Updating the DAT Static Registry

You can use the datadm command to maintain the DAT static registry, the dat.conf file. For more information about this file, see dat.conf(4).

The datadm command can also be used to register or unregister a service provider to the dat.conf file. For more information, see datadm(1M).

When IPoIB interface adapters are added or removed, run the datadm command to update the dat.conf file to reflect the current state of the system. A new set of interface adapters for all the service providers that are currently installed will be regenerated.
