Thanks to all that responded. Having the feature ?enable dynamic_I/O? set in the parm does not do any good. When z/VM is reactivated, it is automatically disabled because of an invalid z/VM token. This is because I maintain the I/O configuration under z/OS and the token is z/OS. From the manual:
If one operating system discovers (by checking the configuration token) that the other operating system "owns" the I/O configuration, the operating system that discovered the change will disable its own dynamic I/O support. That is, if z/OS finds a VM configuration token in the hardware system area (HSA), z/OS disables its dynamic I/O support and, thereafter, can only make changes to the software I/O configuration. If z/VM finds a z/OS configuration token, z/VM disables its dynamic I/O support and, thereafter, can make software-only changes. I deactivated and reactivated the LPAR and that still did not do any good. I think what you meant was the ?Enable New_Devices_Initialized_When_Added?. I issued a ?q new_devices? which said it was already enabled. I queried the CHPID and it said it was online but there were no devices. However, once I varied the CHPID online, all my devices appeared. One last question: How can I query which IOCDS z/VM is using: Thanks as always.

As long as DYNAMIC_I/O is enabled in SYSTEM CONFIG, CP will react to devices that come or go due to dynamic updates to the I/O subsystem. No need to send the IODF to VM since VM isn't the LPAR controlling the I/O config. (Unlike MVS, CP doesn't use an IODF to figure out what devices are available and what kind they are.)
