.SH NAME
dat.conf \- DAT static registry
.SH SYNOPSIS
.LP
.nf
\fB/etc/dat/dat.conf\fR
.fi

.SH DESCRIPTION
.sp
.LP
The DAT static registry, \fB/etc/dat/dat.conf\fR is a system-wide data resource
maintained by the system administrative command \fBdatadm\fR(8).
.sp
.LP
\fB/etc/dat/dat.conf\fR 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, \fBibd0\fR. An IPoIB device name
represents an IP interface plumbed by \fBifconfig\fR(8) on an IB
partition/Host Channel Adapter port combination.
.sp
.LP
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
(\fB#\fR) are considered comments. All characters that follow the \fB#\fR are
ignored. Enclose Solaris specific strings (\fISolaris_specific_string\fR) and
service provider's instance data (\fIservice _provider_instance_data\fR) in
quotes.
.sp
.LP
The following shows the order of the fields in a \fBdat.conf\fR entry:
.sp
.in +2
.nf
"\fIinterface_adapter_name\fR" "\fIAPI_version\fR" "\fIthreadsafe\fR | \fInonthreadsafe\fR" \e
"\fIdefault\fR | \fInondefault\fR" "\fIservice_provider_library_pathname\fR" \e
"\fIservice_provider_version\fR" "\fIservice _provider_instance_data\fR"\e
"\fISolaris_specific_string\fR"
.fi
.in -2

.sp
.LP
The fields are defined as follows:
.sp
.ne 2
.na
\fB\fIinterface_adapter_name\fR\fR
.ad
.sp .6
.RS 4n
Specifies the Interface Adapter (IA) name. In IB, this is the IPoIB device
instance name, for example, \fBibd0\fR. This represents an IP interface plumbed
on an IB partition/port combination of the HCA.
.RE

.sp
.ne 2
.na
\fB\fIAPI_version\fR\fR
.ad
.sp .6
.RS 4n
Specifies the API version of the service provide library: For example,
\fB"u"major.minor\fR is \fBu1.2\fR.
.RE

.sp
.ne 2
.na
\fB\fIthreadsafe\fR | \fInonthreadsafe\fR\fR
.ad
.sp .6
.RS 4n
Specifies a threadsafe or non-threadsafe library.
.RE

.sp
.ne 2
.na
\fB\fIdefault\fR | \fInondefault\fR\fR
.ad
.sp .6
.RS 4n
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
\fBdefault\fR with the rest as \fBnondefault\fR.
.RE

.sp
.ne 2
.na
\fB\fIservice_provider_library_pathname\fR\fR
.ad
.sp .6
.RS 4n
Specifies the pathname of the library image.
.RE

.sp
.ne 2
.na
\fB\fIservice_provider_version\fR\fR
.ad
.sp .6
.RS 4n
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, \fBSUNW1.0\fR.
.RE

.sp
.ne 2
.na
\fB\fIservice _provider_instance_data\fR\fR
.ad
.sp .6
.RS 4n
Specifies the service provider instance data.
.RE

.sp
.ne 2
.na
\fB\fISolaris_specific_string\fR\fR
.ad
.sp .6
.RS 4n
Specifies a platform specific string, for example, the device name in the
\fBservice_provider.conf\fR file.

.SH EXAMPLES
.LP
\fBExample 1 \fRSample \fBdat.conf\fR File
.sp
.LP
The following \fBdat.conf\fR file shows a \fBuDAPL 1.2\fR service provider for
\fBtavor, udapl_tavor.so.1\fR supporting two interfaces, \fBibd0\fR and
\fBibd1\fR:

.sp
.in +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 ""

.SH NOTES
.sp
.LP
An empty \fBdat.conf\fR is created during the package \fBSUNWudaplr\fR
installation if no file is present beforehand. Entries in the file are added or
removed by running \fBdatadm\fR(8).
.sp
.LP
The content of the platform specific string does not constitute an API. It is
generated by \fBdatadm\fR(8) and might have a different content or
interpretation in a future release.
