Hi Marc,

Well… when you start your LPAR there’s no IP or subnet for itself, you just have a communication layer. And you can have different network masks, but USUALLY your DHCP server in on the same subnet, yes.

You can use this to build a DR on demand, creating an OVA with your IP addressing and the empty or Option21-like IBM I pre-packaged, an object storage with your latest backup and your journal receivers (something like "Recover for I" could help) and a nice script to automate the LPAR creation and restore. Easy and inexpensive DR-on-Demand solution.

FYI: Skytap uses DHCP and works pretty well. That way they can change IP addressing from their portal, without touching your LPAR.

Thanks for feedback, Diego.

Just curious: from a network perspective, on which subnet is located the dhcp server? Is there some dhcp relay running on the default gateway?
