DAT.CONF(5) File Formats and Configurations DAT.CONF(5)

NAME

dat.conf - DAT static registry

SYNOPSIS

/etc/dat/dat.conf

DESCRIPTION

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 quotes.


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"\
"Solaris_specific_string"


The fields are defined as follows:

interface_adapter_name

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.


API_version

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.


service_provider_library_pathname

Specifies the pathname of the library image.


service_provider_version

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.


Solaris_specific_string

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

EXAMPLES

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 ""
"driver_name=tavor"
ibd1 u1.2 nonthreadsafe default udapl_tavor.so.1 SUNW.1.0 ""
"driver_name=tavor"

NOTES

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.
