Preparing configuration definition
The customer is responsible for preparing a definition of the I/O configuration for the
new processor. You should use the PCHID report from the Order Process
Configurator as a guide for planning and defining the new configuration. Depending
on the current operating environment there may be several methods for
accomplishing this.
z/VM
If you use HCM and HCD, develop the configuration using HCM and HCD.
Otherwise, develop the IOCP statements necessary to define your configuration and
use the level of the ICP IOCP program that supports the new processor to verify the
input statements. You do not need to initially assign PCHID values to the channel
paths in your configuration. You can use the CHPID Mapping Tool, available from
Resource Link, to aid you in assigning PCHIDs to CHPIDs. HCM and HCD users
must build an IOCP input data set from a validated work IODF and use this as input
to the CHPID Mapping Tool. The CHPID Mapping Tool updates the IOCP input and
assigns PCHIDs to the CHPIDs.
Note: An IOCP input file that was created by HCM and HCD without PCHIDs must
If you are installing a new processor, transfer the IOCP statements for your
configuration to a diskette. If necessary, the IOCP input file can be compressed
using a zip-compatible program. When the new system arrives, give the diskette
containing the IOCP input statements to the install team.
If you are installing a new processor, instead of using a diskette you can remotely
write the IOCDS from an HCD that is running on an installed CPC in the same
HMC cluster. Inform the install team that plans are in place to use the "Build and
manage S/390 microprocessor IOCDSs" option in HCD to write the IOCDS.

added to the file by the CHPID Mapping Tool. An IOCDS can then be written
from a production IODF or IOCP statements can be built for the install
