New function for Hardware Configuration Definition (HCD), Hardware Configuration Manager (HCM), and both are available in V2R1.
HCD/HCM provide the following enhancements of the I/O autoconfiguration function:
You can use a new HMC-wide activate function of HCD to remotely distribute and activate a new production IODF from a single managing z/OS® system on all target systems of CPCs that are configured in the Hardware Management Console (HMC) and that are defined in a specified TCP/IP connection table.
Start this function from the System z Cluster List using action Work with CPC images introduced in z/OS V1R13. The upcoming CPC Image List now displays the activation status of the connected z/OS and z/VM® systems. It also provides new actions to activate the accessed production IODF for hardware, software changes, or both at the selected z/OS or z/VM system. The new production IODF is sent to the target system if necessary. You can remotely issue any operational commands that are required for the activation. The messages that result from the activation or from other system commands are displayed in a message list.
Validation enhancement | Description |
---|---|
A new warning message is issued when a CF CIB connection changes due to connectivity updates. | HCD issues a new warning message CBDG422I, when users add or delete a CSS to/from a CIB CHPID that involves a change of the coupling facility connection, affecting the definition of the connected processor. This message informs the user about the change and a potentially required dynamic activation of the target processor. |
Existing warning message CBDA845I is also issued for the ACTIVATE SOFT system command. | For users of the HCD Activate … dialogs, when required, HCD issues a warning message, CBDA845I, when users specify an ACTIVATE software only request without hardware validation because this does not process involved changes to coupling facility control units and devices for the software. This message is now also issued, when users specify an ACTIVATE SOFT system command without establishing hardware validation. |
