 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 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 currently installed is
regenerated.
 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 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\e
 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"
