The root password on the ILOM is currently unknown. I have root access to the O/S installed on the platform and want to change the ILOM password back to the default changeme.

Fix

Complete the following steps:

# which ipmitool

/usr/sbin/ipmitool



# /usr/sbin/ipmitool -V

ipmitool version 1.8.8



# /usr/sbin/ipmitool user set password 0x02 changeme



You can also use the raw format 



# /usr/sbin/ipmitool raw 0x06 0x47 0x02 0x02 0x63 0x68 0x61 0x6e 0x67 0x65 0x6d 0x65 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00

There will be no confirmation after running the ipmitool command, however the ILOM root password will be changed to changeme.

Notes
This solution is from the IPMI specification. This is the "set user password" command in raw format.
Since the KCS interface between the host and it's service processor does not require authentication, you can set any user's password from the main host itself. This is not possible from an ILOM out of band connection.

This has been tested and verified on ILOM 2.x and 3.x.
This process has been successfully tested on several x64 product lines so may be successful on platforms not identified in this document.
