Changing processors
You can change the following data of the processor:
- Type
- Model
- Configuration Mode
- Serial Number
- Description
- Network name
- CPC name
- Local system name
- On the Processor List, select the
processor and apply the Change action
from the context menu (or action code c ). The Change Processor Definition dialog is displayed.

- To change the processor type, or model, overtype the old processor
type, or model values, and press the Enter key. To change the support
level for the same processor type, move the cursor to the Support
level line and press the Enter key. If you have installed a new processor
type or model, or a new processor support level, you need to upgrade
the processor definition within HCD. No dynamic change is possible.
HCD selects the proper configuration rules that are dependent on the
processor type, and support level, and generates the correct input
for the IOCDS download process.
Note:
If the
processor change leads to error message CBDA102I, make sure that the
new processor type/model supports the same configuration rules as
the old processor type, for example, that the same channel path types
are supported. Subsequent messages indicate an invalid support level.
You first have to update your configuration according to the new processor
type/model before you can change the processor.
- If more than one support level is available for the processor
type, the Available Support Levels panel is displayed where you can
select the correct support level for your processor.
Note:
On the Available Support Levels panel you can retrieve an
explanation of the processor support level for System z processors:
Position the cursor on the processor support level description and
press the F1 key to get an enumeration of functions provided by this
support level.
- The Update Channel Path Identifiers panel is displayed. This
panel shows the old channel path definitions, which you can change
according to your new processor configuration.
*--------------------- Update Channel Path Identifiers ----------------------*
| Row 1 of 24 |
| Command ===> __________________________________________ Scroll ===> CSR |
| |
| Specify any changes to the channel path identifiers in the list below. |
| |
| Processor ID . . . . . . : PROC1 |
| Channel Subsystem ID . . : 0 |
| |
| CHPID Type Side Until CHPID New CHPID + |
| 24 OSD __ 24 |
| 25 OSC __ 25 |

| 2A FC __ 2A |
| 2B FC __ 2B |
| 2C FCP __ 2C |
*----------------------------------------------------------------------------*
The
column New CHPID shows the channel path IDs to which the values of
column CHPID are mapped by default.
- You can overtype the values of the column New CHPID. Leave the
column Until CHPID blank. Press the Enter key to move the old channel
path IDs to the new channel path IDs.
- If you enter a value in the column Until CHPID, you move all defined
CHPIDs in the range defined by the channel paths specified in the
CHPID and Until CHPID column to the new range that starts with the
value in the New CHPID column. If the values for the CHPID column
have a 'gap', the 'gap' is also reflected in the New CHPID column
range. When you entered a value in the Until CHPID column, press the
Enter key. The Update Channel Path Identifiers panel is redisplayed
where the new range is resolved in the New CHPID. The Until CHPID
column is shown as blank. To process the updates, press the Enter
key again.
- The source and target CHPIDs of a CIB coupling connection
are each given the local system name of the processor to which they
will connect. This is automatically done by HCD at the moment when
the IOCP input file is built. Therefore, you should be aware of the
consequences of changing the local system name. Consider, for example,
a scenario, where during a processor upgrade,
you want to adapt an existing local system name to match with a new
CPC name. Then the I/O configuration of the target processor of an
existing CIB connection also changes and requires a dynamic activate
or a POR (in case of a stand-alone CF CPC) to re-establish the CF
links. Therefore, HCD issues the CBDG400I warning message whenever
a user changes a processor’s local system name.
Note:
If the processor upgrade changed the SYSTEM value
of the corresponding IOCP configuration, it may not be possible to
do an IOCDS download. It is only possible to perform an IOCDS download
for specific processor types because IOCP validates the generated
IOCP statements according to the configuration rules of the executing
processor. See Supported Hardware Report for the processor type which
allows you to download an IOCDS in preparation for a processor upgrade.
If
a processor type change leads to change of the SYSTEM value of the
corresponding IOCP configuration, see Build an IOCDS and Build System z cluster IOCDSs.
Changing the processor ID
To change the ID of a processor, perform the following steps:
- On the Processor List, select the processor and the Repeat (copy) processor configurations action
from the context menu (or action code r ). The Identify
Target IODF panel is displayed.
- Press the Enter key to accept the default target IODF name, that
is the IODF you are currently working with. The Repeat Processor
panel is displayed.

- Specify the new identifier for the processor and press the Enter
key. HCD creates a new processor with the same characteristics and
connections as the old one.
- On the resulting Processor List, delete the old processor by selecting
the processor and selecting the Delete action
from the context menu (or action code d ). HCD displays
a confirmation panel before showing the updated Processor List.
