How to reset HP iLO Lights-Out User and Password Settings with IPMItool

Warning:
Do NOT follow guides that suggest to make a DOS boot disk, this is over complicated.

Use the ipmitool which ships with most Unix based operating systems. I tested on SmartOS and Ubuntu Linux. Use a live boot disk if you must.

  1. Run ipmitool user list to list all users installed on the iLO.
  2. Choose a user ID from the list and run ipmitool user set password [ID].
  3. Last, make sure the user is enabled with ipmitool user enable [ID].

Here is a complete set of commands I used to reset user ID 6:

[root@1c-c1-de-f0-ad-36 /opt]# ipmitool user list
ID  Name             Callin  Link Auth  IPMI Msg   Channel Priv Limit
2   ROUSER           true    false      false      Unknown (0x00)
3   USERID           true    false      false      Unknown (0x00)
4   OEM              true    false      false      Unknown (0x00)
5   Operator         true    false      false      Unknown (0x00)
6   admin            true    false      false      Unknown (0x00)
... truncated ...
15  admin            true    false      false      Unknown (0x00)
16  OEM              true    false      false      Unknown (0x00)

[root@1c-c1-de-f0-ad-36 /opt]# ipmitool user set password 6 mynew-password

[root@1c-c1-de-f0-ad-36 /opt]# ipmitool user enable 6

Next I logged into the web GUI and cleaned up this crazy list of users. You may also need to change the privileges on a user ID to grant admin level access. Run ipmitool user for a list of possible sub-commands.

After I finished poking around with the web GUI, I decided to learn a bit more about IPMI and the ipmitool command.

I figured out how to get sensor information over the LAN using this command:

sudo ipmitool -I lan -H guy-ilo.foxhop.net -U admin sensor

I was even able to log into the server OS via Serial-over-LAN (SOL) using this command:

sudo ipmitool -I lanplus -H guy-ilo.foxhop.net -U admin sol activate

Serial-over-LAN completely resolves the need for a complicated JAVA/KVM (keyboard video mouse) setup, I was able to reboot the server and watch the machine POST over the serial connection! Now you don't need to shell out $229+ on an Advanced 1 yr single server Licence for HP Lights-Out 100i (LO100i)!

I uploaded a video showing Serial-Over-LAN with IPMItools to an HP Proliant DL160 G6 running SmartOS.

Update:

Documenting a few other useful commands for myself here.

Power on and off the server chassis:

sudo ipmitool -I lan -H guy-ilo.foxhop.net -U admin chassis power status
sudo ipmitool -I lan -H guy-ilo.foxhop.net -U admin chassis power on
sudo ipmitool -I lan -H guy-ilo.foxhop.net -U admin chassis power soft
sudo ipmitool -I lan -H guy-ilo.foxhop.net -U admin chassis power off
sudo ipmitool -I lan -H guy-ilo.foxhop.net -U admin chassis power cycle

Update:

Apparently after you know the ILO username and password you may also use SSH to connect and manage the server:

ssh admin@guy-ilo.foxhop.net
admin@guile-ilo.foxhop.net's password:

You can even trigger the server OS to stop change run levels or mess with chassis power for more extreme measures.

/./system1/-> stop
System1 stopped.

Update:

I run FreeNAS on an HP DL180 G6 and just replaced my p410 controller with an LSI SAS9220-8i (IBM M1015) flashed to IT mode. The stock cables are long enough. I did not have issues with fans running at high RPM.

(I did the same replacement on an HP DL160 G6 running SmartOS and it didn't have a high fan RPM issues either)
