The set of
RDA commands have the following functions:
- Displays command specific information.
- Deletes the Rapid Data Access (RDA) client.
- Updates attributes of a Rapid Data Access (RDA) client.
- Limits bandwidth consumed by Rapid Data Access (RDA) when replicating over a WAN link.
- Lists or cleans up partial images.
The following commands are run for RDA:
- rda --show
- rda --update
- rda --delete_clientrda --update_client
- rda --limit
- rda --partial_images --containerid [options]
Description
The command displays the RDA-specific configurations.

[--active_files] [--name <name>]
[--clients]
[--limits]
--config Displays RDA configuration.
--file_history Display(s) history of last 10 RDA optimized
deduplication image file(s).
--name RDA container name.

NOTE: The displayed output when using the rda --show --clients command indicates a fourth type of mode value. Depending upon the client, this value equals Auto, Dedupe, Passthrough, or Mixed. Mixed indicates that you changed the mode while the client is still connected. |
|
|
NOTE: The mode for clients that are connected to the RDA media server before configuration changes might be different than what is displayed when using the rda --show --clients command. The configuration changes are updated to reflect any future connections. |
To verify the current state of an RDA client, you can check the two sources:
- DR Series system CLI, using the
rda --show --clients command
- DR Series system GUI, displaying the Clients page
These sources display information about the connected and configured clients. When a system is connected multiple times, these sources show the number of connections to that client and the mode. You can also change the mode from dedupe to the other supported modes. When this is done the displayed mode changes, but any active connections remains. There are essentially two possible modes: Dedupe and Passthrough. To verify the current mode of an RDA client, you can check the two sources of client statistics:
- DR Series system CLI, using the
stats --container --name command
- DR Series system GUI, displaying the Container Statistics page
In the Container Statistics page, click the Client Statistics tab (under Connection Type: RDS) to display the Client Statistics table. If the Network Savings level in this table displays some savings and the displayed Bytes Ingested value is different from the displayed Bytes Transferred, it indicates that the RDA clients are working in the Dedupe mode. If not, it indicates that the RDA containers are working in the Passthrough mode.
