Because the I/O configuration data and the BS2000 Control System have been separated, the following objects can be generated:
a file containing the I/O configuration data (IOCF – I/O Configuration File) with the IOGEN utility routine (hardware generation)
a BS2000 Control System adjusted to the address space (based on the BS2000 standard EXEC)
Generating the I/O configuration data
Initial installation or a change to the I/O configuration requires (new) generation of the I/O configuration data (hardware generation) with the IOGEN utility routine, see "Generating the I/O configuration data (IOCF) with IOGEN". IOGEN generates the I/O configuration file (IOCF), which defines the entire I/O configuration.
IOCF files can also be created directly in the SE Manager without running BS2000 and transferred to the SVP.
A hardware generation is not required for a version changeover if the I/O configuration remains unchanged.
Disk controllers and/or disk devices can be exchanged under certain circumstances without requiring a hardware generation, see "Disk device configuration".
The I/O configuration (channels, controllers, devices) can be modified during operation (dynamic I/O configuration change), see "I/O configuration".
Customizing the BS2000 Control System
BS2000 Standard EXECs are available on all hardware architectures. A BS2000 control system adjusted to the address space can be generated using the procedure supplied, see the section "Customizing the BS2000 Control System".
