def

previewWindowConfigChanged(description,width,height,bitDepth,rateString,syncString):

print os.system(“/usr/bin/mySyncChangeScript

--sync=”+syncString)

When the video preview timing is changed in the application, this example

function calls a custom external script, mySyncChangeScript, and passes

the sync value to it. That external script could use the sync value, for example,

to trigger a sync change on the sync generator. The output of the external

script is displayed in the application terminal.

Manually Configuring Media Storage

Overview

This section provides advanced instructions for manually configuring a storage

array. Normally, you do not need to perform any of these tasks, as they are

all automatically performed by the XR Configuration Utility.

Creating Hardware LUNs

LUNs, also referred to as Logical Units or Logical Drives, are groups of disk

drives that are striped together to provide optimal performance and RAID

protection. Once configured, LUNs are seen by the Linux operating system as

if they were single disk drives.

To create the LUNs on your XR-series storage, use the XR Configuration Utility

supplied by Autodesk. This utility is installed with the DKU and automates

the LUN creation process.

NOTE For systems having two sets of enclosures, you have to configure one set

at a time with the XR Configuration Utility. Connect the first set of enclosures, and

use the utility to configure it. When done, disconnect the first set and connect the

second set. When the second set of enclosures is configured, re-connect both sets.

To configure LUNs on XR-series storage:

1 Open a terminal and log in as root.
