VMS manuals listed in Appendix A or call your Digital service representative. On the VAX 4000 Model 100 system, an embedded DSSI adapter on the KA52 CPU provides the interface between the CPU and the DSSI storage devices. The adapter provides a DSSI bus that can support up to eight nodes, where...
• NODENAME • SYSTEMID • DSSI NODE ID Note Each of the above parameters, with the exception of the Bus Node ID, are programmed and examined using the console-based Diagnostic and Utility Program (DUP) driver utility. The Bus Node ID is physically determined by jumpers on disk drive.
Table C–1 RF31T/RF35 DSSI ID Jumper Combinations DSSI ID Pin 5 Pin 3 Pin 1 A brief description of each parameter follows. The Bus Node ID parameter is provided by the jumpers on the disks. Each DSSI bus can support up to eight nodes, 0–7. Each DSSI adapter and each device count as a node.
The FORCEUNI parameter controls the use of UNITNUM to override the default device unit number supplied by the jumpers. When FORCEUNI is set to a value of zero, the operating system uses the value assigned to the UNITNUM parameter; when FORCEUNI is set to a value of one, the operating system uses the value supplied by the jumpers.
C.3 Examining and Setting DSSI Device Parameters The following instructions describe how to change DSSI parameters, using the DUP driver utility. In the example procedures, the allocation class will be set to 2. 1. Enter the console mode. The procedure for programming parameters for DSSI devices from console mode requires that you issue commands to those devices at the console prompt .
