "reset_to_defaults" to "factory"
4. Reset SP

Example output of the above steps:

SUNSP-1B000N login: root
Password:

For #2, the steps to reset the blade password are:

1. Connect serial cable to CP3260 blade
2. Install CP3260 in CT900 chassis, and power on the blade ([clia] activate board <slot #>) if not powered up automatically
3. Watch blade boot and look for "Booting Linux in 5 seconds..."
4. At "Booting Linux in 5 seconds..." type "xyzzy".  You don't have to press "Enter"
5. You will be taken to "u-boot>" command prompt.
6. Type "setenv preserve_conf no" and press "Enter"
7. Type "setenv factory_default yes" and press "Enter"  (some blades don't have this option)
8. Type "saveenv"
9. Type "boot"  u-boot> boot
10. Wait for system to complete booting and verify you can login to the ILOM using the default username and password.  "root" and "changeme"
