Configurations (Other) MULTIPLE SERVICE RECORD FILES In a 3033 attached processor system, there are two 3036 consoles. This
configuration has four service record file devices (one console per
station) . 3033 attached processor environments support multiple service record
file devices. For VM/370 systems operating on a 3033 AP, you should
specify multiple SRF devices at system generation. Code DEVTYPE=7443 in
the RDEVICE macro statement and CUTYPE=7443 in the RCTLUNIT macro
statement to generate support for the SRF devices; also code the ADDRESS=cuu operand in both macro statements. Identify the SRF device
addresses in the RIOGEN macro statement as SRF=(cuu,cuu, ••• ). The SRF addresses you specify in the RIOGEN macro statement should be the same
as the addresses of the SRF devices attached to the service support
consoles.
In 3033 multiprocessing environments with liD configured
asymmetrically to one processor, in order to access the SRF devices in
both 3036 consoles, a channel path must be available from the 110 processor to both SRF devices.
If an SRF device specified on the RIOGEN macro statement is found to
be inaccessible during initialization of the error recording cylinders,
an error message is sent to the system operator; processing continues
without the frames from that SRF device in place on the error recording
cylinders.
The RIOGEN macro statement produces an MNOTE warning message if you specify more than 32 SRF devices. Part 1. Planning for System Generation 127
