3 View the DL/usr/local/flexlm/licenses/DL_license.dat file to check that the render node is licensed
for Burn. It should like something like the below. If it doesn't, contact customer support.
SERVER exuma-001 DLHOST01=886C2B75E8E57E4B03D784C3A2100AC0
DAEMON discreet_l discreet_l
USE_SERVER
4 Repeat the above for the remaining render nodes on the background processing network. If the License
Server for your network is running on a render node, make sure you perform this procedure on this
node as well. Otherwise, this node is able to distribute Burn licenses to other render nodes, but is unable
to retrieve a license for itself.
Test network components
Reviewing log files can help to indicate the source of a problem on the background processing network. For
example, log messages showing network timeouts for jobs may indicate a problem with the TCP/IP protocol
or the Stone and Wire network.
Use the following scripts to test background processing network components and identify the source of
the problem
■ The verifySWConn script is used to test Wire network connectivity in the background processing network.
Refer to Testing Stone and Wire Connectivity for Burn in this topic.
■ The verifyBurnServer script is used to test whether a render node meets minimum hardware requirements
for processing jobs on a network. Refer to Testing Render Node Hardware for Burn in this topic.
Testing Stone and Wire Connectivity for Burn
The following information and procedure applies to workstations and render nodes on a background
processing network.
Use the verifySWConn script to see if problems are due to Stone and Wire. This script can be run from a
workstation or from a render node on the background processing network using the following procedure.
To test, log in to the workstation using the account for the application, or into a render node as root, and
run /usr/discreet/<product_directory>/bin/verifySWConn <options> <Workstation1 Workstation2
...> where: <Workstation1 Workstation2 ...> are the workstations or Burn render nodes on which Stone
and Wire are to be tested. You must specify at least two workstations or render nodes to be tested. <options>
include the following options for this script.
FunctionOption
Verbose.-v
Uses the specified user name to log in to the render node. If this option is omitted,
you may be prompted to provide a username and password. The username must be
valid on the test host.
-l <username>
Testing Render Node Hardware for Burn
Use the verifyBurnServer script to see if a Linux system has the hardware requirements to be used as a
render node. The script also checks if a render node has a supported GPU-accelerated graphics card and
graphics driver version, necessary for processing jobs that require a GPU.
