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(1M).

       /etc/dat/dat.conf  contains a list of interface adapters supported by uDAPL service providers. An interface adapter on Infiniband (IB) cor-
       responds to an IPoIB device instance, for example, ibd0. An IPoIB device name represents an IP interface plumbed by ifconfig(1M) 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_spe-
       cific_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(1M).

       The content of the platform specific string does not constitute an API. It is generated by datadm(1M) and might have a different content or
       interpretation in a future release.
