NAME
     datadm - maintain DAT static registry file

SYNOPSIS
     /usr/bin/datadm [-v] [-u] [-a service_provider.conf]
          [-r service_provider.conf]


DESCRIPTION
     The datadm utility maintains the DAT static  registry  file,
     dat.conf(4).


     This administrative configuration program allows uDAPL  ser-
     vice  providers to add and remove themselves to the dat.conf
     file.


     You can add or remove interface adapters that a service pro-
     vider supports from a system after its installation. You can
     use datadm to  update  the  dat.conf  file  to  reflect  the
     current state of the system. A new set of interface adapters
     for all the service providers currently installed is  regen-
     erated.

OPTIONS
     The following options are supported:

     -a service_provider.conf

         Enumerate     each     device     entry      in      the
         service_provider.conf(4)  file  into a list of interface
         adapters, that is, interfaces to external  network  that
         are available to uDAPL consumers.


     -r service_provider.conf

         Remove the list of interface adapters  that  corresponds
         to  the  device  entry  in  the service_provider.conf(4)
         file.


     -u

         Update the dat.conf to reflect the current state of  the
         system  with an up to date set of interface adapters for
         the service providers that are currently listed  in  the
         DAT static registry.

     -v

         Display the DAT static registry file, dat.conf.


EXAMPLES
     Example 1 Enumerating a Device Entry


     The following example  enumerates  a  device  entry  in  the
     service_provider.conf(4) file into interface adapters in the
     dat.conf(4) file.



     Assume that SUNW has a service provider  library  that  sup-
     ports  the  device  tavor. It has a service_provider.conf(4)
     file        installed        in        the         directory
     /usr/share/dat/SUNWudaplt.conf  with  a single entry as fol-
     lows:


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




     tavor is an Infiniband Host Channel Adapter with two  ports.
     Both  IB ports exist in a single IB partition, 0x8001. If an
     IB partition is created and plumbed to each port  (with  the
     names  p8001.ibd0 and p8001.ibd1), there will be two IB par-
     tition instances. See  dladm(1M)  for  more  information  on
     creating IB partition data links.


       # dladm show-part

       LINK           PKEY      OVER       STATE      FLAGS
       p8001.ibd0     8001      ibd0       unknown    ----
       p8001.ibd1     8001      ibd1       unknown    ----




     Running the command:


       # datadm -a /usr/share/dat/SUNWudaplt.conf

System Administration Commands                         datadm(1M)



     ...appends two new entries (if they do not already exist) in
     the /etc/dat/dat.conf file:


       p8001.ibd0 u1.2 nonthreadsafe default udapl_tavor.so.1 SUNW.1.0 ""
       "driver_name=tavor"
       p8001.ibd1 u1.2 nonthreadsafe default udapl_tavor.so.1 SUNW.1.0 ""
       "driver_name=tavor"


     Example 2 Updating the dat.conf to Reflect the Current State
     of the System


     A new IB partition, 0x8002, is added to  the  above  example
     covering  port  1  of  the Host Channel Adapter. If a new IB
     partition is created on the port 1/partition 0x8002 with the
     partition link name specified as p8002.ibd0, there will be a
     third IB partition instance: p8002.ibd0.


       # dladm show-part
       LINK           PKEY      OVER       STATE      FLAGS
       p8001.ibd0     8001      ibd0       unknown    ----
       p8001.ibd1     8001      ibd1       unknown    ----
       p8002.ibd0     8000      ibd0       unknown    ----




     Running datadm -u  command,  updates  the  /etc/dat/dat.conf
     file  with a new entry added reflecting the current state of
     the system.



     datadm -v shows that there are  now  three  entries  in  the
     /etc/dat/dat.conf file:


       p8001.ibd0 u1.2 nonthreadsafe default udapl_tavor.so.1 SUNW.1.0 ""
       "driver_name=tavor"
       p8001.ibd1 u1.2 nonthreadsafe default udapl_tavor.so.1 SUNW.1.0 ""
       "driver_name=tavor"
       p8002.ibd0 u1.2 nonthreadsafe default udapl_tavor.so.1 SUNW.1.0 ""
       "driver_name=tavor"
