How to find IP address ON HMC ports - ASMI Tip

Putting the physical control panel in manual operating mode

There are many instances , where you want to use ASMI interface to login to Hypervisor on IBM POWER systems. ASMI is a web based interface , which can be accessed through browsers like netscape or Mozilla.

The default IP address for these HMC ports are ( POWER-6):

1. 192.168.2.147 (Port-1)
2. 192.168.3.147 (Port-2)

Now the question is that if the interfaces are not originally configured with static IP addresses , then when you use "restore to factory default" option on ASMI, you will loose the connection to hypervisor. I had the same problem and no way i could connect to ASMI again.

However i soon realized that "Restore to Factory Default" option was not the problem , but it was changed IP address on HMC ports which create the problem.

Now question is how new IP addresses on HMC ports can be found? After long research i found the following tip which is to "How to find IP address on HMC ports on POWER systems".

Function 30: Service processor IP address and port location

This function displays the service processor IP address and port location. This function is available only in the manual operating mode and from power on standby.
Note: If IPv6 is displayed on the control panel, then the service processor's network ports are configured with IPv6 IP addresses. There are not enough characters on the control panel to display the entire address.

So to get to this function , you have to use increment Key to reach 30 and then press enter key to enter the function 30 and reach 00 to get IP address on HMC1 port and 01 to get IP address on HMC2 port.
