This topic introduces the set of OpenStorage Technology-related DR Series system CLI commands that enable you to perform the following tasks:
This topic introduces the ost command usage:

NOTE: If you specify a command without supplying the expected value or option, you will be prompted to provide the correct value or option. |
Displays the current OpenStorage Technology (OST) configuration information for a DR Series system. Parameter are described as follows:
config — Displays OST configuration.
file_history — Display(s) history of last 10 OST optimized duplication image file(s).
name — OST container name.
active_files — Display(s) current OST image files being replicated.
name — OST container name.
clients — Displays OST clients.
limits — Replication speed limits.
ost --show

NOTE: To display other types of OST configuration information, substitute the --file_history, --name <name>, or --clients options in the DR Series system CLI command. |
Display the last 10 replicated files that were processed via the DMA optimized duplication process for an OST container (in this example, the container is “ost.”) by running the following:
ost --show --file_history --name ostData replication history: File Peer IP Peer ID Savings Bytes Throughput Replicated At: Encryption /1481068800/w1 10.250.240.232 10 100.00% 107374182400Bytes 1075139KiB/s 2016-12-07 07:58:19 None
Display the OST clients, by running the command: ost --show --clients

|
NOTE: The displayed output when using the DR Series system CLI ost --show --clients command could indicate a fourth type of mode value. Depending upon the client, this value would normally display Auto, Dedupe, or Passthrough. However, you could potentially display a mode value of Mixed, which indicates that you had changed the mode using the DR Series system CLI while the client is still connected. |
|
|
NOTE: Be aware that the mode for clients that were connected to the OST media server before configuration changes might be different that what is shown in the displayed output when using the DR Series system CLI ost --show --clients command. The configuration changes will be updated and reflect any future connections. |
To verify the current state of an OST client, you can check these two sources:
These sources display information about the connected and configured clients. For example, when a system is connected to 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 will change, but any active connections will remain. There are essentially two possible modes: Dedupe and Passthrough. To verify the current mode of an OST client, you can check these two sources of client statistics:
In the Container Statistics page, click the Client Statistics tab (under Connection Type: OST) 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, this indicates that the OST clients are working in the Dedupe mode. If not, this indicates that the OST containers are working in the Passthrough mode.
