Well.....

You need to do the ACTIOCDS so that the next time you perform a POR the
system will use an IOCDS that matches your new IODF.

ACTIOCDS does not update the HSA on the system.  It tells the system which
IOCDS to use for POR.

To make the HSA be in sync with the software on all MVS LPARs, you need to
do a HW and SW activate on one LPAR and a SW only activate on the other LPARs.
