I would recommend creating a new 64-bit controller. It will require more disk space and add a running Linux, but this approach is less complex, and the cloning script will work unmodified. Rather than naming the controller LINUX00 as described in the book, I set up a system with two controllers named SLES9 and SLES9X. Of course if you want a 31-bit system you clone from SLES9 and for a 64-bit system from SLES9X. The target virtual machines can be interchangable. > 2) What would be a rough procedure to apply service (e.g. a service pack, > kernel patch) to > a) the controller image Just apply it. > b) the golden-image and Shut down the controller, IPL the golden image and apply it.

The obvious choice is to apply the patch to each of the cloned machines. Of course there other ways to avoid having to do this. One way is to shut down a back level machine, clone a new updated machine and copy all configuration data to the new machine. This was one of the motivations of having rsync back up all /etc/ file systems of the cloned machines. But we never got to testing the various types of servers. And of course other files/directories would have to be backed up. But it is a good way to separate your OS from your applications. Also, there is the possibility of a shared /usr/ perhaps with DCSSs and XIP2, but that is a whole different book. > 3) Our dasd doesn't support flashcopy, so in the cloning process, the > dasdfmt+dd takes about 30 minutes for the combined dasd 102 and 100.

Yes, but under the premise of "keep things as simple as simple as possible" we avoided DDR because it would require a new service machine.
