Technical data

This shows the steps for changing the system ID of a specified device from
the factory-supplied ID to 1402193310841 (the system ID for the replacement
device is programmed to match that of the original).

C.3.6 Exiting the DUP Server Utility
After you have completed setting and examining DSSI device parameters, enter
the WRITE command at the PARAMS> prompt to save the device parameters
you have changed using the SET command. The changes are recorded to
nonvolatile memory.
If you have changed the allocation class or node name of a device, the DUP
driver utility will ask you to initialize the controller. Answer Yes (Y) to allow
the changes to be recorded and to exit the DUP driver utility.
If you have not changed the allocation class or node name, enter the EXIT
command at the PARAMS> prompt to exit the DUP driver utility for the specified
device.
This shows the procedure for saving parameter changes. The controller is
initialized.
PARAMS>WRITE
Changes require controller initialization, ok? [Y/(N)] Y

This example shows the DSSI busses for the embedded DSSI adapters after
the unit numbers for the disk devices on bus 0 have been changed from 0, 1,
and 2 to 10, 11, and 12. The bus 0 device names are now DIA10, DIA11, and
DIA12.
