Change the ILOM IP address

From time to time I have to change the IP addresses on the ILOM (Integrated Lights Out Manager). So I decided to post my notes on how to do this and maybe someone will find it useful. There is also anther older hardware manger called ALOM (Advanced Lights Out Manager), this not the same. They both the provide console access to your server. For these don't know, console access is when you get remote access to a server, as if you where right next to it. So basically you see everything as if you where physically there. Note that this post changes the IP address for the MGT (management) port. This doesn't change the servers IP address for the OS installed on the hardware.

If this is the first time anyone has logged in then the ILOM will be set to the defaults. The default username is root and the default password is changeme.
# ssh root@server-ILOM
Are you sure you want to continue connecting (yes/no)? yes
Password:

For most severs with ILOM just put in the commands like you see below in the example. -> cd SP/network
-> set pendingipaddress=10.1.0.10
-> set pendingipgatway=0.0.0.0
-> set pendingipnetmask=255.0.0.0
-> set pendingipdiscovery=static
-> set commitpending=true

To check you work or see what your IP settings are, type ls or use the command below
You can see your IP address from any place in the ILOM by running the command below. -> show /SP/network 
To change the IP address of the chassis or CMM that hold the blade servers. Login and go to /CMM/network like in the example below and run the same commands as above. -> cd CMM/network
You can change the IP to the blades from the chassis ILOM as well. -> cd CH/BL#/SP/network

If you have any comments or questions please post them below.

  3. With a larger supply of addresses available for sale or rental, incentive for companies to convert over to the IPv6 protocol will be reduced.IP address
