Oh, Doh! That is just what I need. Thanks so much, Marcy. Guess my googling skills are on the fritz today. Nothing I found mentioned either of those commands.

Since I'm messing with a production system, I don't want to screw around and do something wrong. I have an LPAR on a z15 that is running Ubuntu 18.04 native. It has 768G of memory with 256G in reserve. I need to turn on some of that 256G and have the Ubuntu system use it. Under z/VM, its one command and you are done...... In this environment, I have no idea how to: 1. Get some of the 256G released from reserve 2. Get Ubuntu to use it I'm sure that this is something that many of you have done before, so, please, help. Point me to a doc or something that describes the process. The system is running KVM and openstack, and there are nearly 100 servers running on it. So, I can't afford to reboot to turn on the memory.
