You can't add additional addresses, but the addresses of your FSP means that you had powered on that Power5 before you had the HMC ready, and the FSP took the default address when it can't find an HMC. You can always manually change the address of the FSP (not recommended if you have a closed network with DHCP on the HMC).

Select your range carefully as it shouldn't be part of your regular network address scheme.

Subject: HMC DHCP address range

I am in the HMC guided setup wizard. The wizard is asking "do you want to specify this HMC as a DHCP server?" The wizard says to select as a DHCP server "so that the managed systems on the network will be automatically configured and discovered by the HMC".

But the drop down list of address ranges does not include the address of my managed system, a 520 with an FSP address of The closest range in the dropdown list is -

Is there a way to add more address ranges to this drop down list? Should I change the HMC address of the 520 to be in the range of one of the existing ranges?
