This page provides details of what's new in HCM for z/OS V1R10.
Enhanced named view
HCM handles the display of named views in a more intuitive way. Therefore, the following information is additionally saved when creating a named view:
- List of selected objects: Objects that had been highlighted when the view was saved, will be highlighted again in the restored view.
- Zooming and scrolling: The zoom factor as well as the horizontal and vertical scroll position is saved.
- Connected objects: If you restore a named view that has been created with SHIFT+F4, you will see the currently connected objects, even if the connections changed after the view was saved.
If you selected Objects not connected to processors in the Change View Attributes dialog, not all disconnected devices and their controllers are shown, but only disconnected devices/controllers of those types that you included in that dialog.
If the Objects not connected to processors checkbox is selected, the diagram now shows the controllers of the selected controller types which are not connected to processors, while in previous releases unconnected controllers of all types had been shown without regarding the user’s controller type selection.
Using configuration packages with HCM
A configuration package is a subset of a centrally maintained master IODF which is extracted from that master IODF and distributed for activation at specified target systems. Up to now, working with configuration packages was only possible with HCD. Starting with this release of z/OS new HCM dialogs let users define, edit, transmit and delete configuration packages, corresponding to the HCD functionality.
This function is not available for z/VM.
Create and migrate I/O configuration statements
HCM implements new dialogs that let users perform the following tasks, that so far have been available in HCD only:
- Export/build IOCP input data set
- Export/build I/O configuration statements
- Import/migrate I/O configuration statements (including IOCP input data) into an IODF
Enhanced copy wizards
The Copy Channel Subsystem wizard allows you to specify an existing target CSS if it contains reserved partitions only.
The Copy Partition wizard allows you to specify an existing reserved partition as target partition.
CUADD value is shown on the Control Unit List
A new column CUADD is introduced on the Control Unit List to display the defined logical address for a control unit, where available.
New channel path type for coupling over InfiniBand
The use of InfiniBand technology is supported by a new channel path type CIB to emulate coupling connections in the Host Communication Adapter (HCA). Support is provided on type 2094, 2096 and type 2097 processors to define coupling links and STP links between CPCs.
Handling multi-user access enabled IODFs
In z/OS V1R10 HCD, when creating an IODF, you can specify a multi-user access (MUA) option so that multiple users can simultaneously update this IODF. From HCM’s IODFs and IODF Details dialogs, you can find out whether an IODF’s MUA status is enabled or disabled. However, you cannot work with MUA-enabled IODFs in HCM.
HCM support for making exported data accessible for the Tivoli Inventory database is no longer available.
