vRanger 7.8 - Integration Guide for EMC Data Domain Boost (DD Boost)

Setting network timeouts

Previous Next



Backup and restore jobs often take a long time to complete. Although the EMC® Data Domain® Boost (DD Boost™) Library can recover from temporary network interruptions, the operating system on vRanger might terminate a job prematurely if vRanger timeouts are set too low.
NOTE: After losing a network connection, administrators should issue the ddboost reset stats command to clear job connections.

Administering Data Domain and DD Boost > Using the DD Boost commands

This topic describes the EMC® Data Domain® Boost (DD Boost™) commands that you use to manage the DD Boost feature on the EMC® Data Domain® system.
The ddboost command manages the integration of Data Domain systems and disk backup devices. DD Boost is a licensed feature. If basic options do not work, verify that the proper licensing has been implemented on your Data Domain system. The ddboost command includes the following options.
Table 1.  
ddboost access add clients: Add clients to a DD Boost access list.
ddboost access delete clients: Delete clients from DD Boost access list.
ddboost access reset: Reset DD Boost client access list to factory default.

The ifgroup reset command is equivalent to issuing the ddboost ifgroup disable command followed by issuing multiple ddboost ifgroup del interface <IP address> commands.
