We want to turn on the Allow dynamic changes to the channel subsystem
input/output (I/O) definition switch on the HMC. But this will require
storage, and I can not find reference as to how much. We currently have all
available storage tied up among our LPARs. So I must steal some storage

It depends on the processor type you have and whether you have FICON, or
not.
The z/990 tends towards a GIG for HSA, and you need at least a 50%
cushion.
But, I would plan for twice as much as you are currently using.
You can display the memory usage through the HMC (I forget how

We have NO storage available for this. I will have to steal some from a
test LPAR. So I'm looking for the minimal amount needed. We're running a
z890.

Look at the SAPR Guide for z/890.
I have only looked at the ones for the z/900 z/990.
They both have an HSA planning table.
I assume the z/890 has one, as well.
IIRC, SAPR - System Assurance Planning Reference.
