Yes.

Yes, if you specify a bus as being shared, then you could have the IOPs
on that bus available to multiple partitions, although not concurrently.
All IOAs would switch with the IOP.

Yes, this would apply to all of your IOPs, with the exception of the
base IOP which would control the boot disk for the partition.

Consoles are not shared, each partition would need to have a console
designated.  Probably could be twinaxial or other.  I'm not sure on the
ECS side of things.

All IBM software is licensed for the entire machine at the tier level
for the entire box and can be used on all partitions.

Marty,

Hardware planning is key.  Figure out the business use for each
partition, then get together with a good hardware person.
