On most z machines, you have to enable the system for Dynamic I/O through the Security Function on the HMC. I am not sure how to do that on a z800 but that is one thing I would check. You also need to make sure that your SYSTEM CONFIG includes SET_DYNamic in the Features Enable section. Another thing to check is whether you have DYNamic_I/O in the Features Enable section. If you do, CP will turn on Dynamic I/O during initialization to verify that the security is set correctly at the hardware. You should be able to look at the OPERATOR console log from the IPL and see whether the messages show that Dynamic is available.
