Page of GC20-1801-10 As Updated April 1, 1981 by TNt GN25-0837 RIOGEN Macro [ , S RF = (c u u [ , c u u , c u u. • • ]) ]
is the address or a list of addresses of SRF (service record file)
devices used for the 3031, 3032, or 3033 processors. cuu is the
hexadecimal device address that was previously specified in an RDEVICE macro statement. The device type of the SRF is 7443.
In a 3033 AP system, there are two 3036 consoles. This
configuration has four SRF devices, therefore, you should specify
multiple SRF devices at system generation. 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. The FIOGEN macro statement produces an "NOTE warning
message if you specify more than 32 SRF devices.
1. In 3033 MP environments with I/O configured asymmetrically to one
processor, order to access the SRF devices in both 3036 consoles, a channel path must be available from the I/O processor
to both SRF devices.
2. If an SRF device is found to be inaccessible during initialization
of the error recording cylinders, an error message is sent to the
system operator. processing continues, however, the frames from
that SRF device are not placed on the error recording cylinders.
Examples:
The following examples define a primary system console (01F) with an
alternate console (050), a system console (009) with no alternate
console, and a primary system console (01F) with alternates at (050) and (060) • RIOGEN CONS=01F,AtTCONS=050 RIOGEN CONS=009 RIOGEN CONS=01F, AtTCONS=(050, 060) Part 2. Defining Your VM/370 System 157
