How to get or set iLO details from Linux and Windows (when you lost iLO access)

As an sysadmin, its always headache to deal with remote systems as rely on remote consoles (HP iLO, Dell iDRAC etc) for servers to access in case there is an issue on server access. And because of that its mandatory to keep remote console connection up and accessible all the time.

Here I am explaining simple method to get HP iLO information or set iLO information from your operating system (you might found this already in another portals but adding in my own collection)

We have scenarios as below,

  • VLAN migration or VLAN changes and iLO is not reachable any more
  • Someone accedently changed iLO network details and iLO is not reachable any more
  • Gateway changed for the VLAN but missed to update in iLO network details

All above cases we need to access and configure this iLO network details from operating system as we dont have iLO connection in hand.

What tool we are going to use ?

We have a great tool from HP, called hponcfg (read hponcfg docs for more details) by which you can automate most of your iLO configuration tasks.

(Also read about HPREST)

  • Download hponcfg package from here : hponcfg (download for windows from same place)
  • Install the package
rpm -Uvh hponcfg-4.3.1-0.x86_64.rpm

How to get current details from iLO ?

Once you installed hponcfg, its straight forward; just run the command with an output filename

[[email protected] ~]# hponcfg -w myilo.xml
HP Lights-Out Online Configuration utility
Version 4.3.1 Date 05/02/2014 (c) Hewlett-Packard Company, 2014
Firmware Revision = 2.53 Device type = iLO 4 Driver name = hpilo
Management Processor configuration is successfully written to file "myilo.xml"

Windows :

C:\Program Files\HP\hponcfg>hponcfg /w myilo.xml

How to configure new IP/Mask on iLO ?

To configure the IP/Mask details, we need to prepare the xml file with those information. Sample file below

cat >myserver-ilo-config.xml
<RIBCL VERSION="2.0">
 <LOGIN USER_LOGIN="user" PASSWORD="password">
 <RIB_INFO MODE="WRITE" >
 <MOD_NETWORK_SETTINGS>
 <IP_ADDRESS VALUE = "10.1.10.10"/>
 <SUBNET_MASK VALUE = "255.255.255.0"/>
 <GATEWAY_IP_ADDRESS VALUE = "10.1.10.1"/>
 <PRIM_DNS_SERVER value = "10.1.20.1"/>
 <DHCP_ENABLE VALUE = "N"/>
 </MOD_NETWORK_SETTINGS>
 </RIB_INFO>
 </LOGIN>
 </RIBCL>

Please note, the USER_LOGIN and PASSWORD tags are required but can be any value.

Execute the configuration as below with our xml file.

[[email protected] ~]# hponcfg -f cn1-ilo-config.xml
HP Lights-Out Online Configuration utility
Version 4.3.1 Date 05/02/2014 (c) Hewlett-Packard Company, 2014
Firmware Revision = 2.53 Device type = iLO 4 Driver name = hpilo
<INFORM> DHCP is currently disabled, enable DHCP to use any DHCP setting.</INFORM>
<INFORM>Integrated Lights-Out will reset at the end of the script.</INFORM>

Please wait while the firmware is reset. This might take a minute
Script succeeded

Windows

C:\Program Files\HP\hponcfg>hponcfg /f cn1-ilo-config.xml

That’s it; you have the iLO set with new IP/Mask/Gateway and just try to access it.

 

Note : If you have already access to this iLO, you can do it directly using GUI or via CLI as below

Change the IP

set /map1/enetport1/lanendpt1/ipendpt1 IPv4Address=<ilo IP> SubnetMask=<ilo subnet mask>

Change gateway IP

set /map1/gateway1 AccessInfo=<iLO gateway>
