Chapter 6. Operational details 63
An IODF is still required within a z/OS system, but the HCD input to generate it does not need
to define control unit details. That is, a simple device definition (device number, type, optional
features) is all that is required. The z/OS dynamic I/O redefinition capability is not available.
You can perform
software dynamic configuration changes via z/OS Hardware Configuration
Definition (HCD) dialogs or the z/OS ACTIVATE
command, provided the affected devices are
included in the FLEX-ES definition files.
In response to a z/OS d ios,config(all)
