Modifying an interface group
After the interface group is set up, you can add or delete interfaces from the group. The following example shows how to remove an interface from the configured interface group on the EMC® Data Domain® system.
Remove the interface from the group on Data Domain system:
If you use the net command to change the interface, such as enabling an interface that is configured for ifgroup, run the ddboost show connections command to update the load balancing view. This updating allows the ifgroup to use the interface. For more information about the ddboost show connections command, see Show connections.
Removing advanced load balancing and link failover configuration
The following example illustrates removing a configured interface group on the EMC® Data Domain® system.
Setting network timeouts
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.
EMC recommends setting timeouts to at least 30 minutes (1800 seconds).
NOTE: After losing a network connection, administrators should issue the ddboost reset stats command to clear job connections.
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.
NOTE: For information about configuring DD Boost using the graphical user interface (GUI)-based Enterprise Manager, see the EMC Data Domain Operating System Administration Guide.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.
Access
• 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.
• ddboost access show: Show DD Boost client access list.Destroy
You must also manually remove (expire) the corresponding catalog entries.
Disable
Administrators use this command to disable DD Boost for the Data Domain system.
Enable
Administrators use this command to enable DD Boost for the Data Domain system.
Ifgroup add interface
ddboost ifgroup add interface <IP address>Ifgroup del interface
Administrators use this command to remove a valid IP address added as an interface.
ddboost ifgroup del interface <IP address>Ifgroup disable
Ifgroup enable
Ifgroup reset
The ifgroup reset command is equivalent to issuing the ddboost ifgroup disable command followed by issuing multiple ddboost ifgroup del interface <IP address> commands.
Ifgroup show config
Option reset
Option set
Option show
Use this command to show whether the distributed segment processing option is enabled or disabled.
Reset stats
Reset user-name
Set user-name
ddboost set user-name <user-name>Show connections
Use this command to show the number of active clients, and for each active client:
Show histogram
Use this command to display a DD Boost histogram for the Data Domain system.
• op: The name of the NFS operation.
• mean-ms: The mathematical mean time for completion of the operations.
• stddev: The standard deviation for time to complete operations, derived from the mean time.
• max-s: The maximum time taken for a single operation.
• 2,4,6,8, or 10ms: The number of operations that took less than the specified number of milliseconds (ms).
• 100ms: The number of operations that took between 10 ms and 100 ms.
• 1s: The number of operations that took between 100 ms and one second.
• 10s: The number of operations that took between 1 second and 10 seconds.
• >10s: The number of operations that took over 10 seconds.Show stats
