The HP server must have been installed with the HP ESXi ISO -or- Updated via VMware Update Manager (VUM) with the latest vibs from vibsdepot.hp.com.
The process to configure the ILO is as follows:
1. SSH to the ESXi host
2. cd /opt/hp/tools
3. Export the current config: ./hponcfg -w /tmp/ilo_config.txt
4. Edit the above export config file (/tmp/ilo_config.txt) and change the following variables:
<IP_ADDRESS VALUE = “10.10.10.20”/>
<SUBNET_MASK VALUE = “255.255.255.0”/>
<GATEWAY_IP_ADDRESS VALUE = “10.10.10.1”/>
<DHCP_ENABLE VALUE = “N”/>
5. Flash the updated config to the ILO: ./hponcfg -f /tmp/ilo_config.txt
[Let the ILO restart]
6. You must now reset the Administrator password. Create the file: reset_admin_pw.xml with the below info and add the new password in the password section:
<ribcl VERSION="2.0">
<login USER_LOGIN="Administrator" PASSWORD="YOUR-NEW-PASSWORD">
<user_INFO MODE="write">
<mod_USER USER_LOGIN="Administrator">
<password value="newpass"/>
</mod_USER>
</user_INFO>
</login>
</ribcl>
7. Flash “reset_admin_pw.xml” to the ILO: ./hponcfg -f reset_admin_pw.xml
8. Done. You should be able to reach the ILO web management interface and login as Administrator.
