Defining connections to switches

You can connect the following objects to a switch starting from the Switch List:

• Channel paths
• Control Units
• Other switches

You can also define connections from the objects to the switch when defining the object themselves. See How to define, modify, or view a configuration for a description how to define the objects.

Connecting a channel path

The following procedure describes how to define a connection between a channel path and a switch starting from the Switch List.

1. On the Switch List, select the switch and the Work with ports action from the context menu (or action code  p ). The Port List is displayed.

   Ports which show value Y in column O indicate that they are occupied by a processor, control unit or switch that is not defined in the accessed IODF.

2. Select a port and the Connect to channel path action from the context menu (or action code  p ).

   Occupied ports cannot be connected. However, you may change the Occupied status of a port by overwriting the Occupied indicator.

   On the resulting Connect to Channel Path panel specify the target processor ID and channel path ID.

   *--------- Connect to Channel Path ---------*
   |                                           |
   |                                           |
   | Specify the following values.             |
   |                                           |
   | Switch ID  : 99  Port . . . : C4          |

   *-------------------------------------------*

   Note:

   If you selected a spanned physical channel path as connection target, HCD connects the port to all of the channel's instances across all channel subsystems. You can see the result of your connection action in the Port List (Figure 80).

Connecting a control unit

The following procedure describes how to define a connection between a control unit and a switch starting from the Switch List.

1. On the Switch List, select the switch and the Work with ports from the context menu (or action code  p ). The Port List is displayed (see Figure 80).
2. Select a port and the Connect to control unit action from the context menu (or action code  u ).

   *-------------------------- Connect to Control Unit --------------------------*
   |                                                                             |
   |                                                                             |
   | Specify the following values.                                               |
   |                                                                             |
   | Switch ID  . . . . : 99  Port . . . . . . . : C4                            |
   |                                                                             |
   | Control unit numbers . . 00E1  ____  ____  ____  ____  ____  ____  ____  +  |
   |                                                                             |
   |                                                                             |
   |  F1=Help     F2=Split    F3=Exit     F4=Prompt   F5=Reset    F9=Swap        |
   | F12=Cancel                                                                  |
   *-----------------------------------------------------------------------------*
   
   

   You can enter up to eight control unit numbers each time the panel is displayed.

3. Repeat defining connections for all control units connected to the switch.

Connecting another switch

The following procedure describes how to define a connection between a switch and another switch.

1. On the Switch List, select the switch and the Work with ports action from the context menu (or action code  p ). The Port List is displayed (see Figure 80).
2. Select a port and the Connect to switch action from the context menu (or action code  w ).

   *--------- Connect to Switch ----------*
   |                                      |
   |                                      |
   | Specify the following values.        |
   |                                      |
   | Switch ID  : 99  Port . . . : C4     |
   |                                      |
   | Switch ID  . . . . . 98  +           |
   | Port . . . . . . . . C1  +           |
   |                                      |
   |  F1=Help     F2=Split    F3=Exit     |
   |  F4=Prompt   F5=Reset    F9=Swap     |
   | F12=Cancel                           |
   *--------------------------------------*
   
   

3. Repeat defining connections for all other switches connected to the selected switch.
