SysAdmin’s Diary

This is almost similar with my previous post on how to reset Administrator’s password from OS by using hponcfg. This time, I want to reset the iLO network information.

Problem Statement
I’m unable to access iLO from this server. Since I can’t easily go to BIOS to get the network information, I need to use hponcfg which can be done from OS level.

Info
Machine: HP ProLiant BL20p G3
OS: Red Hat Enteprise Linux 3
Kernel: 2.4.21-20.ELsmp

Step-by-step Process

1. Get current network information,
   code

   1. [01:16 PM]root@cliskmcp01:root > hponcfg -f /home/jmirwan/iLOscript/Get_Network.xml
   2. Firmware Revision = 1.82 Device type = iLO Driver name = cpqci
   3. <GET_NETWORK_SETTINGS>
   4.     <ENABLE_NIC VALUE="Y"/>
   5.     <SPEED_AUTOSELECT VALUE="Y"/>
   6.     <NIC_SPEED VALUE="10"/>
   7.     <FULL_DUPLEX VALUE="N"/>
   8.     <DHCP_ENABLE VALUE="N"/>
   9.     <ENCLOSURE_IP_ENABLE VALUE="N"/>
   10.     <DHCP_GATEWAY VALUE="Y"/>
   11.     <DHCP_DNS_SERVER VALUE="Y"/>
   12.     <DHCP_WINS_SERVER VALUE="Y"/>
   13.     <DHCP_STATIC_ROUTE VALUE="Y"/>
   14.     <DHCP_DOMAIN_NAME VALUE="Y"/>
   15.     <REG_WINS_SERVER VALUE="Y"/>
   16.     <REG_DDNS_SERVER VALUE="Y"/>
   17.     <PING_GATEWAY VALUE="N"/>
   18.     <MAC_ADDRESS VALUE="00:15:60:0d:73:20"/>
   19.     <IP_ADDRESS VALUE="172.21.21.102"/>
   20.     <SUBNET_MASK VALUE="255.255.255.0"/>
   21.     <GATEWAY_IP_ADDRESS VALUE="172.21.20.1"/>
   22.     <DNS_NAME VALUE="ILOT00CMKT25H"/>
   23.     <DOMAIN_NAME VALUE=""/>
   24.     <PRIM_DNS_SERVER VALUE="0.0.0.0"/>
   25.     <SEC_DNS_SERVER VALUE="0.0.0.0"/>
   26.     <TER_DNS_SERVER VALUE="0.0.0.0"/>
   27.     <PRIM_WINS_SERVER VALUE="0.0.0.0"/>
   28.     <SEC_WINS_SERVER VALUE="0.0.0.0"/>
   29.     <STATIC_ROUTE_1 DEST="0.0.0.0"
   30.                     GATEWAY="0.0.0.0"/>
   31.     <STATIC_ROUTE_2 DEST="0.0.0.0"
   32.                     GATEWAY="0.0.0.0"/>
   33.     <STATIC_ROUTE_3 DEST="0.0.0.0"
   34.                     GATEWAY="0.0.0.0"/>
   35. </GET_NETWORK_SETTINGS>
   36. Script succeeded

   In this situation, I notice the gateway value is incorrect. I want to change it to 172.21.21.1

2. So, I write a simple script to change the gateway value
   code

   < view plain text >

   1. [01:34 PM]root@cliskmcp01:root > cat Set_iLO_Gateway.xml
   2. <RIBCL VERSION="2.0">
   3.    <LOGIN USER_LOGIN="adminname" PASSWORD="password">
   4.       <RIB_INFO MODE="write">
   5.         <MOD_NETWORK_SETTINGS>
   6.           <GATEWAY_IP_ADDRESS VALUE="172.21.21.1"/>
   7.         </MOD_NETWORK_SETTINGS>
   8.       </RIB_INFO>
   9.    </LOGIN>
   10. </RIBCL>
3. Run the script to reset the gateway,
   code

   < view plain text >

   1. [01:16 PM]root@cliskmcp01:root > hponcfg -f Set_iLO_Gateway.xml
   2. Firmware Revision = 1.82 Device type = iLO Driver name = cpqci
   3. Script succeeded

   Done! I’m now able to access iLO :)
