HP Scalable Visualization Array Version 1.1 System Administration Guide

• Copy the data files to the head node as in the previous option. Use the Administrative Network (GigE)
rather than the SI to share the data files to all other nodes. This option is useful if the application loads
the SI, for example; with MPI traffic.
• Access the data files stored on an external file system such as HP SFS. You can access the data directly
from the visualization nodes using GigE NICs in the nodes. It is also possible to make use of the SI for
the data traffic. Configuring parallel data flows from the file system using the SI to the visualization
nodes offers the fastest method of data distribution.
Mounting external and internal file systems is described in the HP XC documentation How To section. A link
to the HP XC documentation is available from the online SVA Documentation Library.
Managing Licenses
This section addresses the following topics:
• A description of the license manager and the license file.
• A means to determine whether the license manager is running.
• Instructions on how to start and stop the license manager.
Overview
The license manager service runs on the head node and maintains licensing information for software on the
SVA. You can find additional information on the FLEXlm™ license manager at the Macrovision Web site:
http://www.macrovision.com
This link is available from the SVA Documentation Library.
The license manager uses a license file to maintain all licenses associated with the SVA. The
/opt/sva/etc/license/SVA.lic file is the license file for the SVA system.
You can update the SVA license file to include a future additional product and to update the expiration.
Under normal operation, you don't need to start or stop the license manager. Under exceptional circumstances,
such as finding that the manager has stopped unexpectedly, follow the instructions in this section. To install
a license, stop the license manager, install the file, and start the license manager.
Update the license /opt/sva/etc/license/SVA.lic file with the text editor of your choice.
The /var/log/svalicense.log file is the log file for the license manager.
Determining Whether the License Manager Is Running
Log in to the head node as superuser and execute the following command to determine whether or not the
license manager is running:
# service sva-lm status
The following output is typical when the license manager is running:
sva-lm is running.
License manager process id: ####
HPQ license manager process id: ####
The following output indicates that the license manager is not running:
sva-lm is stopped.
Starting and Stopping the License Manager
The service command enables you to start, stop, and restart the license manager service from the head
node.
Execute the following command to start the license manager:
# service sva-lm start
Execute the following command to stop the license manager:
# service sva-lm stop
Execute the following command to restart the license manager:
