Scenario II – Defining a CTC connection

In this scenario we create CTC connections involving three processors routed through a switch. We assume that the following processors and unconnected CHPIDs exist:

• SMP Processor PROC1 (type 2064 with partitions LPAR11 and LPAR12) with CHPID:
  • 20 CTC SHR (LPAR11 in the access list)
• SMP Processor PROC2 (type 2064 with partitions LPAR21 and LPAR22) with CHPIDs:
  • 20 CTC SHR (both partitions in the access list)
  • 21 CNC SHR (both partitions in the access list)
• XMP processor PROC3 (with LCSS 0 and partition LPAR31) with CHPID:
  • 21 CNC SHR (LPAR31 in the access list)

We also assume that an operating system exists (OS1 of type MVS) and that an ESCON Director 01 (9032-5) exists with ports E0-E3 free.

We create four CTC connections:

PROC1.20 CTC to PROC2.21 CNC
PROC2.20 CTC to PROC2.21 CNC
PROC1.20 CTC to PROC3.0.21 CNC
PROC2.20 CTC to PROC3.0.21 CNC
