This Technote contains a diagram showing suggested steps to define a new z990 or z890 I/O configuration.
Note that there is no requirement to use CMT; you can assign CHPIDs to PCHIDs directly in an IOCP source or through HCD. However, this is a very cumbersome process for larger configurations. If you choose to do manual assignment of CHPIDs to PCHIDs (using HCD or IOCP), it is your responsibility to distribute CHPIDs among the physical channel card ports (PCHIDs) for availability and/or performance. The objective of CMT is to assist in performing these tasks.
The following diagram shows the steps to define a new z990 or z890 I/O configuration.
