DATADM(8) Maintenance Procedures DATADM(8)

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(5).

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(5) 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(5) 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(5) file into interface adapters in the dat.conf(5)
file.

Assume that SUNW has a service provider library that supports the device
tavor. It has a service_provider.conf(5) 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 exist) 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"

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"
