dat.conf - DAT static registry




The DAT static registry, /etc/dat/dat.conf is a system-wide data resource
maintained by the system administrative command datadm(8).

/etc/dat/dat.conf contains a list of interface adapters supported by
uDAPL service providers. An interface adapter on Infiniband (IB)
corresponds to an IPoIB device instance, for example, ibd0. An IPoIB
device name represents an IP interface plumbed by ifconfig(8) on an IB
partition/Host Channel Adapter port combination.

Each entry in the DAT static registry is a single line that contains
eight fields. Fields are separated by a SPACE. Lines that begin with a
pound sign (#) are considered comments. All characters that follow the #
are ignored. Enclose Solaris specific strings (Solaris_specific_string)
and service provider's instance data (service _provider_instance_data) in

The following shows the order of the fields in a dat.conf entry:

"interface_adapter_name" "API_version" "threadsafe | nonthreadsafe" \
"default | nondefault" "service_provider_library_pathname" \
"service_provider_version" "service _provider_instance_data"\

The fields are defined as follows:


Specifies the Interface Adapter (IA) name. In IB, this is the IPoIB
device instance name, for example, ibd0. This represents an IP
interface plumbed on an IB partition/port combination of the HCA.


Specifies the API version of the service provide library: For
example, "u"major.minor is u1.2.

threadsafe | nonthreadsafe

Specifies a threadsafe or non-threadsafe library.

default | nondefault

Specifies a default or non-default version of library. A service
provider can offer several versions of the library. If so, one
version is designated as default with the rest as nondefault.


Specifies the pathname of the library image.


Specifies the version of the service provider. By convention, specify
the company stock symbol as the service provider, followed by major
and minor version numbers, for example, SUNW1.0.

service _provider_instance_data

Specifies the service provider instance data.


Specifies a platform specific string, for example, the device name in
the service_provider.conf file.


Example 1: Sample dat.conf File

The following dat.conf file shows a uDAPL 1.2 service provider for tavor,
udapl_tavor.so.1 supporting two interfaces, ibd0 and ibd1:

# dat.conf for uDAPL 1.2
ibd0 u1.2 nonthreadsafe default udapl_tavor.so.1 SUNW.1.0 ""
ibd1 u1.2 nonthreadsafe default udapl_tavor.so.1 SUNW.1.0 ""


See attributes(7) for descriptions of the following attributes:

|Interface Stability | Standard |


libdat(3LIB), service_provider.conf(5), attributes(7), datadm(8),


An empty dat.conf is created during the package SUNWudaplr installation
if no file is present beforehand. Entries in the file are added or
removed by running datadm(8).

The content of the platform specific string does not constitute an API.
It is generated by datadm(8) and might have a different content or
interpretation in a future release.
