NAME

       datadm - maintain DAT static registry file

SYNOPSIS

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

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

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

       You  can  add  or  remove  interface  adapters that a service provider 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  cur-
       rently installed is regenerated.

       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.

       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 supports 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 follows:

       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  IP  interface	is
       plumbed to each port, there are two IPoIB device instances, ibd0 and ibd1:

       # ls -l /dev/ibd*
       /dev/ibd0 -> /devices/pci@1/pci15b3,5a44@0/ibport@1,8001,ipib:ibd0
       /dev/ibd1 -> /devices/pci@1/pci15b3,5a44@0/ibport@2,8001,ipib:ibd1

       Running	the  command,  datadm  -a  /usr/share/dat/SUNWudaplt.conf  appends  two  new  entries  (if  they  do  not  already exists]) in the
       /etc/dat/dat.conffile:

       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"

       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 IP interface is  plumbed	to
       port 1/partition 0x8002, there is a third IPoIB device instance: ibd2.

       # ls -l /dev/ibd*
	/dev/ibd0 -> /devices/pci@1/pci15b3,5a44@0/ibport@1,8001,ipib:ibd0
	/dev/ibd1 -> /devices/pci@1/pci15b3,5a44@0/ibport@2,8001,ipib:ibd1
	/dev/ibd2 -> /devices/pci@1/pci15b3,5a44@0/ibport@1,8002,ipib:ibd2

       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:

       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"
       ibd2 u1.2 nonthreadsafe default udapl_tavor.so.1 SUNW.1.0 ""
       "driver_name=tavor"

       /etc/dat/dat.conf       DAT static registry file
