datadm(1M) System Administration Commands datadm(1M)NAMEdatadm - 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 sup‐
ports 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 ser‐
vice_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 ser‐
vice_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 ser‐
vice_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 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 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"
