LOM password reset on 5600 and 12400 appliances



Can you please suggest if there is an option for LOM password reset? I hound instructions for setting IP, how about resetting LOM Lights Out Management password? 






sk97849 - Configuring IP Address for LOM card on 21400 appliance through the System Console

sk94670 - Setting Lights Out Management (LOM) IP address from SecurePlatform OS on Power-1 appliance...


  1. At the system console port, load the IPMI drivers into Linux memory: 

    [Expert@HostName]# /etc/init.d/ipmi start 

    Should get:
    Starting ipmi drivers: [ OK ] 

    Note: It takes around 20 seconds to load the drivers. 

  2. Check if LOM LAN factory default settings are correct. The bold IP addresses indicated by "<----" are the ones that will be modified. 

    [Expert@HostName]# ipmitool lan print 1

                            :     o=OPERATOR
                            :     a=ADMIN
                            :     O=OEM
  3. Set the timeout value for the LOM console switch to 59 minutes:

Just to add into it. If you perform a full reset on LOM on remote Firewall, it will make it inaccessible unless you have 192.168.X.X subnet to talk to it. However, the work around is do " ipmitool lan print 1" or " ipmitool lan print 8" and check the exisiting IP Address and Default Gateway details. Once you have the details, you can perform full reset using  "ipmitool raw 0x2e 0x02"  under the expertmode in CLI and then assign LOM same IP Address using "lomipset <LOM_IP_ADDRESS> <LOM_NETMASK> <LOM_DEFAULT_GW_ADDRESS>” command under the expertmode and access the LOM using a Web browser, login using defaul login details, and go through the setup process.

Hello Sergej

Old thread but I just came across this when trying to kick a couple of LOM cards into action. Symptom, LOM MACs not seen on switchport (hence LOMs unreachable).

I tried ipmitool raw 0x2e 0x02 but it didn't do anything. Found the command below on a Nutanix site, tried it and worked perfectly (once cards reset, MACs seen on switchports and LOMs reachable, with configuration retained):

# ipmitool mc reset cold

Maybe a good one to update sk127573 with before doing full factory reset
