Defining OS-related definitions for a device
- After pressing the Enter key on the Define Device / Processor panel,
the Device / Processor Definition panel is displayed
again. Select another processor or press the Enter key again to display
the Define Device to Operating System Configuration panel
that shows all the defined OS configurations.
┌─────────── Define Device to Operating System Configuration ───────────┐ │ Row 1 of 2 │ │ │ │ Select OSs to connect or disconnect devices, then press Enter. │ │ │ │ Device number . : 01E1 Number of devices : 8 │ │ Device type . . : 3390A │ │ │ │ / Config.

As described in Defining the subchannel set for a device, starting with 2094 (z9 EC) processors, you can place PAV alias devices (types 3380A and 3390A) into SS 1.
If you define a PAV alias device, as shown in our example from Figure 3, HCD displays the Specify Subchannel Set ID panel that asks for the subchannel set where you want to place the device. The default depends on the value given for the corresponding CSS definition.
Figure 1. Specify Subchannel Set ID┌─────────────── Specify Subchannel Set ID ─────────────────────────┐ │ │ │ │ │ Specify the ID of the subchannel set into which devices are │ │ placed, then press Enter. │ │ │ │ Configuration ID . : OPSYS01 │ │ Device number . . : 01E1 Number of devices : 8 │ │ Device type . . . : 3390A │ │ │ │ Subchannel Set ID 1 + │ │ │ │ F1=Help F2=Split F3=Exit F4=Prompt F5=Reset F9=Swap │ │ F12=Cancel │ └───────────────────────────────────────────────────────────────────┘ - Pressing Enter on the dialog from Figure 1 brings
you to the following panel where you can now define the data about
device parameters and features that are required by the operating
system configuration. The Parameter/Feature fields vary depending on the I/O device type and operating system type.
┌──────────────────── Define Device Parameters / Features ───────────────────────┐ │ Row 1 of 4 │ │ │ │ Specify or revise the values below. │ │ │ │ Configuration ID . : OPSYS01 MVS or z/OS operating system │ │ Device number . . : 01E1 Number of devices : 8 │ │ Device type . . . : 3390A │ │ │ │ Parameter/ │ │ Feature Value + R Description │ │ WLMPAV Yes Device supports work load manager │ │ ***************************** BOTTOM OF DATA *************************** │ └────────────────────────────────────────────────────────────────────────────────┘A plus sign (+) in the Value column indicates that you may use F4=Prompt to get a list of possible values for the parameter/feature in the same row. Note that not all parameters are promptable.
A Y in the R column indicates that a value for the parameter/feature in the same row is required.
You accomplish the change by accepting the default values or by changing the Value entries and pressing the Enter key. The default values are set in the UIM for the device type. For parameters you can specify different default values via the OS_PARM_DEFAULT keyword in the HCD profile.
- For eligible devices, after you have defined the device parameter
and feature data and pressed the Enter key, HCD displays the Assign/Unassign
Device to Esoteric panel.
┌──────────────────── Assign/Unassign Device to Esoteric ─────────────────────┐ │ Row 1 of 2 │ │ │ │ Specify Yes to assign or No to unassign. To view devices already │ │ assigned to esoteric, select and press Enter. │ │ │ │ Configuration ID : OPSYS01 MVS or z/OS operating system │ │ Device number . : 01E1 Number of devices : 8 │ │ Device type . . : 3390A Generic . . . . . : 3390A │ │ │ │ / EDT.Esoteric Assigned Starting Number Number of Devices │ │ _ A1.ES001 No ____ ____ │ │ _ A2.ES002 No ____ ____ │ │ ***************************** BOTTOM OF DATA ****************************** │ └─────────────────────────────────────────────────────────────────────────────┘ - On the Assign/Unassign Devices to Esoterics panel, overwrite the
values in the Assigned column to assign (Yes)
or unassign (No) devices to the selected esoterics.
If you do not want to assign a complete group of devices, you can limit the range by specifying a starting number and the number of devices. If you omit the number of devices, 1 is assumed.
