HMC : Dynamic I/O

2006-05-10 Thread Ed Micucci
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 from

: Dynamic I/O 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

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. - -teD
