Changing devices

To change device data, you have to follow the same panel flow as for defining a device:

  1. Changing device and control unit definitions
  2. Changing CSS-related definitions
  3. Changing OS-related definitions

The following steps describe the panel flow and where you can change which data.

  1. On the I/O Device List, select a device or a group of devices and the Change action from the context menu (or action code  c ). HCD shows the following panel:

 Specify or revise the following values.

 Volume serial number . . . . . ______  + (for DASD)                         
                                                                             
 PPRC usage . . . . . . . . . . _  + (for DASD)

 ENTER to continue.

    Depending on whether you invoke this action for a single device or a group of devices, the line Number of devices shows how many devices are affected by the change.

  2. On the Change Device Definition panel you can change device and control unit definitions such as:
    • Serial number
    • Description
    • Volume serial number
    • PPRC usage
    • Control unit connections
  3. After pressing the Enter key, the Device / Processor Definition panel is displayed. Select a processor and press the Enter key to change the following CSS-related definitions:
    • Subchannel set ID
    • Unit address
    • Time-Out
    • STADET
    • Preferred CHPID
    • Explicit device candidate list
  4. After pressing the Enter key twice , the Define Device to Operating System Configuration panel is displayed. Select an operating system and the Select (connect/change) action from the context menu (or action code  s ) if you want to change the following OS-related definitions:
    • Parameters/Features
    • Assignments to esoterics
  5. After pressing the Enter key again, the Assign/Unassign Device to Esoteric panel is displayed. If you want to change the assignment of devices to esoterics, type over the values in the Assigned column by either Yes or No.
  6. Press the Enter key twice to return to the I/O Device List.
