Detailed below is a sample MPIF loosely coupled complex and the commands required to initialize the complex. It is assumed that the system has been generated with the MPIF function included and the appropriate address ranges have been included for the channel-to-channel (CTC) communication links.
Figure 7. Sample MPIF Loosely Coupled Complex. CTC represents channel-to-channel support.
Notes on the Sample Configuration:
Channel # | Address Range Generated | Actual Addresses Available | Device Name |
---|---|---|---|
1 | 0320-033F | 0320-0323 | $CTOCA1 |
2 | 0340-035F | 0340-0341 | $CTOCA2 |
3 | 0320-033F | 0320-0323 | $CTOCA1 |
4 | 0340-035F | 0340-0341 | $CTOCA2 |
MPIF requires a pair of addresses to define a logical path, one address for reading and one for writing. MPIF will do the pairing of addresses automatically.
