Updating the dat.conf file occurs when IPoIB changes occur on the system. You update the registry in two ways.
You can add or remove a list of adapters from the registry that correspond to a device entry in the service provider's configuration file. For this type of updating, you use one of the following commands:
datadm -a serviceprovider.conf adds a list to the registry. For example, to add a list of adapters from a device entry in ABCDudaplt.conf, type the following commands. The second command displays the updated registry.
# datadm -a /usr/share/dat/ABCDudaplt.conf # datadm -v
datadm -r serviceprovider.conf removes a list from the registry. For example, to remove a list of adapters that correspond to a device entry in ABCDudapl.conf, type the following commands. The second command displays the updated registry.
# datadm -r /usr/share/dat/ABCDudaplt.conf # datadm -v
You can also Make the registry reflect the current state of the system with an up to date list of interface adapters for the service providers that are listed in the registry. For this type of updating, you use the following command:
datadm -u
