Title: Two LPARs with one head?

This is (one of ) the scenarios that CSE was designed to solve.

 

Take a look in CP Planning and Admin on setting up CSE, and there is some discussion of how to handle directory sync (either via DIRMAINT or friends, or on having separate directory areas).

 

CSE also gets you some other nifty benefits as well, although you need RSCS and PVM to take advantage of all of the possible goodies.

Subject: Two LPARs with one head?

How close can I get to running two LPARs using the same SYSRES volume? The System Config file supports multiple systems, and the checkpoint and warmstart data can be different for the two systems, and the paging and spool volumes can be specified differently for the two systems, but I can't see a way to run two separate directories. Or.... Can two systems run off the same directory? And if so, how could you put the directory online on the second system?

I want the directories to be logically the same on both systems anyway, so using the same physical directory would be fine with me... If updates could be picked up in the second system.

TCPIP can be configured using files with the system name as the file name, so there's no conflict there.

How are other sites handling running two LPARs, and how much is really "sharable" between the two? I feel like I'm just missing a couple of key pieces to get this right...
