Configuring and Using the 9900 Subsystem
2105 Controller Emulation. To define a 9900 logical control unit (LCU) and the base and
alias address range that it will support, please use the following example for HCD.
Note: The following HCD steps correspond to the 2105 IOCP definition shown in Figure 4.3.
Note: The HCD PAV definitions must match the configurations in the 9900 subsystem. If not,
error messages will occur when the HOSTs are IPL’d or the devices are varied online.
1. From an ISPF/PDF primary options menu, select the HCD option to display the basic HCD
panel (see Figure 4.4). On this panel you must verify the name of the IODF or
IODF.WORK I/O definition file to be used.
2. On the basic HCD panel (see Figure 4.5), select the proper I/O definition file, and then
select option 1 to display the Define, Modify, or View Configuration Data panel.
3. On the Define, Modify, or View Configuration Data panel (see Figure 4.6), select option 4
to display the Control Unit List panel.
4. On the Control Unit List panel (see Figure 4.7), if a 2105 type of control unit already
exists, then an ‘Add like’ operation can be used by inputting an ‘A’ next to the 2105
type control unit and pressing the return key. Otherwise press F11 to add a new control
unit.
5. On the Add Control Unit panel (see Figure 4.8), input the following new information, or
edit the information if preloaded from an ‘Add like’ operation, and then press enter key:
Control unit number
Control unit type – 2105
Switch information only if a switch exists. Otherwise leave switch and ports blank.
6. On the Select Processor / Control Unit panel (see Figure 4.9), input an S next to the
PROC. ID, and then press return key.
7. On the Add Control Unit panel (see Figure 4.10), enter chpids that attach to the control
unit, the logical control unit address, the device starting address, and the number of
devices supported, and then press return key.
8. Verify that the data is correct on the Select Processor / Control Unit panel (see Figure
4.11), and then press F3.
9. On the Control Unit List panel (see Figure 4.12), add devices to the new Control Unit,
input an S next to CU 8000, and then press enter.
10. On the I/O Device List panel (see Figure 4.13), press F11 to add new devices.
11. On the Add Device panel (see Figure 4.14), enter the following, and then press return:
Device number
Number of devices
Device type: 3390, 3390B for HPAV base device, or 3390A for HPAV alias device.
12. On the Device / Processor Definition panel (see Figure 4.15), add this device to a
specific Processor/System-ID combination by inputting an S next to the Processor and
then pressing the return key.
13. On the Define Device / Processor panel, enter the values shown in Figure 4.16, and press
the return key.
