If the root password on the ILOM is currently unknown, but you have root access to the O/S installed, you can change the ILOM password back to the default “changeme”.
Follow below steps:
# which ipmitool
# /usr/sbin/ipmitool -V
ipmitool version 1.8.8
# /usr/sbin/ipmitool user set password 0x02 changeme
[or 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.
