-t"'--- ., ,."...." Real I/O Configuration File Example of Coding the Real I/O Configuration File (DMKRIO) In this example, macros are coded to support the following real devices:
1 2540 Card Reader/Punch
1 3505 Card Reader
1 3525 Card Punch
2 1403 Printers with the Universal Character Set feature
1 3211 Printer with the Universal Character Set feature
1 3215 Console printer-Keyboard
1 2955
2 3705 Communications Controllers (one with an IBM1 adapter and
the other with a BSCA adapter)
2 2702 Transmission Control Units (with one that supports Teletype
terminals)
1 2314 Direct Access Storage Facility with 8 modules, attached via
an Integrated File Adapter
1 2305 Fixed Head Storage with 8 addresses
2 3330 Disk Storage (One unit has eight modules and the other has
ten. The unit with modules has eight of switchablc between two channels.)
1 3350 Direct Access storage with 8 addresses
1 2401 Magnetic Tape Unit with 4 tape drives
1 3410 Magnetic Tape Unit, Model 3, with 1 tape drive
1 3420 Magnetic Tape Unit, Model 7, with 2 tape drives
1 Multiplexer channel
1 Selector channel
3 Block multiplexer channels
1 Channel-to-Channel Adapter
2 channel interfaces on the 3851 MSC 2 3830-3 control units for access to 3330V devices, each with a
single channel interface
96 3330V Direct Access Storage devices, 48 of which can be
dedicated to one or more virtual machines and 48 of which are to
be used for VM/370 system volumes
4 3330-1 device addresses that are not real spindles, but rather
allow the processor to have direct access to the MSC tables
through the 3830-3 Staging Adapter
Figure 19 shows the real configuration.
