Thanks all, I appreciate all the info.
PS: Roger, I'm a "hand-coder" too and didn't care much for the HCM app. :)

Mike,
I use XEDIT to maintain the IOCP file. There is a HCM application
distributed with the z/VM HCD, but I find it difficult to use.
I then run the following commands from userid CBDIODS.
CBDSIODF to create a HCD skeleton file.
CBDSMIGR to create a work IODF by loading the IOCP source into the skeleton
file.
CBDSPROD to create a production IODF file, filetype PRODIODF.
CBDSIOCP write the IOCDS.
CBDSACT to active the IOCDS without a POR.
The PRODIODF file needs to be copied to all CP parm disks.
"IODF *" is specified in the SYSTEM CONFIG on the CP parm disk.

z/OS is not on the same box, this particular z/10 only houses VM and TPF
LPARs.
We have CBDIODSP and HCM all set up and configured so the z/OS guys COULD
use the VM-based HCM to build their files. I'm just still unclear how CP
picks up the changes in the new IOCDS and makes them available dynamically
on a running z/VM system. Apparently, on z/OS systems they "activate" a new
IODF - but I don't see anything like that on z/VM except the SET IOCDS
_Active command (which I don't believe, based on the documentation, will
alter the running CP - please correct me if I'm mistaken). :)

Is z/OS in anot her LPAR on the same box?
If so, it's easiest just to let them do it and VM will just see the changes.

Subject: [IBMVM] Dynamic Activation of New IODF
Hi Folks,
For many (many) years, when it comes to managing the IOCDS I simply
hand-create an IOCP file, use IOCP with WRTAx to store it, and do a POR to
load it. If the changes are needed immediately, I use CP commands to
manually define the new hardware.
Our z/OS guys want to manage the IOCDS and be able to dynamically activate
an entirely new IODF file (created either on their system or using VM's
HCM/HCD). I'm unclear as to when/how the changed IODF file becomes
dynamically available to the running z/VM system.& nbsp; Let's say I store
the new IODF using IOCP with WRTAx to store it, and then execute SET
IOCDS_Active to mark it as the active IOCDS - according to the doc for SET
IOCDS_Active this simply marks the IOCDS as active for the NEXT POR (and
write-protects it) - but it doesn't look like the changes in the new IOCDS
are reflected to the running z/VM system until a POR occurs.
What am I missing here? Is it even possible to store a new IOCDS, mark it
as active for the next POR AND have CP add/change/delete IO definitions by
comparing the prior IOCDS with the newly activated one?
-Mike
